Published: April 2021

Background

Olive orchards are threatened by a wide range of pathogens. Of these, Verticillium dahliae has been in the spotlight for its high incidence, the difficulty to control it and the few cultivars that has increased tolerance to the pathogen. Disease resistance not only depends on detection of pathogen invasion and induction of responses by the plant, but also on barriers to avoid the invasion and active resistance mechanisms constitutively expressed in the absence of the pathogen. In a previous work we found that two healthy non-infected plants from cultivars that differ in V. dahliae resistance such as ‘Frantoio’ (resistant) and ‘Picual’ (susceptible) had a different root morphology and gene expression pattern. In this work, we have addressed the issue of basal differences in the roots between Resistant and Susceptible cultivars.

Results

The gene expression pattern of roots from 29 olive cultivars with different degree of resistance/susceptibility to V. dahliae was analyzed by RNA-Seq. However, only the Highly Resistant and Extremely Susceptible cultivars showed significant differences in gene expression among various groups of cultivars. A set of 421 genes showing an inverse differential expression level between the Highly Resistant to Extremely Susceptible cultivars was found and analyzed. The main differences involved higher expression of a series of transcription factors and genes involved in processes of molecules importation to nucleus, plant defense genes and lower expression of root growth and development genes in Highly Resistant cultivars, while a reverse pattern in Moderately Susceptible and more pronounced in Extremely Susceptible cultivars were observed.

Conclusion

According to the different gene expression patterns, it seems that the roots of the Extremely Susceptible cultivars focus more on growth and development, while some other functions, such as defense against pathogens, have a higher expression level in roots of Highly Resistant cultivars. Therefore, it seems that there are constitutive differences in the roots between Resistant and Susceptible cultivars, and that susceptible roots seem to provide a more suitable environment for the pathogen than the resistant ones.

Published: April 2021

Background

Greater yam (Dioscorea alataL.) is a major tropical and subtropical staple crop cultivated for its starchy tubers. Breeding of this dioecious species is hampered by its erratic flowering, yet little is currently known on the genetic determinism of its sexual reproduction.

Result

Here we used a genome-wide association approach and identified a major genetic barrier to reproduction in yam on chromosome 1, as represented by two candidate genes. A deleterious effect on male fitness could be hypothesized considering the involvement of these two genes in male reproduction and the low frequency of this non-flowering dominant allele within the male genepool. We also extended the hypothesis of a XX/XY sex-determination system located on chromosome 6 inD. alatato encompass most of the species diversity. Moreover, a kompetitive allele-specific PCR (KASPar) marker was designed and validated that enables accurate cultivar sex estimation. The reconstruction of chromosome 6 associated with the detection of highly putative structural variations confirmed the possible involvement of a major part of the chromosome.

Conclusion

The findings of this study, combined with proper estimation of accession ploidy levels to avoid endosperm incompatibility issues, could facilitate the design of future promising parental combinations inD. alatabreeding programs. Moreover, the discovery of this genetic barrier to reproduction opens new avenues for gaining insight into yam reproductive biology and diversification.
Diagnostic and treatment barriers to persistent somatic symptoms in primary care – representative survey with physicians
Authors: Lehmann Marco , Pohontsch Nadine Janis , Zimmermann Thomas , Scherer Martin , Löwe Bernd
Published: April 2021

Background

Many patients consult their primary care physician with persistent somatic symptoms such as pain or sickness. Quite often these consultations and further diagnostic measures yield no medical explanation for the symptoms – patients and physicians are left in uncertainty. In fact, diagnostic and treatment barriers in primary care hinder timely health-care provision for patients suffering from persistent somatic symptoms (PSS). The significance of individual barriers is still unknown. We compare and quantify these barriers from the perspective of primary care physicians and identify subpopulations of primary care physicians who experience particular barriers as most severe.

Methods

We mailed a questionnaire to primary care physicians (PCP) in Germany and asked them which barriers they consider most important. We invited a random sample of 12,004 primary care physicians in eight federal states in Germany. Physicians provided anonymous mailed or online responses. We also mailed a postcard to announce the survey and a mail reminder. Main measures were Likert rating scales of items relating to barriers in the diagnosis and treatment of PSS in primary care. Information on demography and medical practice were also collected.

Results

We analyzed 1719 data sets from 1829 respondents. PCPs showed strongest agreement with statements regarding (1.) their lack of knowledge about treatment guidelines, (2.) their perceptions that patients with PSS would expect symptom relief, (3.) their concern to overlook physical disease in these patients, and (4.) their usage of psychotropic drugs with these patients. More experienced PCPs were better able to cope with the possibility of overlooking physical disease than those less experienced.

Conclusions

The PCPs in our survey answered that the obligation to rule out severe physical disease and the demand to relieve patients from symptoms belong to the most severe barriers for adequate treatment and diagnosis. Moreover, many physicians admitted to not knowing the appropriate treatment guidelines for these patients. Based on our results, raising awareness of guidelines and improving knowledge about the management of persistent somatic symptoms appear to be promising approaches for overcoming the barriers to diagnosis and treatment of persistent somatic symptoms in primary care.

Hypertensive disorders of pregnancy (HDP) management pathways: results of a Delphi survey to contextualise international recommendations for Indonesian primary care settings
Authors: Ekawati Fitriana Murriya , Licqurish Sharon , Gunn Jane , Brennecke Shaun , Lau Phyllis
Published: April 2021

Background

Hypertensive disorders of pregnancy (HDP) are a significant contributor to the high maternal mortality rate in Indonesia. At the moment, limited guidelines are available to assist primary care providers in managing HDP cases. A previous review of 16 international HDP guidelines has identified opportunities for improving HDP management in Indonesian primary care, but it has not determined the suitability of the recommendations in practice. This study aims to achieve consensus among the experts regarding the recommendations suitability and to develop HDP pathways in Indonesian primary care.

Methods

Maternal health experts, including GPs, midwives, nurses, medical specialists and health policy researchers from Indonesia and overseas were recruited for the study. They participated in a consensus development process that applied a mix of quantitative and qualitative questions in three Delphi survey rounds. At the first and second-round survey, the participants were asked to rate their agreement on whether each of 125 statements about HDP and HDP management is appropriate for use in Indonesian primary care settings. The third-round survey presented the drafts of HDP pathways and sought participants’ agreement and further suggestions. The participants’ agreement scores were calculated with a statement needing a minimum of 70% agreement to be included in the HDP pathways. The participants’ responses and suggestions to the free text questions were analysed thematically.

Results

A total of 52 participants were included, with 48, 45 and 37 of them completing the first, second and third round of the survey respectively. Consensus was reached for 115 of the 125 statements on HDP definition, screening, management and long-term follow-up. Agreement scores for the statements ranged from 70.8–100.0%, and potential implementation barriers of the pathways were identified. Drafts of HDP management pathways were also agreed upon and received suggestions from the participants.

Conclusions

Most evidence-based management recommendations achieved consensus and were included in the developed HDP management pathways, which can potentially be implemented in Indonesian settings. Further investigations are needed to explore the acceptability and feasibility of the developed HDP pathways in primary care practice.
Universal prevention of distress aimed at pregnant women: a systematic review and meta-analysis of psychological interventions
Authors: Missler Marjolein , Donker Tara , Beijers Roseriet , Ciharova Marketa , Moyse Charlotte , de Vries Ralph , Denissen Jaap , van Straten Annemieke
Published: April 2021

Background

There is sufficient meta-analytic evidence that antenatal interventions for women at risk (selective prevention) or for women with severe psychological symptoms (indicated prevention) are effective in reducing postpartum distress. However, women without risk or severe psychological symptoms might also experience distress. This meta-analysis focused on the effectiveness of preventive psychological interventions offered touniversalpopulations of pregnant women on symptoms of depression, anxiety, and general stress. Paternal and infant outcomes were also included.

Method

We included 12 universal prevention studies in the meta-analysis, incorporating a total of 2559 pregnant women.

Results

Overall, ten studies included depression as an outcome measure, five studies included stress, and four studies anxiety. There was a moderate effect of preventive interventions implemented during pregnancy on the combined measure of maternal distress (d = .52), on depressive symptoms (d = .50), and on stress (d = .52). The effect on anxiety (d = .30) was smaller. The effects were not associated with intervention timing, intervention type, intervention delivery mode, timing of post-test, and methodological quality. The number of studies including partner and/or infant outcomes was too low to assess their effectiveness.

Conclusions

This meta-analysis suggests that universal prevention during pregnancy is effective on decreasing symptoms of maternal distress compared to routine care, at least with regard to depression. While promising, the results with regard to anxiety and stress are based on a considerably lower number of studies, and should thus be interpreted with caution. More research is needed on preventing other types of maternal distress beyond depression. Furthermore, there is a lack of research with regard to paternal distress. Also, given the large variety in interventions, more research is needed on which elements of universal prevention work. Finally, as maternal distress symptoms can affect infant development, it is important to investigate whether the positive effects of the preventive interventions extend from mother to infant.

Mixed methods assessment of impact on health awareness in adult childhood cancer survivors after viewing their personalized digital treatment summary and follow-up recommendations
Authors: Linge Helena M. , Follin Cecilia
Published: April 2021

Background

The survival rate after childhood cancer has improved to 80%. The majority of childhood cancer survivors (CCS) will experience late complications which require follow up care, including access to their individual cancer treatment summary. The need to understand CCS needs and preferences in terms of ways to receive information e.g. digitally, becomes important. This study aims to through a mixed methods approach a) examine how CCS’ health awareness was impacted by viewing their personalized digital treatment summary and follow-up recommendations, b) explore E health literacy, and c) determine self-reported survivorship experiences and health care usage.

Methods

Survivors with a recent visit to the Late effects clinic were eligible for the study (n = 70). A representative sample of primary diagnoses were invited (n = 28). 16 CCS were enrolled. Recent medical visits, e health literacy and impressions of the digital treatment summary were assessed by a survey in conjunction with viewing their digital treatment summary on a computer screen. Their experience of reading and understanding their digital treatment summary in the context of their health related survivorship experiences were assessed in focus groups. The transcribed data was analyzed with conventional qualitative content analysis.

Results

The self-reported medical problems largely reflected that, only 6,3% reported no cancer-related reasons for seeking medical attention. Of the medical specialists, the primary care physician was the most frequently visited specialist (68.8%). High E health literacy was not associated with treatment features but with educational level (p = 0.003, CI: 3.9–14.6) and sex (p = 0.022, CI: − 13.6- -1.3). All survivors graded the digital treatment summary above average in terms of being valuable, agreeable and comprehensive. The focus group interviews identified three themes: 1) The significance of information, 2) The impact of awareness; and 3) Empowerment.

Conclusions

Reading the treatment summaries furthered the survivors understanding of their health situation and consequently aided empowerment. A digital treatment summary, provided by knowledgeable health care professionals, may increase the self-managed care and adherence to follow-up recommendations. Further insights into e health literacy in larger samples of CCS may determine to what extent health-related information can be communicated via digital resources to this at risk population.
Cervical cancer screening patterns among HIV-positive women in Estonia: a population-based retrospective cohort study
Authors: Tisler Anna , Ojavee Sven Erik , Veerus Piret , Soodla Pilleriin , Uusküla Anneli
Published: April 2021

Background

The World Health Organisation (WHO) calls for the elimination of cervical cancer (CC) as a public health issue. To achieve elimination, efforts must be aligned and accelerated. Women living with HIV (WLWH) have excess risk for developing, and dying from, CC over the general population. Estimates of cervical cancer screening programme coverage in Eastern European countries that have experienced HIV epidemics since the early 2000’s are scarce.

Method

This population-based retrospective study uses a healthcare administrative database and follows cohorts of all WLWH in a ratio of 1:3 randomly matched (age, region) HIV negative women from 2009 to 2018. Annual and longitudinal (over the whole study period) coverage for cervical cancer screening (opportunistic, organised, HIV specific) and adjusted odds ratios (AORs) for longitudinal screening coverage predictors were estimated from 2009 to 2018.

Results

Among WLWH and HIV-negative women, the mean annual coverage with opportunistic screening was 61.45 and 65.59%; and organised screening was 20.4 and 28.7%, respectively (both: p < 0.00001). 19.01% (95% CI 18.05–19.97) HIV-negative and 13.9% (95% CI 12.35–15.45) WLWH were longitudinally covered with organised cervical cancer screening. Among WLWH, the mean annual HIV-specific cervical cancer screening coverage was 49.4, and 24.3% were longitudinally covered. Longitudinal coverage with HIV-specific cervical cancer screening was inversely associated with age, hepatitis C virus (HCV) co-infection (AOR 0.754, 95% CI 0.619, 0.916), not having insurance (AOR 0.331, 95% CI 0.264, 0.412), drug abuse (AOR 0.459, 95% CI 0.336, 0.618) and higher among those retained in HIV care (AOR 1.972, 95% CI 1.615, 2.410). Among HIV-negative women, longitudinal coverage with organised cervical cancer screening was inversely associated with residence in the region and higher among older women.

Conclusions

Our results highlight unacceptably low coverage of cervical cancer screening of WLWH in Estonia. There is need for dedicated cervical cancer screening efforts for WLWH considering the high cancer risk and rate in the study population.
In search of the optimum structural model for Internet Gaming Disorder
Authors: Stavropoulos Vasileios , Gomez Rapson , Griffiths Mark D.
Published: April 2021

Background

Internet gaming Disorder (IGD) constitutes a recently proposed clinical disorder (American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 2013). The present study examined if IGD is best conceptualized as categorical (present/absent), or dimensional (severity ranging from low to high), or both (i.e., hybrid of categorical/dimensional).

Methods

Ratings of the nine DSM-5 IGD symptoms, as presented in the Internet Gaming Disorder Scale 9-Short Form (Pontes & Griffiths, Comput Hum Behav 45:137-143, 2015), from 738 gamers, aged 17 to 72 years, were collected. Confirmatory factor analysis (CFA), latent class analysis (LCA), and factor mixture modelling analysis (FMMA) procedures were applied to determine the optimum IGD model.

Results

Although the findings showed most support for a FFMA model with two classes and one factor, there was also good statistical and substantive support for the one-factor CFA model, and the LCA model with three classes.

Conclusion

It was concluded that while the optimum structure of IGD is most likely to be a hybrid model (i.e., concurrently categorical and dimensional), a uni-dimensional model and/or a three-class categorical model are also plausible.
How can community engagement in health research be strengthened for infectious disease outbreaks in Sub-Saharan Africa? A scoping review of the literature
Authors: Vanderslott Samantha , Van Ryneveld Manya , Marchant Mark , Lees Shelley , Nolna Sylvie Kwedi , Marsh Vicki
Published: April 2021

Background

Community engagement (CE) is a well-established practical and scholarly field, recognised as core to the science and ethics of health research, for which researchers and practitioners have increasingly asked questions about desired standards and evaluation. In infectious disease outbreak contexts, questions may be more complex. However, it is unclear what body of knowledge has been developed for CE specifically as it applies to emerging infectious diseases. This scoping review seeks to describe (1) How CE has been conceptualised and understood; and (2) What conclusions have research teams reached on the effectiveness of CE in these settings, including challenges and facilitators.

Methods

We used a scoping review framework by Arksey and O’Malley (Int J Soc Res Methodol 8:19–32, 2005) to structure our review. We conducted a brainstorming session and initial trial search to inform the protocol, search terms, and strategy. Three researchers discussed, developed and applied agreed screening tools and selection criteria to the final search results. Five researchers used the screening tools to screen abstracts and full text for inclusion by consensus. Additional publications were sought from references of retrieved publications and an expert call for literature. We analysed and reported emerging themes qualitatively.

Results

We included 59 papers from a total of 722 articles derived from our trial and final literature searches, as well as a process of “citation chasing” and an expert call for grey literature. The core material related exclusively to health research trials during the 2014–2016 West Africa Ebola outbreak. We synthesized reports on components of effectiveness of CE to identify and propose three themes as essential elements of effective CE.

Conclusions

While there is a large volume of literature documenting CE activities in infectious disease research settings generally, there are few accounts of effectiveness dimensions of CE. Our review proposes three themes to facilitate the effectiveness of CE initiatives as essential elements of CE activities in infectious diseases studies: (1) Communication towards building collaborative relationships; (2) Producing contextual knowledge; and (3) Learning lessons over time. As there were relatively few in-depth accounts of CE from our literature review, documentation and accounts of CE used in health research should be prioritised.
Macro- and meso-level contextual influences on health care inequities among American Indian elders
Authors: Willging Cathleen E. , Jaramillo Elise Trott , Haozous Emily , Sommerfeld David H. , Verney Steven P.
Published: April 2021

Background

American Indian elders, aged 55 years and older, represent a neglected segment of the United States (U.S.) health care system. This group is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other aging populations in the country. Despite the U.S. government’s federal trust responsibility to meet American Indians’ health-related needs through the Indian Health Service (IHS), elders are negatively affected by provider shortages, limited availability of health care services, and gaps in insurance. This qualitative study examines the perspectives of professional stakeholders involved in planning, delivery of, and advocating for services for this population to identify and analyze macro- and meso-level factors affecting access to and use of health care and insurance among American Indian elders at the micro level.

Methods

Between June 2016 and March 2017, we undertook in-depth qualitative interviews with 47 professional stakeholders in two states in the Southwest U.S., including health care providers, outreach workers, public-sector administrators, and tribal leaders. The interviews focused on perceptions of both policy- and practice-related factors that bear upon health care inequities impacting elders. We analyzed iteratively the interview transcripts, using both open and focused coding techniques, followed by a critical review of the findings by a Community Action Board comprising American Indian elders.

Results

Findings illuminated complex and multilevel contextual influences on health care inequities for elders, centering on (1) gaps in elder-oriented services; (2) benefits and limits of the Affordable Care Act (ACA); (2) invisibility of elders in national, state, and tribal policymaking; and (4) perceived threats to the IHS system and the federal trust responsibility.

Conclusions

Findings point to recommendations to improve the prevention and treatment of illness among American Indian elders by meeting their unique health care and insurance needs. Policies and practices must target meso and macro levels of contextual influence. Although Medicaid expansion under the ACA enables providers of essential services to elders, including the IHS, to enhance care through increased reimbursements, future policy efforts must improve upon this funding situation and fulfill the federal trust responsibility.
Three case studies of community behavioral health support from the US Department of Veterans Affairs after disasters
Authors: Wyte-Lake Tamar , Schmitz Susan , Kornegay Reginald J. , Acevedo Felix , Dobalian Aram
Published: April 2021

Background

Community disaster resilience is comprised of a multitude of factors, including the capacity of citizens to psychologically recover. There is growing recognition of the need for public health departments to prioritize a communitywide mental health response strategy to facilitate access to behavioral health services and reduce potential psychological impacts. Due to the US Department of Veterans Affairs’ (VA) extensive experience providing trauma-informed behavioral healthcare to its Veterans, and the fact that VA Medical Centers (VAMCs) are located throughout the United States, the VA is well situated to be a key partner in local communities’ response plans. In this study we examined the role the VA can play in a community’s behavioral health response using case studies from three disasters.

Methods

This study investigated experiences of VA employees in critical emergency response positions (N = 17) in communities where disasters occurred between 2017 and 2019. All respondents were interviewed March–July 2019. Data were collected via semi-structured interviews exploring participants’ experiences and knowledge about VA activities provided to communities following the regional disasters. Data were analyzed using thematic and grounded theory coding methods.

Results

Respondents underscored VA’s primary mission after a disaster was to maintain continuity of care to Veterans. The majority also described the VA supporting community recovery. Specifically, three recent events provided key examples of VA’s involvement in disaster behavioral health response. Each event showed VA’s integration into local response structures was facilitated by pre-existing emergency management and clinical relationships as well as prioritization from VA leadership to engage in humanitarian missions. The behavioral health interventions were provided by behavioral health teams integrated into disaster assistance centers and non-VA hospitals, VA mobile units deployed into the community, and VA telehealth services.

Conclusions

Recent disasters have revealed that coordinated efforts between multidisciplinary agencies can strengthen communities’ capacity to respond to mental health needs, thereby fostering resilience. Building relationships with local VAMCs can help expedite how VA can be incorporated into emergency management strategies. In considering the strengths community partners can bring to bear, a coordinated disaster mental health response would benefit from involving VA as a partner during planning.
Closing the gap between practice and science in school- and community-based participatory physical literacy promotion: study protocol of the StuPs project
Authors: Wessely Stefanie , Starke Dagmar , Weyers Simone , Joisten Christine
Published: April 2021

Background

The role of physical activity in the promotion of children’s well-being and health is widely known. However, research indicates that the time spent physically exercising and participating in organized sport activities is decreasing among children. Although there is currently no gold standard for promoting sustainable physical activity in children, community-based approaches, particularly those that are multicomponent, appear to be the most successful. The project StuPs: a school- and community-based participatory approach for promoting physical activity in children and their families aims to develop a community-based approach to promoting physical activity by increasing physical literacy among elementary school children and their household members.

Methods

The project is built upon the intervention mapping approach and consists of two periods with an overall duration of 3 years. Period I will last 9 months and include an assessment of needs, wants, strengths, and weaknesses regarding physical activity and health promotion at the community- and school-based level according to the keywords “capacity building” and “physical literacy.” Based on the knowledge gained in this stage, measures for capacity building to promote healthy lifestyles and physical literacy in children will be developed using the community-based participatory research and capacity building approach. In Period II, the measures will be applicated, implemented and evaluated using a pre−/post-design to assess efficacy.

Discussion

Although the efficacy of using community-based and capacity building approaches to reach children is promising, there remains a gap regarding best practices for changing existing structures and habits over the long term and in the sense of promoting physical literacy.
Frailty status changes are associated with healthcare utilization and subsequent mortality in the elderly population
Authors: Li Chia-Ming , Lin Chih-Hsueh , Li Chia-Ing , Liu Chiu-Shong , Lin Wen-Yuan , Li Tsai-Chung , Lin Cheng-Chieh
Published: April 2021

Background

This study determined (1) whether a change in frailty status after a 1 year follow up is associated with healthcare utilization and evaluated (2) whether a change in frailty status after a 1 year follow up and health care utilization are associated with all-cause mortality in a sample of Taiwan population.

Methods

This work is a population-based prospective cohort study involving residents aged ≥65 years in 2009. A total of 548 elderly patients who received follow-ups in the subsequent year were included in the current data analysis. Fried frailty phenotype was measured at baseline and 1 year. Information on the outpatient visits of each specialty doctor, emergency care utilization, and hospital admission during the 2 month period before the second interview was collected through standardized questionnaires administered by an interviewer. Deaths were verified by indexing to the national database of deaths.

Results

At the subsequent 1 year follow-up, 73 (13.3%), 356 (64.9%), and 119 (21.7%) elderly participants exhibited deterioration, no change in status, and improvement in frailty states, respectively. Multivariate logistic analysis showed the high risk of any type of outpatient use (odds ratios [OR] 1.94, 95% confidence interval [CI] 1.02–3.71) among older adults with worse frailty status compared with those who were robust at baseline and had unchanged frailty status after 1 year. After multivariate adjustment, participants with high outpatient clinic utilization had significantly higher mortality than those with low outpatient clinic visits among unchanged pre-frail or frail (hazard ratios [HR] 2.79, 95% CI: 1.46–5.33) and frail to pre-frail/robust group (HR 9.32, 95% CI: 3.82–22.73) if the unchanged robustness and low outpatient clinic visits group was used as the reference group.

Conclusions

The conditions associated with frailty status, either after 1 year or at baseline, significantly affected the outpatient visits and may have increased medical expenditures. Combined change in frailty status and number of outpatient visits is related to increased mortality.
Epidemiological investigation and intergenerational clinical characteristics of 24 coronavirus disease patients associated with a supermarket cluster: a retrospective study
Authors: Tian Suochen , Wu Min , Chang Zhenqin , Wang Yunxia , Zhou Guijie , Zhang Wenming , Xing Junmin , Tian Hui , Zhang Xihong , Zou Xiuli , Zhang Lina , Liu Mingxin , Chen Juan , Han Jian , Ning Kang , Chen Shuangfeng , Wu Tiejun
Published: April 2021

Background

In view of the ongoing coronavirus disease (COVID-19) pandemic, it remains unclear whether the severity of illness and time interval from symptom onset to release from quarantine differ between cases that originated from clusters and cases reported in other areas. This study aimed to assess epidemiological and intergenerational clinical characteristics of COVID-19 patients associated with cluster outbreaks to provide valuable data for the prevention and control of COVID-19.

Methods

We identified the first employee with COVID-19 at a supermarket and screened the close contacts of this index patient. Confirmed cases were divided into two groups according to the generation (first generation comprising supermarket employees [group A] and second or third generations comprising family members or friends of the supermarket employees [group B]). The epidemiological and clinical characteristics of the two groups were retrospectively compared.

Results

A total of 8437 people were screened, and 24 COVID-19 patients were identified. Seven patients (29.2%) were asymptomatic; three patients were responsible for six symptomatic cases. The interval from the confirmation of the first case to symptom onset in symptomatic patients was 5–11 days. The clinical manifestations of symptomatic patients upon admission were non-specific. All patients (including the seven asymptomatic patients) were admitted based on chest computed tomography features indicative of pneumonia. There were 11 cases in group A (first generation) and 13 cases in group B (second generation, 11 cases; third generation, 2 cases), with no significant differences in clinical and epidemiological characteristics between the two groups, except for sex, duration from symptom onset to hospitalization, and underlying disease (P > 0.05).

Conclusions

For cluster outbreaks, it is important to comprehensively screen close the contacts of the index patient. Special attention should be paid to asymptomatic cases. The clinical management of cluster patients is similar to that of other COVID-19 patients.
Assessment of pain and postoperative nausea and vomiting and their association in the early postoperative period: an observational study from Palestine
Authors: Elsaid Reem M. , Namrouti Ashraqat S. , Samara Ahmad M. , Sadaqa Wael , Zyoud Sa’ed H.
Published: April 2021

Background

Postoperative nausea and vomiting (PONV) and postoperative pain (POP) are most commonly experienced in the early hours after surgery. Many studies have reported high rates of PONV and POP, and have identified factors that could predict the development of these complications. This study aimed to evaluate the relationship between PONV and POP, and to identify some factors associated with these symptoms.

Methods

This was a prospective, multicentre, observational study performed at An-Najah National University Hospital and Rafidia Governmental Hospital, the major surgical hospitals in northern Palestine, from October 2019 to February 2020. A data collection form, adapted from multiple previous studies, was used to evaluate factors associated with PONV and POP in patients undergoing elective surgery. Patients were interviewed during the first 24 h following surgery. Multiple binary logistic regression was applied to determine factors that were significantly associated with the occurrence of PONV.

Results

Of the 211 patients included, nausea occurred in 43.1%, vomiting in 17.5%, and PONV in 45.5%. Multiple binary logistic regression analysis, using PONV as a dependent variable, showed that only patients with a history of PONV [odds ratio (OR) = 2.28; 95% confidence interval (CI) = 1.03–5.01;p = 0.041] and POP (OR = 2.41; 95% CI = 1.17–4.97;p = 0.018) were significantly associated with the occurrence of PONV. Most participants (74.4%) reported experiencing pain at some point during the first 24 h following surgery. Additionally, the type and duration of surgery were significantly associated with POP (p-values were 0.002 and 0.006, respectively).

Conclusions

PONV and POP are common complications in our surgical patients. Factors associated with PONV include a prior history of PONV and POP. Patients at risk should be identified, the proper formulation of PONV protocols should be considered, and appropriate management plans should be implemented to improve patients’ outcomes.
Association of apolipoproteins A1 and B with type 2 diabetes and fasting blood glucose: a cross-sectional study
Authors: Gao Liang , Zhang Yaju , Wang Xingmin , Dong Hongli
Published: April 2021

Background

Apolipoprotein (Apo) may be associated with type 2 diabetes (T2D), however, little is known whether or not serum apolipoproteins are correlated with fasting blood glucose (FBG) and the prevalence of T2D in Chinese populations. In this study, we examined the association of serum ApoA1, ApoB, and the ratio of ApoB/ApoA1 (ApoB/A1 ratio) with T2D and FBG level, and compared apolipoprotein indicators in predicting T2D in Chinese adults.

Methods

A total of 1027 subjects were enrolled in this cross-sectional study. The association of ApoA1, ApoB, and ApoB/A1 ratio with T2D prevalence was determined using logistic regression models. Multivariate-analysis of covariance (ANCOVA) was performed for comparisons of the mean difference in FBG level.

Results

We found that ApoB and ApoB/A1 ratio were positively associated with T2D prevalence and FBG, while inverse association was noted between ApoA1 and T2D prevalence as well as FBG. Stratified analyses for sex, age, body mass index (BMI), smoking, and alcohol consumption showed no significant difference for the association of ApoA1, ApoB, and ApoB/A1 ratio with the prevalence of T2D among subgroups (all p-interactions> 0.05). Nonetheless, ApoA1 poorly performed in predicting T2D as it provided an AUC value of 0.310 that was significantly lower than those observed for ApoB (AUC value: 0.631) and ApoB/A1 ratio (AUC value: 0.685). Finally, path analyses indicated that the association between ApoB and T2D was mediated by BMI.

Conclusions

This study reveals the association of serum ApoA1, ApoB, and ApoB/A1 ratio with T2D and FBG in Chinese adults, suggesting that ApoB and ApoB/A1 ratio may be early indicators for predicting T2D. Prospective investigation in large cohort is needed.

Published: April 2021

Background

The prevalence of peri-implantitis ranges between 7 and 38.4% depending on risk indicators such as smoking, diabetes mellitus, lack of periodontal maintenance program, and history or presence of periodontitis. Currently, the possible effect of the type of superstructure on peri-implant health is unclear. This cross-sectional study aims to investigate the influence of the superstructure on the prevalence of peri-implant mucositis, peri-implantitis and peri-implant dysbiosis.

Methods

During a 32-month recruitment period dental implants were assessed to diagnose healthy peri-implant tissues, mucositis or peri-implantitis. The study included 1097 implants in 196 patients. Out of all peri-implantitis cases 20 randomly chosen submucosal biofilms from implants with fixed denture (FD) originating from 13 patients and 11 biofilms from implants with removable dentures (RD) originating from 3 patients were studied for microbiome analysis. Composition of transcriptionally active biofilms was revealed by RNAseq. Metatranscriptomic profiles were created for thirty-one peri-implant biofilms suffering from peri-implantitis and microbiome changes associated with superstructure types were identified.

Results

16.41% of the implants were diagnosed with peri-implantitis, 25.00% of implants with RD and 12.68% of implants with FD, respectively. Multivariate analysis showed a significant positive association on patient (p =  < 0.001) and implant level (p = 0.03) between the prevalence of peri-implantitis and RD. Eight bacterial species were associated either with FD or RD by linear discriminant analysis effect size method. However, significant intergroup confounders (e.g. smoking) were present.

Conclusions

Within the limitations of the present work, RDs appear to be a risk indicator for peri-implantitis and seem to facilitate expansion of specific periodontopathogens. Potential ecological and pathological consequences of shift in microbiome from RDs towards higher activity of Fusobacterium nucleatum subspecies animalis and Prevotella intermedia require further investigation.
The relationship between psychosocial distress and oral health status in patients with facial burns and mediation by oral health behaviour

Published: April 2021

Background

There is limited discussion on the influence of psychosocial factors on the oral health of patients with a facial burn injury. This report investigated the relationship between oral health and psychosocial distress in patients with facial burns and the role of oral health behaviour in mediating the relationship.

Methods

The data were part of a cross-sectional study that had systematically and randomly selected patients with > 10% total burn surface area from a burn centre in Pakistan. The oral health status (DMFT, CPI, OHI-S) and severity of facial disfigurement were assessed. Validated instruments in the Urdu language were self-administered and information relating to oral health behaviour (brushing and dental visits), oral health-related quality of life (OHIP-14), satisfaction with appearance, self-esteem, anxiety and depression, resilience, and social support were collected. The statistical analyses included simple linear regression, Pearson correlation, t-test, and ANOVA. Mediation analysis was carried out to examine the indirect effect by oral health behaviour.

Results

From a total of 271 participants, the majority had moderate to severe facial disfigurement (89%), low self-esteem (74.5%), and moderate to high levels of social support (95%). The level of satisfaction with appearance was low, whereas anxiety and depression were high. Disfigurement and satisfaction with appearance were associated with lower self-esteem and social support (p < 0.05). Greater severity of disfigurement, higher levels of anxiety and dissatisfaction with appearance, and lower levels of self-esteem and social support were associated with greater DMFT and OHIP-14 scores, worse periodontal and oral hygiene conditions, and less frequent tooth brushing and dental visits (p < 0.05). The main barriers to oral healthcare utilization were psychological and social issues (p < 0.05). The indirect effect by oral health behaviour was not significant for anxiety but was significant for disfigurement, satisfaction with appearance, self-esteem, and social support.

Conclusion

There is an association between the psychosocial factors and oral health of patients with facial burns through a direct effect and mediation by oral health behaviour.
Effect of body mass index (BMI) on phenotypic features of polycystic ovary syndrome (PCOS) in Singapore women: a prospective cross-sectional study

Published: April 2021

Background

A diagnosis of Polycystic Ovary Syndrome (PCOS) and its related phenotypic features including increased hair growth can affect a woman’s social and emotional well-being. We aim to determine firstly, if excess body weight affects menstrual cycle length, excessive hair growth and other phenotypic features in healthy women without PCOS and secondly, whether having PCOS exacerbates the effects of high body mass index (BMI).

Methods

A prospective cross-sectional study involving healthy women (21–45 years) recruited at an annual health screen for hospital staff and volunteers from the university community, and PCOS cases referred to tertiary gynecological clinics in Singapore. To dissect the independent and/or combinatorial effects of PCOS and BMI on the phenotypic features, subjects were divided into four categories: non-PCOS (normal BMI), non-PCOS (high BMI), PCOS (normal BMI), and PCOS (high BMI). General linear modelling was performed to compare clinical, ovarian, hormonal and metabolic parameters across these four categories.

Results

Of 389 participants, 134 (34.4%) were classified as PCOS and the remaining 255 (65.6%), as the non-PCOS population. Overall 45.2% of women had high BMI (≥ 23). Compared to non-PCOS subjects, women with PCOS had a higher BMI (mean (SD): 25.14 ± 6.46 vs 23.08 ± 4.36, p < 0.001). Women with PCOS and high BMI had increased hair growth with modified Ferriman-Gallwey (mFG) scores that were 2.96-fold higher versus healthy-normal BMI women (mean difference; 1.85, 95% CI 0.80–2.90). Compared to healthy-high BMI women, PCOS women with high BMI had significantly higher mean differences in mFG scores (1.79, 95% CI 0.64–2.93). In PCOS women, having high BMI also significantly increased mFG scores by 1.85-fold (mean difference; 1.82. 95% CI 0.52–3.12). This effect was mirrored by the additive effect of BMI and PCOS on free androgen index. No independent effect of high BMI on rates of oligomenorrhoea, antral follicle count, ovarian volume or serum androgens were observed.

Conclusions

We observed an additive effect of body weight to increase hair growth in women with PCOS. Maximum mFG scores were present in PCOS women with high BMI. Such increases in mFG score may affect the self-esteem of women with PCOS.

Published: April 2021

Background

The use of complementary and alternative medicine (CAM) is increasing worldwide. To the best of knowledge, there is a lack of studies that assess CAM use by Palestinian women during pregnancy. This research aims to determine the prevalence of Palestinian women’s use of CAM during pregnancy, the most frequently used CAM products during the pregnancy period, the main sources that encourage the use of CAM among pregnant women, and the causes of CAM use.

Methods

A descriptive, cross-sectional study was conducted in Palestine using a questionnaire from April 2018 to March 2019. The samples were selected by convenience sampling, including currently pregnant or previously pregnant women in the Obstetrics and Gynecology (OBGYN) clinic at Rafedia Hospital and in primary health care clinics in Nablus city-Palestine. The questionnaire covered socio-demographic variables, health status, types and frequency of CAM used, patients’ sources of information, causes of their usage, attitudes, and beliefs.

Results

Four hundred currently or previously pregnant women participated. Three hundred fifty-five (91.5%) used at least one method of CAM during pregnancy. Most women used at least one method of biologically-based therapies during pregnancy (87.7%). One hundred and one pregnant women (26.7%) utilised at least one type of herb during pregnancy. The most-reported herb used by 12.3% of participants was anise. Of the mind-body therapies, prayer was the most commonly used method during pregnancy (8.3%). Two hundred and sixty-one (65.3%) participants used CAM because they believed CAM was not harmful to them or their babies during pregnancy. Participants gained most of their information about CAM from their families (43.8%) and friends (24.3%). Approximately two-thirds of participants (64.0%) thought that obstetricians should be able to advise on commonly used CAM.

Conclusions

During pregnancy, CAM products are commonly used, and it is important to determine what types are being used by women in Palestine. These findings supplement the body of knowledge on the use of CAM by pregnant women. Pregnancy care providers need to be aware to the familiar types of CAM that women use.
