Influence of pre-admission factors on quality of life and adaptation in nursing home residents with dementia: the QOL-EHPAD study protocol
Authors: Villeneuve Roxane , Meillon Céline , Bergua Valérie , Tabue-Teguo Maturin , Amieva Hélène
Published: March 2020

Background

In 2015 in France, 585,560 people were nursing home residents. A large body of studies has identified predictors of poor quality of life and poor adaptation in institution, mostly for residents without dementia. With 42 to 72% of these residents diagnosed with dementia, it is crucial to identify what factors prior to admission might have an impact on quality of life once the admission is finalized, in order to target specific domains of intervention, while the person still lives at home and after his/her admission.

Methods

QOL-EHPAD is a prospective, multi-centred, observational cohort study. At baseline, we will collect retrospective data on the life of 150 persons with dementia and their caregivers. These data will refer to the conditions of admission to a nursing home (emergency admission, involvement in the decision, admission from home or from the hospital) and to the 6 months prior to the admission of the person with dementia: sociodemographic and medical data, psychological tests, information on quality of life, satisfaction, behaviour, and nutrition. Similar data about life in the nursing home will be collected after 6 months, along with information on adaptation of the person with dementia to his/her new living environment. We will use univariate regression analyses followed by stepwise linear regression models to identify which factors pertaining to life at home are associated with quality of life and adaptation after 6 months.

Discussion

This study will provide data on the impact of institutionalization on quality of life and the determinants of a successful institutionalization in people with dementia. This could be helpful in setting up targeted interventions to prepare admission into a nursing home before the actual admission and to accompany both the caregiver and the person with dementia throughout this process.

Authors: Ekman Urban , Ferreira Daniel , Muehlboeck J-Sebastian , Wallert John , Rennie Anna , Eriksdotter Maria , Wahlund Lars-Olof , Westman Eric
Published: March 2020

Background

There remains a lack of large-scale clinical studies of cognitive impairment that aim to increase diagnostic and prognostic accuracy as well as validate previous research findings. The MemClin project will amass large quantities of cross-disciplinary data allowing for the construction of robust models to improve diagnostic accuracy, expand our knowledge on differential diagnostics, strengthen longitudinal prognosis, and harmonise examination protocols across centres. The current article describes the Memory Clinic (MemClin) project’s study-design, materials and methods, and patient characteristics. In addition, we present preliminary descriptive data from the ongoing data collection.

Methods

Nine out of ten memory clinics in the greater Stockholm area, which largely use the same examination methods, are included. The data collection of patients with different stages of cognitive impairment and dementia is coordinated centrally allowing for efficient and secure large-scale database construction. The MemClin project rest directly on the memory clinics examinations with cognitive measures, health parameters, and biomarkers.

Results

Currently, the MemClin project has informed consent from 1543 patients. Herein, we present preliminary data from 835 patients with confirmed cognitive diagnosis and neuropsychological test data available. Of those, 239 had dementia, 487 mild cognitive impairment (MCI), and 104 subjective cognitive impairment (SCI). In addition, we present descriptive data on visual ratings of brain atrophy and cerebrospinal fluid markers.

Conclusions

Based on our current progress and preliminary data, the MemClin project has a high potential to provide a large-scale database of 1200–1500 new patients annually. This coordinated data collection will allow for the construction of improved diagnostic and prognostic models for neurodegenerative disorders and other cognitive conditions in their naturalistic setting.

Authors: de Gennaro Nicolò , Diella Lucia , Monno Laura , Angarano Gioacchino , Milella Michele , Saracino Annalisa
Published: March 2020

Background

Few data are available regarding the use of direct antiviral agents (DAAs) for chronic hepatitis C in psychiatric patients. The aim of the study is to assess safety and outcome of DAAs in patients with psychiatric comorbidities.

Methods

This retrospective, observational, single-centre study enrolled patients treated with psychiatric drugs who initiated DAAs between 2015 and 2018. Patients were classified into two groups: A (on anxiolitycs/antidepressant) and B (on antipsychotics). Week-12 sustained virological response (SVR-12) and adverse events (AEs) were evaluated.

Results

One hundred forty-four patients were included (A:101; B:43). Patients were 49.3% males, mean age 60 years (SD ± 13.5); 31.9% cirrhotic; 125 (86.8%) HCV-monoinfected and 19 (13.2%) HCV /HIV-coinfected. Twenty patients (13.8%) required a change of psychiatric therapy before initiation of DAA. Overall, SVR-12 was achieved in 88.2% of subjects in intention-to-treat(ITT)-analysis. Lower SVR rates were observed in group B vs A (79% vs 92%, p = 0.045) and in those changing psychiatric drugs vs others (8% vs 30%, p = 0.015). According to per-protocol (PP)-analysis, SVR-12 was achieved in 93/95 (97.9%) in group A versus 34/36 (94.4%) in group B (p = 0.30). At least one AE occurred in 60 patients (41.6%), including 10 severe AEs, leading to 3 discontinuations. AEs were more frequently reported in group A (p = 0.015).

Conclusions

The study confirms effectiveness and safety of DAA-based treatment also in this special population, even if a careful evaluation of history and drug-drug interactions is warranted.
Effects of maternal education on birth preparedness and complication readiness among Ethiopian pregnant women: a systematic review and meta-analysis
Authors: Ketema Daniel Bekele , Leshargie Cheru Tesema , Kibret Getiye Dejenu , Assemie Moges Agazhe , Petrucka Pammla , Alebel Animut
Published: March 2020

Background

Birth preparedness and complication readiness are broadly endorsed by governments and international agencies to reduce maternal and neonatal health threats in low income countries. Maternal education is broadly positioned to positively affect the mother’s and her children’s health and nutrition in low income countries. Thus, this systematic review and meta-analysis aims to estimate the effect of maternal education on birth preparedness and complication readiness.

Methods

This review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. We conducted an electronic based search using data bases of PubMed /MEDLINE, Science direct and google scholar. STATA™ Version 14.1 was used to analyze the data, and forest plots were used to present the findings.I2test statistics and Egger’s test were used to assess heterogeneity and publication bias. Pooled prevalence and pooled odd ratios with 95% confidence intervals were computed. Finally, Duval and Tweedie’s nonparametric trim and fill analysis using random-effects meta-analysis was conducted to account for publication bias.

Results

In this meta-analysis, 20 studies involving 13,744 pregnant women meeting the inclusion criteria were included, of which 15 studies reported effects of maternal education on birth preparedness and complication readiness. Overall estimated level of birth preparedness and complication readiness was 25.2% (95% CI 20.0, 30.6%). This meta-analysis found that maternal education and level of birth preparedness and complication readiness were positively associated. Pregnant mothers whose level of education was primary and above were more likely to prepare for birth and obstetric emergencies (OR = 2.4, 95% CI: 1.9, 3.1) than non-educated mothers.

Conclusion

In Ethiopia, the proportion of women prepared for birth and related complications remained low. Maternal education has a positive effect on the level of birth preparedness and complication readiness. Therefore, it is imperative to launch programs at national and regional levels to uplift women’s educational status to enhance the likelihood of maternal health services utilization.
“The midwife helped me ... otherwise I could have died”: women’s experience of professional midwifery services in rural Afghanistan - a qualitative study in the provinces Kunar and Laghman
Authors: Thommesen Trude , Kismul Hallgeir , Kaplan Ian , Safi Khadija , Van den Bergh Graziella
Published: March 2020

Background

Afghanistan has one of the world’s highest maternal mortality ratios, with more than 60% of women having no access to a skilled birth attendant in some areas. The main challenges for childbearing Afghan women are access to skilled birth attendance, emergency obstetric care and reliable contraception. The NGO-based projectAdvancing Maternal and Newborn Health in Afghanistanhas supported education of midwives since 2002, in accordance with the national plan for midwifery education.

The aim of this study is to explore women’s experiences of professional midwifery care in four villages in Afghanistan covered by the project, so as to reveal challenges and improve services in rural and conflict-affected areas of the country.

Methods

An exploratory case-study approach was adopted. Fourteen in-depth interviews and four focus-group discussions were conducted. A total of 39 women participated – 25 who had given birth during the last six months, 11 mothers-in-law and three community midwives in the provinces of Kunar and Laghman. Data generated by the interviews and observations was analysed using thematic content analysis.

Findings

Many of the women greatly valued the trained midwives’ life-saving experience, skills and care, and the latter were important reasons for choosing to give birth in a clinic. Women further appreciated midwives’ promotion of immediate skin-to-skin contact and breastfeeding. However, some women experienced rudeness, discrimination and negligence on the part of the midwives. Moreover, relatives’ disapproval, shame and problems with transport and security were important obstacles to women giving birth in the clinics.

Conclusions

Local recruitment and professional education of midwives as promoted by Afghan authorities and applied in the project seem successful in promoting utilisation and satisfaction with maternal and neonatal health services in rural Afghanistan. Nevertheless, the quality of the services is still lacking, with some women complaining of disrespectful care. There seems to be a need to focus more on communication issues during the education of midwives. An increased focus on in-service training and factors promoting quality care and respectful communication is necessary and should be prioritised.
The relationship between severe maternal morbidity and a risk of postpartum readmission among Korean women: a nationwide population-based cohort study
Authors: Nam Jin Young , Park Eun-Cheol
Published: March 2020

Background

As the rate of cesarean section delivery has increased, the incidence of severe maternal morbidity continues to increase. Severe maternal morbidity is associated with high medical costs, extended length of hospital stay, and long-term rehabilitation. However, there is no evidence whether severe maternal morbidity affects postpartum readmission. Therefore, this study aimed to determine the relationship between severe maternal morbidity and postpartum readmission.

Methods

This nationwide population-based cohort study used the Korean National Health Insurance Service-National Sample cohort of 90,035 delivery cases between January 2003 and November 2013. The outcome variable was postpartum readmission until 6 weeks after the first date of delivery in the hospital. Another variable of interest was the occurrence of severe maternal morbidity, which was determined using the Center for Disease Control and Prevention’s algorithm. The Cox proportional hazard model was used to assess the association between postpartum readmission and severe maternal morbidity after all covariates were adjusted.

Results

The overall incidence of postpartum readmission was 2041 cases (0.95%) of delivery. Women with severe maternal morbidity had an approximately 2.4 times higher risk of postpartum readmission than those without severe maternal morbidity (hazard ratio 2.36, 95% confidence interval 1.75–3.19). In addition, compared with reference group, women who were aged 20–30 years, nulliparous, and delivered in a tertiary hospital were at high risk of postpartum readmission.

Conclusions

Severe maternal morbidity was related to the risk of postpartum readmission. Policy makers should provide a quality indicator of postpartum maternal health care and improve the quality of intrapartum care.
Male involvement in prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, north West Ethiopia, 2018: a cross-sectional study
Authors: Adane Haimanot Abebe , Assefa Nega , Mengistie Bizatu , Demis Asmamaw
Published: March 2020

Background

Globally, male involvement has been identified as a priority target area to be strengthened in the prevention of mother to child transmission (PMTCT) of HIV. However, there are limited studies on husband involvement in the prevention of mother to child transmission of HIV in Ethiopia. Therefore, this study aimed to assess male involvement in the prevention of mother to child transmission of HIV and associated factors among males whose wives gave birth in the last six months before the survey in Enebsiesarmider district, Northwest Ethiopia.

Methods

A Community-based cross-sectional study was employed to assess male involvement in the prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, Northwest Ethiopia. The study was conducted from February 10–30, 2018. A total of 525 participants were involved in the study. A stratified cluster sampling method was used to recruit study participants. Data were collected using a structured interviewer-administered questionnaire. Data were entered using the epi Data software and exported to SPPS for analysis. Descriptive statistics including mean, a proportion were used to describe study variables. Multivariable logistic regression was employed to describe variables with the outcome variable.

Result

Overall male involvement in PMTCT was found to be 26.1% [95%CI, 22.1–29.5]. Respondents who have attended secondary education and above were more likely get involved in PMTCT than who have no formal education [AOR 2.45, 95%CI, 1.47–4.11], Respondents who have good knowledge on PMTCT [AOR 2.57, 95%CI, 1.58–4.18], good knowledge on ANC [AOR 2.10, 95%CI, 1.28–3.44], low cultural barriers [AOR 2.20, 95%CI, 1.34–3.63] low health system barriers [AOR 2.40, 95%CI, 1.37–4.20] were variables that significantly increase male involvement in PMTCT practices.

Conclusion

Male involvement in PMTCT was found to be low in the study area. Therefore, the district health office in collaboration with local health care providers shall design strategies for enhancing male involvement through creating a husband’s knowledge regarding the merit of prevention of mother to child transmission through the provision of adequate information for all male partners at ANC clinic is recommended.
Socioeconomic risk factors for labour induction in the United Kingdom
Authors: Carter Sarah , Channon Amos , Berrington Ann
Published: March 2020

Background

Labour induction is a childbirth intervention experienced by a growing number of women globally each year. While the maternal and socioeconomic indicators of labour induction are well documented in countries like the United States, considerably less research has been done into which women have a higher likelihood of labour induction in the United Kingdom. This paper explores the relationship between labour induction and maternal demographic, socioeconomic, and health indicators by parity in the United Kingdom.

Method

Logistic regression analyses were conducted using the first sweep of the Millennium Cohort Study, including a wide range of socioeconomic factors such as maternal educational attainment, marital status, and electoral ward deprivation, in addition to maternal and infant health indicators.

Results

In fully adjusted models, nulliparous and multiparous women with fewer educational qualifications and those living in disadvantaged places had a greater likelihood of labour induction than women with higher qualifications and women in advantaged electoral wards.

Conclusions

This paper highlights which UK women are at higher risk of labour induction and how this risk varies by socioeconomic status, demonstrating that less advantaged women are more likely to experience labour induction. This evidence could help health care professionals identify which patients may be at higher risk of childbirth intervention.
Validation and modification of staging Systems for Poorly Differentiated Pancreatic Neuroendocrine Carcinoma
Authors: Wang Haihong , Lin Zhenyu , Li Guiling , Zhang Dejun , Yu Dandan , Lin Qili , Wang Jing , Zhao Ye , Pi Guoliang , Zhang Tao
Published: March 2020

Background

The American Joint Committee on Cancer (AJCC) and the European Neuroendocrine Tumor Society (ENETS) staging classifications are two broadly used systems for pancreatic neuroendocrine tumors. This study aims to identify the most accurate and useful tumor–node–metastasis (TNM) staging system for poorly differentiated pancreatic neuroendocrine carcinomas (pNECs).

Methods

An analysis was performed to evaluate the application of the ENETS, 7th edition (7th) AJCC and 8th edition (8th) AJCC staging classifications using the Surveillance, Epidemiology, and End Results (SEER) registry (N = 568 patients), and a modified system based on the analysis of the 7th AJCC classification was proposed.

Results

In multivariable analyses, only the 7th AJCC staging system allocated patients into four different risk groups, although there was no significant difference. We modified the staging classification by maintaining the T and M definitions of the 7th AJCC staging and adopting new staging definitions. An increased hazard ratio (HR) of death was also observed from class I to class IV for the modified 7th (m7th) staging system (compared with stage I disease; HR for stage II =1.23, 95% confidence interval (CI) = 0.73–2.06, P = 0.44; HR for stage III =2.20, 95% CI =1.06–4.56, P = 0.03; HR for stage IV =4.95, 95% CI =3.20–7.65, P < 0.001). The concordance index (C-index) was higher for local disease with the m7th AJCC staging system than with the 7th AJCC staging system.

Conclusions

The m7th AJCC staging system for pNECs proposed in this study provides improvements and may be assessed for potential adoption in the next edition.
Comparison of survival outcomes between radio-chemotherapy and radical hysterectomy with postoperative standard therapy in patients with stage IB1 to IIA2 cervical cancer: long-term oncological outcome analysis in 37 Chinese hospitals
Authors: Liu Ping , Lin Lihong , Kong Yanxiang , Huo Zhifeng , Zhu Lin , Bin Xiaonong , Lang Jinghe , Chen Chunlin
Published: March 2020

Background

This study aimed to compare the survival outcomes of radio-chemotherapy (R-CT) and radical hysterectomy with postoperative standard therapy (RH) in stage IB1-IIA2 cervical cancer patients.

Methods

Based on the large amount of diagnostic and treatment cervical cancer data in China, a real-world study and 1:1 case-control matching were used to compare overall survival (OS) and disease-free survival (DFS) in cervical cancer patients.

Results

In this real-world study, the 5-year OS and DFS in the R-CT group (n = 8949) were lower than those in the RH group (n = 18,152). After applying the inclusion criteria, the OS and DFS in the R-CT group (n = 582) were lower than those in the RH group (n = 4308). After 1:1 case-control matching, the 5-year OS and DFS in the R-CT group (n = 535) were lower than those in the RH group (n = 535) (OS: 76.1% vs. 84.6%, p < 0.001, HR = 1.819; DFS: 75.1% vs. 81.5%, p < 0.001, HR = 1.462, respectively). Further stratification showed that for stage IB1 and IIA1 patients, the 5-year OS and DFS in the R-CT group (n = 300) were lower than those in the RH group (n = 300) (OS: 78.9% vs. 87.0%, p < 0.001, HR = 2.160; DFS: 77.0% vs. 84.9%, p < 0.001, HR = 2.053, respectively). In stage IB2 and IIA2 patients, the 5-year OS in the R-CT group (n = 235) was lower than that in the RH group (n = 235) (72.5% vs. 81.5%, p = 0.039; HR = 1.550), but no difference in the 5-year DFS was found between the two groups (72.6% vs. 76.9%, p = 0.151).

Conclusions

Our study found that for stage IB1-IIA2 cervical cancer patients, RH offers better overall survival and disease-free survival outcomes than R-CT, however, due to the inherent biases of retrospective study, it needs to be confirmed by randomized trials. In addition, we need to further understand the quality of life of the two treatments.

Published: March 2020

Background

50% of Malagasy children have moderate to severe stunting. In 2016, a new 10 year National Nutrition Action Plan (PNAN III) was initiated to help address stunting and developmental delay. We report factors associated with risk of developmental delay in 3 and 4 year olds in the rural district of Ifanadiana in southeastern Madagascar in 2016.

Methods

The data are from a cross-sectional analysis of the 2016 wave of IHOPE panel data (a population-representative cohort study begun in 2014). We interviewed women ages 15–49 using the MICS Early Child Development Indicator (ECDI) module, which includes questions for physical, socio-emotional, learning and literacy/numeracy domains. We analyzed ECDI data using standardized z scores for relative relationships for 2 outcomes: at-risk-for-delay vs. an international standard, and lower-development-than-peers if ECDI z scores were > 1 standard deviation below study mean. Covariates included demographics, adult involvement, household environment, and selected child health factors. Variables significant at alpha of 0.1 were included a multivariable model; final models used backward stepwise regression, clustered at the sampling level.

Results

Of 432 children ages 3 and 4 years, 173 (40%) were at risk for delay compared to international norms and 68 children (16.0%) had lower-development than peers. This was driven mostly by the literacy/numeracy domain, with only 7% of children considered developmentally on track in that domain. 50.5% of children had moderate to severe stunting. 76 (17.6%) had > = 4 stimulation activities in past 3 days.

Greater paternal engagement (OR 1.5 (1.09, 2.07)) was associated with increased delay vs. international norms. Adolescent motherhood (OR. 4.09 (1.40, 11.87)) decreased children’s development vs. peers. Engagement from a non-parental adult reduced odds of delay for both outcomes (OR (95%CI = 0.76 (0.63, 0.91) & 0.27 (0.15, 0 48) respectively). Stunting was not associated with delay risk (1.36 (0.85, 2.15) or low development (0.92 (0.48, 1.78)) when controlling for other factors.

Conclusions

In this setting of high child malnutrition, stunting is not independently associated with developmental risk. A low proportion of children receive developmentally supportive stimulation from adults, but non-parent adults provide more stimulation in general than either mother or father. Stimulation from non-parent adults is associated with lower odds of delay.

Published: March 2020

Background

To carry out a complete clinical, pathological, genetic and microbiological characterization of pediatric patients with molecular confirmed cystic fibrosis (CF) attending the Carlos Andrade Marín Hospital (HCAM) within the study period.

Methods

A cross-sectional analysis of the pediatric population with a confirmed diagnosis of CF disease who attended HCAM, one of the largest tertiary-level hospitals in Ecuador, between 2017 and 2018 was performed. All demographic, clinical and genetic variables were obtained from the electronic medical records (EMR) stored by the hospital.

Results

Forty seven patients with CF were included in the study. Gender distribution was similar between male (48.9%,n = 23) and female patients (51.1%,n = 24). The Tiffeneau-Pinelli index (FEV1/FVC) changed significantly after nine months post-diagnosis (85.55 ± 13.26;p < 0.05). The most common pathogenic genetic variants were F508del, found in 52.78% of the cohort (n = 19); H609R, found in 36.11% (n = 13); g.204099A > C, found in 14.1% (n = 7), followed by G85E and the N1303K with 11.11% (n = 3) each.

Conclusions

To our best knowledge, this is the first study exploring the clinical, genetic and bacteriological profile of CF’s patients in Ecuador. Within the cohort of patients, an important and unique genetic feature was characterized by the presence of the g.204099A > C and the c.206359C > A homozygous polymorphism as well as the presence of the H609R variant, a mutation only reported among Ecuadorians.
Essential fatty acids and Barratt impulsivity in gambling disorder
Authors: Sanchez-Paez Patricia , Perez-Templado Josefa , Saiz-Ruiz Jeronimo , Pastor Oscar , Ibañez Angela
Published: March 2020

Background

Polyunsaturated fatty acids (PUFA) have been long implicated in the etiopathogenesis of mental illnesses, including disorders characterized by high impulsivity. The objective of most of the studies in this field is to determine the effect of omega-3 supplementation on the impulsive symptoms. In contrast, studies analyzing basal PUFA composition in patients with impulsive behaviors are very scarce, results are not yet conclusive, and to date, no publication has specifically evaluated this in gambling disorder. Therefore, the main purpose of this research is to examine the relationship between basal PUFA composition of plasma and erythrocyte membrane and impulsivity in subjects with gambling disorder.

Methods

It is an observational and cross-sectional study. The sample consisted of fifty-five men with gambling disorder, who voluntarily accepted to participate. Basal composition of PUFA in plasma and erythrocyte membrane was assessed by gas chromatography and mass spectrometry. Trait impulsivity was measured by the Barratt Impulsiveness Scale version 11 (BIS-11).

Results

Arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio in the erythrocyte membrane was negatively correlated with total scores in BIS-11. It was also observed that impulsive gamblers had a higher proportion of EPA and a lower value of AA/EPA and AA/docosahexaenoic acid (DHA) ratio in erythrocyte membrane than non-impulsive gamblers.

Conclusions

These results support the hypothesis that alteration of basal PUFA composition exists in disorders characterized by high impulsivity, although the direction of this is still unknown. Unfortunately, the empirical literature on this field is non-existent at the time and we have no direct means to support or refute these outcomes. Further research is needed to determine the relationship between essential fatty acids and disorders characterized by high impulsivity.
Modulating NMDA receptors to treat MK-801-induced schizophrenic cognition deficit: effects of clozapine combining with PQQ treatment and possible mechanisms of action
Authors: Zhou Xingqin , Cai Gangming , Mao Shishi , Xu Dong , Xu Xijie , Zhang Rongjun , Yao Zhiwen
Published: March 2020

Background

Clozapine has remarkable efficacy on both negative and cognitive symptoms of schizophrenia due to its slight activation of NMDA receptor. In fact, much evidence to the contrary. NMDAR is a complex containing specific binding sites, which are regulated to improve negative symptoms and cognitive deficits associated with individuals affected by schizophrenia.

PQQ is a powerful neuroprotectant that specifically binds with NMDA receptors in the brain to produce beneficial physiological and cognitive outcomes. The aim of this study was to enhance NMDAR function and improve cognitive ability in schizophrenia by PQQ combined with clozapine.

Methods

Rats were divided into four groups (n = 5) including control (saline), model (MK-801, 0.5 mg·kg− 1·d− 1), atypical antipsychotic (MK-801 (0.5 mg·kg− 1·d− 1) + Clozapine (1.0 mg·kg− 1·d− 1), and co-agonist NMDA receptor (MK-801 (0.5 mg·kg− 1·d− 1) + Clozapine (0.5 mg·kg− 1·d− 1) + PQQ (1.0 μg·kg− 1·d− 1) group. Each group of rats was injected subcutaneously every day for 6 weeks. Behavior test, including stereotyped behavior, locomotor hyperactivity, learning and memory, was performed. The Western blot assay was performed to analyze the expression of GSK-3β, Akt, NMDAR1, and MGLUR in rat hippocampus.

Results

Results indicated that clozapine and PQQ combination therapy can improve MK801-induced schizophrenia behavior including stereotyped behavior, locomotor hyperactivity and cognitive impairment. Furthermore, we found that modulating NMDA receptors could ameliorate the memory impairments in Mk-801 induced schizophrenia rats by reducing the expression of NMDAR1 and MGLUR3, decreasing hippocampal tau hyperphosphorylation and inhibiting apoptosis through Akt /GSK-3β signaling pathway.

Conclusions

These findings suggest that combination therapy for enhancing NMDA receptors may be able to rescue cognition deficit in schizophrenia. More studies are needed to better elucidate these mechanisms.
Approaches, barriers, and facilitators to abortion-related work in U.S. health departments: perspectives of maternal and child health and family planning professionals
Authors: Berglas Nancy F. , Wingo Erin , Woodruff Katie , Roberts Sarah C. M.
Published: March 2020

Background

Public health agencies in the United States have engaged in abortion-related activities for nearly 50 years. Prior research indicates that, while most state health departments engage in some abortion-related work, their efforts reflect what is required by law rather than the breadth of core public health activities. In contrast, local health departments appear to engage in abortion-related activities less often but, when they do, initiate a broader range of activities.

Methods

This study aimed to: 1) describe the abortion-related activities undertaken by maternal and child health (MCH) and family planning professionals in state and local health departments; 2) understand how health departments approach their programmatic work on abortion, and 3) examine the facilitators and barriers to whether and how abortion work is implemented. Between November 2017 and June 2018, we conducted key informant interviews with 29 professionals working in 22 state and local health departments across the U.S. Interview data were thematically coded and analyzed using an iterative approach.

Results

MCH and family planning professionals described a range of abortion-related activities undertaken within their health departments. We identified three approaches to this work: those mandated strictly by law or policy; those initiated when mandated by law but informed by public health principles (e.g., scientific accuracy, expert engagement, lack of bias, promoting access to care) in implementation; and those initiated by professionals within the department to meet identified needs. More state health departments engaged in activities when mandated, and more local health departments initiated activities based on identified needs. Key barriers and facilitators included political climate, funding opportunities and restrictions, and departmental leadership.

Conclusions

Although state health departments are tasked with implementing legally-required abortion-related activities, some agencies bring public health principles to their mandated work. Efforts are needed to engage public health professionals in developing and implementing best practices around engaging in abortion-related activities.
Culture competence and mental health across different immigrant and refugee groups
Authors: Oppedal Brit , Keles Serap , Cheah Charissa , Røysamb Espen
Published: March 2020

Background

Over the last decades, due to high rates of immigration, many high-income countries have witnessed demographic shifts towards more cultural diversity in the population. Socio-economic deprivation and traumatic experiences pre-migration contribute to a high risk for mental health problems among immigrant background youth. Moreover, when adapting to the multi-cultural contexts of the resettlement countries they face several acculturation demands, which may also affect their mental health in adaptive or hazardous ways. One of these acculturation tasks involves developing the cultural competence necessary to thrive and participate socially within the heritage and the majority cultural domains. From a public mental health perspective, it is important to have thorough knowledge about acculturation-related risk and protective factors. However, this responsibility has been challenged by a lack of acculturation measures that are theoretically linked to mental health, and target the cultural competencies of immigrant background youth. Therefore, the current study aimed at examining if a construct of peer-related culture competence, operationalized in the Youth Culture Competence Scale (YCCS), captured the same competence-phenomenon across different language, age, and immigrant groups in two immigrant-receiving countries. The scale includes two dimensions: one of heritage, and one of majority peer-related culture competence.

Methods

Self-report questionnaire data were collected from 895 unaccompanied refugees and 591 immigrant background high school students in Norway, and from 321 immigrant university students in the United States. To examine if the measure assessed the same phenomenon of peer-related culture competence across these three multi-ethnic samples with an age range from 13 to 28, we examined its measurement equivalence. Additionally, we examined if the association between peer-related culture competence and depressive symptoms was similar in these groups.

Results

Confirmatory factor analyses supported the proposed two factor structure of the YCCS across the three samples. The structural equation model assessing the effects of heritage and majority culture competence on depressive symptoms confirmed that each culture competence dimension had a unique association with depressive symptoms across the samples.

Conclusions

We conclude that the YCCS is a robust acculturation measure that may be included in public health studies of mental health among multi-ethnic refugee and immigrant samples of varied ages.

Background

Chronic Obstructive Pulmonary Disease (COPD) is a progressive and debilitating condition that affects individuals’ quality of life. COPD self-management and supports provided by carers is key to the quality of life people living with COPD. Health literacy (HL) and Patient Activation (PA) are main drivers of self-management practices (SMPs). However, their contribution remains to be fully explored. This study aimed to examine the level of self-management practices, and the relationship with socio-demographic factors, HL and PA among multi-morbid COPD patients from rural Nepal.

Methods

This is a cross-sectional study conducted between July 2018 and January 2019. Patients completed a survey, including Self-management Practices questionnaire (SMPQ), five domains of the Health Literacy Questionnaire (HLQ), and Patient Activation Measure (PAM). The relationship between HL, PAM, and SMPs was examined using univariate statistics. Multivariable analysis was conducted to identify the factors associated with SMPs.

Results

A total of 238 patients responded to the study. The mean score of SMPQ was 45.31(SD = 9.00). The HLQ and PAM scores were positively correlated with the total score of SMPQ. Low level of SMPs were found to be positively associated with being uneducated (β = − 0.43, p = .001), having a low family income (β = − 5.22, p = .002), and, negatively associated with the presence of more than one co-morbidity (β = 3.58, p = 0.007) after controlling for other socio-demographic variables in the multivariable analysis.

Conclusion

The overall SMPs among this sample of Nepalese with COPD were low. Our findings highlight the need to implement a self-management intervention program involving patient activation and health literacy-focused activities for COPD, creating a support system for patients from low-income families and low education.

Background

Infections with Human Papillomavirus (HPV) are the main cause of cervical cancer. Since 2014, the HPV vaccine was introduced in the Brazilian National Vaccination Calendar. The purpose of this study was to assess the knowledge of adolescent girls and their mothers/guardians about HPV and HPV vaccine, identify the factors associated with this knowledge, and evaluate immunization dropout rate.

Methods

This was a cross-sectional study involving adolescent girls and their mothers/guardians. Participants underwent an interview that addressed sociodemographic data, sexual and gynecological history, and knowledge about HPV, HPV vaccine and cervical cancer. The third quartile of the total score was established as a cutoff for assessing knowledge. Adolescents who correctly answered more than four questions and mothers/guardians who obtained more than five correct responses were categorized into high knowledge. Poisson regression analysis was performed to identify variables associated with low knowledge. Vaccination records were used to assess immunization dropout rates. Any adolescent who did not complete the two-dose vaccination schedule was considered dropout.

Results

A total of 666 adolescent girls and 623 mothers/guardians were interviewed. Low knowledge was observed in 76.7% of adolescents and 79.8% of mothers/guardians. Most were unaware of the causal relationship between HPV and cervical cancer, signs and symptoms of HPV infection, and had limited knowledge about the HPV vaccine. Factors associated with low knowledge of adolescents were aged 12 years [IRR 1.2 (95% CI 1. 1-1.3)] or less [IRR 1.3 (95% CI (1. 2-1.4)]; household income lower than US$750 [IRR 1.7 (95% CI 1. 1-2.6)] and household income between US$751 and US$1500 [IRR 1.6 (95% CI 1.0–2.6)]. Among mothers/guardians, low knowledge was related to having completed elementary school or less [IRR 1.5 (95% CI 1. 2-2.0)]; and household income lower than US$750 [IRR 1.2 (95% CI 1.0–1.4)]. Knowledge of adolescents and mothers/guardians was not associated with vaccine uptake. HPV immunization dropout rate was considered high (32.3%).

Conclusion

Knowledge about HPV and cervical cancer as well as vaccine uptake was low. Results highlight the need for educational interventions about HPV and cervical cancer. These actions may contribute to improve adherence to HPV vaccination.

Published: March 2020

Background

The prevalence of non-communicable diseases (NCDs) is increasing in the world. Healthy food choice and adequate physical activity are key factors in preventing NCDs. Food labeling is a strategy that can inform consumers to choose healthier foods at the point of purchase. In this study, we intend to examine the status of existing labels and to clarify their strengths and weaknesses. Then, for the first time in Iran, we will design a type of physical activity equivalent calorie label and will test it on some food groups of packaged products including dairy products, sweetened beverages, cakes, and biscuits.

Methods

This study will be conducted in two phases. In phase 1, nutrition fact labels and traffic light labels will be assessed through focus group discussions and interviews among different groups of mothers, industrialists and nutrition and food industry specialists as to determine strengths and weaknesses of the current labels on packaged products. Then, the initial layout of the physical activity calorie equivalent label will be drawn with respect to the viewpoints received from mothers. Thereafter, we will include the scientific opinions to it for creating the first draft of our new label. In phase 2, a total of 500 mothers of students 6–12 years old randomly assigned to five groups. The study groups will be as follows: (1) without nutrition label group, (2) current traffic light label group, (3) current traffic light label group in which, a brochure will be used to inform mothers, (4) physical activity calorie equivalent label group, and (5) physical activity calorie equivalent label group in which a brochure will be used to inform mothers. Some samples of dairy products, beverages, cakes, and biscuits will be presented. ANOVA and multiple linear regressions will be used to examine the association between the label type and the main consequence (energy of the selected products) and secondary outcome (time).

Discussion

The effect of the new food labels will be evaluated based on the differences between the calories of selected food groups.

Background

Community-acquired pneumonia (CAP) requires urgent and specific antimicrobial therapy. However, the causal pathogen is typically unknown at the point when anti-infective therapeutics must be initiated. Physicians synthesize information from diverse data streams to make appropriate decisions. Artificial intelligence (AI) excels at finding complex relationships in large volumes of data. We aimed to evaluate the abilities of experienced physicians and AI to answer this question at patient admission: is it a viral or a bacterial pneumonia?

Methods

We included patients hospitalized for CAP and recorded all data available in the first 3-h period of care (clinical, biological and radiological information). For this proof-of-concept investigation, we decided to study only CAP caused by a singular and identified pathogen. We built a machine learning model prediction using all collected data. Finally, an independent validation set of samples was used to test the pathogen prediction performance of: (i) a panel of three experts and (ii) the AI algorithm. Both were blinded regarding the final microbial diagnosis. Positive likelihood ratio (LR) values > 10 and negative LR values < 0.1 were considered clinically relevant.

Results

We included 153 patients with CAP (70.6% men; 62 [51–73] years old; mean SAPSII, 37 [27–47]), 37% had viral pneumonia, 24% had bacterial pneumonia, 20% had a co-infection and 19% had no identified respiratory pathogen. We performed the analysis on 93 patients as co-pathogen and no-pathogen cases were excluded. The discriminant abilities of the AI approach were low to moderate (LR+ = 2.12 for viral and 6.29 for bacterial pneumonia), and the discriminant abilities of the experts were very low to low (LR+ = 3.81 for viral and 1.89 for bacterial pneumonia).

Conclusion

Neither experts nor an AI algorithm can predict the microbial etiology of CAP within the first hours of hospitalization when there is an urgent need to define the anti-infective therapeutic strategy.

Published: March 2020

Background

Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder characterized by extraskeletal heterotopic ossification. It is well recognized that FOP can lead to a devastating condition of disability. However, the mortality rate of FOP patients in China and risk factors for mortality are still largely unclear.

Methods

We conducted a retrospective research on a cohort of 65 cases of FOP patients in China from 2008 to 2018. We reviewed medical records of these FOP patients to retrieve information such as date of birth/death, gender, clinical features, genotypes and biochemical parameters and analyze the correlation of these parameters with the mortality.

Results

92.3% (60/65 cases) patients were classic FOP patients, 3.1% (2/65 cases) were FOP-plus and 4.6% (3/65 cases) were FOP variants. 9 cases of this cohort were dead during the ten-year period, and the overall mortality rate was 13.8%. c.617G > A mutation was confirmed in all non-survivors. In FOP patients≤18 years at diagnosis, non-survivors demonstrated significantly lower blood osteocalcin and alkaline phosphatase levels compared with survivors (P < 0.05), and spearman correlation and logistic regression analysis indicated that serum osteocalcin and alkaline phosphatase levels were negatively correlated with the mortality. Furthermore, the receiver-operating characteristic curve analysis showed serum osteocalcin had the largest area under the curve of 0.855 among four biochemical parameters, and serum osteocalcin < 65.9 ng/ml displayed a good capacity to discriminate the non-survivors from survivors in FOP patients aged 18 years and younger at diagnosis.

Conclusions

Our findings showed that the mortality rate of FOP was 13.8% in China. Serum OC level was negatively correlated with the mortality in Chinese FOP patients ≤18 years at diagnosis.
