Published: August 2020

Background

Computed tomography feature tracking (CT-FT) has emerged as a valuable method for the assessment of cardiac function. However, no studies have investigated the usefulness of CT-derived assessments of left ventricular (LV) strain in coronary artery disease (CAD). Our aim was to evaluate regional LV systolic deformation in patients with left anterior descending coronary artery (LAD) stenosis using CT-FT.

Methods

Seventy-six patients with LAD stenosis were enrolled. The patients were divided into four groups according to the percentage of LAD stenosis: ≤25% was defined as group I (24 patients), 26 to 49% as group II (17 patients), 50 to 74% as group III (21 patients), and ≥ 75% as group IV (14 patients). Thirty-two sex- and age-matched healthy subjects were included as controls.

Results

No intergroup differences were found between groups I-IV and the controls in terms of the left ventricular ejection fraction, end-diastolic volume and end-systolic volume. However, the longitudinal strain (LS) of the LAD territory was significantly reduced in groups I-IV compared with the controls (− 20.8, − 18.6%, − 18.6%, and − 17.0% vs − 23.7%, respectively). The circumferential strain (CS) of the LAD territory was significantly reduced in groups III and IV compared with the controls and groups I and II (− 22.4% and − 22.1% vs − 25.4, − 24.1%, and − 25.3%, respectively). Compared with the non-LAD territory, the LAD territory in groups II-IV showed significantly increased LS (− 18.6% vs − 21.9%,p = 0.07; − 18.6% vs − 21.9%,p = 0.024; − 17.5% vs − 20%,p = 0.032, respectively). The severity of LAD stenosis was positively correlated with the LS of the LAD territory (r = 0.438,p = 0.002).

Conclusion

CT-FT can detect decreasing LV systolic function in patients with LAD stenosis. LV regional systolic deformation of the LAD territory was reduced with increasing LAD stenosis severity.

Authors: Teerasarntipan Tongluk , Chaiteerakij Roongruedee , Prueksapanich Piyapan , Werawatganon Duangporn
Published: August 2020

Background

Chronic exposure to lead causes lead to accumulate mainly in the liver. In vivo studies have shown that lead toxicity is related to alterations in the inflammatory response. We aimed to evaluate the association between lead poisoning and liver fibrosis as well as the change in the degree of liver fibrosis, levels of inflammatory mediators and glutathione (GSH) after chelation therapy.

Methods

Workers from a battery factory who were exposed to lead for > 12 months and had a blood lead level (BLL) > 70 μg/dL were enrolled (n = 86) in the study. Participants underwent chelation therapy with intravenous CaNa2EDTA for 2 days followed by treatment with oral D-penicillamine for 90 days. The primary outcome was the change in the degree of liver fibrosis, which was presented as liver stiffness (LS) measured by FibroScan®. Secondary outcomes were the changes in the levels of serum GSH and inflammatory mediators such as tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) after chelation therapy.

Results

Among the 86 participants, there was a positive correlation between the duration of lead exposure and LS (r = 0.249, p = 0.021). To avoid the confounding effect of obesity-related steatosis, only 70 individuals who had controlled attenuation parameters < 296 dB/m, BMI < 25 kg/m2 and normal waist circumference were included in the interventional analysis. After chelation, the mean LS significantly decreased from 5.4 ± 0.9 to 4.8 ± 1.4 kPa (p = 0.001). Similarly, all of the inflammatory cytokines studied significantly decreased after chelation (p < 0.001); TNF-α decreased from 371.6 ± 211.3 to 215.8 ± 142.7; the levels of IL-1β decreased from 29.8 ± 1.7 to 25.9 ± 4.3; and the levels of IL-6 decreased from 46.8 ± 10.2 to 35.0 ± 11.9. On the other hand, the mean GSH level increased significantly from 3.3 ± 3.3 to 13.1 ± 3.7 (p < 0.001) after chelation therapy.

Conclusion

The duration of lead exposure was significantly correlated with the degree of liver fibrosis. Chelation treatment was associated with increased levels of GSH and decreased levels of proinflammatory cytokines and could potentially reduce the degree of LS.

Authors: Abe Tomoyuki , Amano Hironobu , Kobayashi Tsuyoshi , Hanada Keiji , Hattori Minoru , Nakahara Masahiro , Ohdan Hideki , Noriyuki Toshio
Published: August 2020

Background

Postoperative pancreatic fistula (POPF) is a life-threatening postoperative complication. The aim of this study was to evaluate the efficacy of the fistula risk score (FRS) and preoperative body composition factors for predicting the occurrence of clinically relevant POPF (CR-POPF) after pancreaticoduodenectomy (PD).

Methods

In this study, 136 consecutive patients who underwent PD between 2006 and 2018 were enrolled. The risk factors of CR-POPF (grades B and C) were analyzed. Preoperative visceral adipose tissue area (VATA), skeletal mass index (SMI), and subcutaneous adipose tissue area (SATA) were calculated from computed tomography data.

Results

The overall 30-day mortality and morbidity rates were 0.7 and 38%, respectively. The incidence rates of grade B and C CR-POPF were 27 and 4%, respectively. A univariate analysis revealed that male sex, habitual smoking, prognostic nutritional index (PNI) < 45, VATA ≥90, VATA/SATA ≥0.9, VATA/SMI ≥ 1.4, and FRS > 4 were significantly associated with the incidence of CR-POPF. A multivariate analysis revealed that PNI < 45, VATA/SMI ≥ 1.4 and FRS > 4 were the independent risk factors of CR-POPF.

Conclusions

Preoperative anthropomorphic imbalance, PNI, and FRS were independent risk factors for CR-POPF. Patients with high-risk factors should be closely monitored during the postoperative period.

Authors: Huai Pengcheng , Li Furong , Chu Tongsheng , Liu Dianchang , Liu Jian , Zhang Furen
Published: August 2020

Background

Estimating prevalence of Chlamydia trachomatis (CT) worldwide is necessary in designing control programs and allocating health resources. We performed a meta-analysis to calculate the prevalence of CT in the general population.

Methods

The Pubmed and Embase databases were searched for eligible population-based studies from its inception through June 5, 2019. Q test and I2 statistic were used to calculate the heterogeneity between studies. Random effects models were used to pool the prevalence of CT. Meta regression was performed to explore the possible sources of heterogeneity. Publication bias was evaluated using a funnel plot and “trim and fill” method.

Results

Twenty nine studies that reported prevalence of CT infection from 24 countries were identified, including a total population of 89,886 persons. The pooled prevalence of CT among the general population was 2.9% (95% CI, 2.4–3.5%), and females had a higher CT prevalence (3.1, 95% CI, 2.5–3.8%) than males (2.6, 95% CI, 2.0–3.2%) (χ2 = 10.38, P <  0.01). Prevalence of CT was highest in region of America (4.5, 95% CI, 3.1–5.9%), especially in Latin America (6.7, 95% CI, 5.0–8.4%), followed by females in region of Africa (3.8, 95% CI, 0.7–6.9%), while South-East Asia had a lowest CT prevalence 0.8% (95% CI, 0.3–1.3%).

Conclusions

This study provided the updated prevalence of CT among general population worldwide. General population from Latin America, especially females, and women in Africa should be given priority by WHO when design and delivery CT control programs.
The genome-wide supported CACNA1C gene polymorphisms and the risk of schizophrenia: an updated meta-analysis
Authors: Liu Yong-ping , Wu Xue , Xia Xi , Yao Jun , Wang Bao-jie
Published: August 2020

Background

TheCACNA1Cgene was defined as a risk gene for schizophrenia in a large genome-wide association study of European ancestry performed by the Psychiatric Genomics Consortium. Previous meta-analyses focused on the association between theCACNA1Cgene rs1006737 and schizophrenia. The present study focused on whether there was an ancestral difference in the effect of theCACNA1Cgene rs1006737 on schizophrenia. rs2007044 and rs4765905 were analyzed for their effect on the risk of schizophrenia.

Methods

Pooled, subgroup, sensitivity, and publication bias analysis were conducted.

Results

A total of 18 studies met the inclusion criteria, including fourteen rs1006737 studies (15,213 cases, 19,412 controls), three rs2007044 studies (6007 cases, 6518 controls), and two rs4765905 studies (2435 cases, 2639 controls). An allele model study also related rs2007044 and rs4765905 to schizophrenia. The overall meta-analysis for rs1006737, which included the allele contrast, dominant, recessive, codominance, and complete overdominance models, showed significant differences between rs1006737 and schizophrenia. However, the ancestral-based subgroup analysis for rs1006737 found that the genotypes GG and GG + GA were only protective factors for schizophrenia in Europeans. In contrast, the rs1006737 GA genotype only reduced the risk of schizophrenia in Asians.

Conclusions

Rs1006737, rs2007044, and rs4765905 of theCACNA1Cgene were associated with susceptibility to schizophrenia. However, the influence model for rs1006737 on schizophrenia in Asians and Europeans demonstrated both similarities and differences between the two ancestors.
The burden of hyperkalemia in Germany – a real world evidence study assessing the treatment and costs of hyperkalemia
Authors: Haas Jennifer Scarlet , Krinke Kim-Sarah , Maas Christopher , Hardt Thomas , Barck Isabella , Braun Sebastian
Published: August 2020

Background

Hyperkalemia (HK) can affect health outcomes and quality of life, as it is referred to as a potentially life-threatening condition caused by an increased serum potassium concentration in the blood. Patients suffering from heart failure or chronic kidney diseases are at a higher risk of HK, which can further be amplified by the treatment received. To date, data on HK prevalence is lacking for Germany and the aims of this study were to assess HK and compare health-relevant outcomes and healthcare costs between HK patients and non-HK patients.

Methods

The InGef research database containing healthcare claims of over 4 million individuals in Germany was utilized for this retrospective, matched cohort analysis. Patients with non-acute outpatient treated and a subgroup of patients with chronic HK, were identified in 2015 with an individual 1 year pre- and post-index period, taking the first observable HK diagnosis/treatment in 2015 into account as the index event. To identify non-acute outpatient treated HK patients, at least two ICD-10-GM diagnosis codes E87.5 “Hyperkalemia” and/or prescriptions of polystyrene sulfonate were required. Chronic HK patients had additional diagnoses and/or prescriptions in all quarters following the first observable HK diagnosis. Patients without HK were matched 1:1 to the respective HK cohorts.

Results

In the year 2015, 3333 patients with non-acute outpatient treated HK were identified of which 1693 were patients with chronic HK. After matching, 3191 and 1664 HK patients and controls were available for analysis. A significantly higher number of hospitalizations was observed for both HK cohorts in comparison to their matched controls. Dialysis initiation as well as the healthcare costs were higher for both HK cohorts when compared to their matched counterparts.

Conclusions

The disease burden was higher for patients with HK, based on a higher proportion of patients with dialysis initiation and higher healthcare costs.
Impact of physical activity and exercise on bone health in patients with chronic kidney disease: a systematic review of observational and experimental studies
Authors: Cardoso Daniela F. , Marques Elisa A. , Leal Diogo V. , Ferreira Aníbal , Baker Luke A. , Smith Alice C. , Viana João L.
Published: August 2020

Background

Chronic Kidney Disease (CKD) patients frequently develop life-impairing bone mineral disorders. Despite the reported impact of exercise on bone health, systematic reviews of the evidence are lacking. This review examines the association of both physical activity (PA) and the effects of different exercise interventions with bone outcomes in CKD.

Methods

English-language publications in EBSCO, Web of Science and Scopus were searched up to May 2019, from which observational and experimental studies examining the relation between PA and the effect of regular exercise on bone-imaging or -outcomes in CKD stage 3–5 adults were included. All data were extracted and recorded using a spreadsheet by two review authors. The evidence quality was rated using the Cochrane risk of bias tool and a modified Newcastle-Ottawa scale.

Results

Six observational (4 cross-sectional, 2 longitudinal) and seven experimental (2 aerobic-, 5 resistance-exercise trials) studies were included, with an overall sample size of 367 and 215 patients, respectively. Judged risk of bias was low and unclear in most observational and experimental studies, respectively. PA was positively associated with bone mineral density at lumbar spine, femoral neck and total body, but not with bone biomarkers. Resistance exercise seems to improve bone mass at femoral neck and proximal femur, with improved bone formation and inhibited bone resorption observed, despite the inconsistency of results amongst different studies.

Conclusions

There is partial evidence supporting (i) a positive relation of PA and bone outcomes, and (ii) positive effects of resistance exercise on bone health in CKD. Prospective population studies and long-term RCT trials exploring different exercise modalities measuring bone-related parameters as endpoint are currently lacking.
The oncogenic potential of a mutant TP53 gene explored in two spontaneous lung cancer mice models
Authors: Ramelow Julian , Brooks Christopher D. , Gao Li , Almiman Abeer A. , Williams Terence M. , Villalona-Calero Miguel A. , Duan Wenrui
Published: August 2020

Background

Lung cancer is the number one cancer killer worldwide. A major drawback in the lung cancer treatment field is the lack of realistic mouse models that replicate the complexity of human malignancy and immune contexture within the tumor microenvironment. Such models are urgently needed. Mutations of the tumor protein p53 are among the most common alterations in human lung cancers.

Methods

Previously, we developed a line of lung cancer mouse model where mutant human TP53-273H is expressed in a lung specific manner in FVB/N background. To investigate whether the human TP53 mutant has a similar oncogenic potential when it is expressed in another strain of mouse, we crossed the FVB/N-SPC-TP53-273H mice to A/J strain and created A/J-SPC-TP53-273H transgenic mice. We then compared lung tumor formation between A/J-SPC-TP53-273H and FVB/N-SPC-TP53-273H.

Results

We found the TP53-273H mutant gene has a similar oncogenic potential in lung tumor formation in both mice strains, although A/J strain mice have been found to be a highly susceptible strain in terms of carcinogen-induced lung cancer. Both transgenic lines survived more than 18 months and developed age related lung adenocarcinomas. With micro CT imaging, we found the FVB-SPC-TP53-273H mice survived more than 8 weeks after initial detection of lung cancer, providing a sufficient window for evaluating new anti-cancer agents.

Conclusions

Oncogenic potential of the most common genetic mutation, TP53-273H, in human lung cancer is unique when it is expressed in different strains of mice. Our mouse models are useful tools for testing novel immune checkpoint inhibitors or other therapeutic strategies in the treatment of lung cancer.

Published: August 2020

Background

Precision oncology pharmacotherapy relies on precise patient-specific alterations that impact drug responses. Due to rapid advances in clinical tumor sequencing, an urgent need exists for a clinical support tool that automatically interprets sequencing results based on a structured knowledge base of alteration events associated with clinical implications.

Results

Here, we introduced the Oncology Pharmacotherapy Decision Support System (OncoPDSS), a web server that systematically annotates the effects of alterations on drug responses. The platform integrates actionable evidence from several well-known resources, distills drug indications from anti-cancer drug labels, and extracts cancer clinical trial data from the ClinicalTrials.gov database. A therapy-centric classification strategy was used to identify potentially effective and non-effective pharmacotherapies from user-uploaded alterations of multi-omics based on integrative evidence. For each potentially effective therapy, clinical trials with faculty information were listed to help patients and their health care providers find the most suitable one.

Conclusions

OncoPDSS can serve as both an integrative knowledge base on cancer precision medicine, as well as a clinical decision support system for cancer researchers and clinical oncologists. It receives multi-omics alterations as input and interprets them into pharmacotherapy-centered information, thus helping clinicians to make clinical pharmacotherapy decisions. The OncoPDSS web server is freely accessible at https://oncopdss.capitalbiobigdata.com.

Authors: Wu Rensiqin , Zhu Zhifeng , Zhou Dandan
Published: August 2020

Background

It’s necessary to analyze the role of VEGF, apelin, and HO-1 in patients with type 2 diabetes (T2DM), and to evaluate its relevance to diabetic retinopathy (DR).

Methods

T2DM patients who were treated in our hospital from December 1, 2018 to November 30, 2019 were included. T2DM patients were divided into non-DR (NDR) group, non-proliferative DR (NPDR) group, and proliferative DR (PDR) group. and healthy participants were selected as the control group. The value of VEGF, apelin, and HO1 in predicting PDR were analyzed by receiver operating characteristic (ROC) curve, and the relations of VEGF, apelin, HO-1 and clinical factors in PDR patients were analyzed by Pearson correlation analysis.

Results

A total of 295 participants were included. The level of FPG and HbAlc in PDR group were significantly higher than that of other groups (allp < 0.05); the level of VEGF and apelin in PDR group were significantly higher than that of other groups (allp < 0.05), but the level of HO-1 in PDR group were significantly less than that of other groups(p = 0.017); the AUC of VEGF, apelin, HO-1 and combined use was 0.806(95%CI: 0.779–0.861), 0.819(95%CI: 0.765–0.878), 0.808(95%CI: 0.733–0.869) and 0.902(95%CI: 0.822–0.958) respectively, the AUC, sensitivity, specificity of the three combined use was significantly higher than that of single VEGF, apelin, HO-1 use(allp < 0.05). The cutoff values of serum VEGF, apelin, and HO-1 levels for predicting PDR were 163.85 pg/ml, 8.27 ng/ml, and 26.06 mmol/L respectively. Serum VEGF, apelin, and HO-1 in patients with PDR was related to the time course of DM, FPG and HbAlc (allp < 0.05).

Conclusions

VEGF, apelin and HO-1 are related to the progress of DR, and the combined use of VEGF, apelin and HO-1 is beneficial to the diagnosis and treatment of PDR.
Fecal calprotectin as a marker of gastrointestinal involvement in pediatric Henoch–Schönlein purpura patients: a retrospective analysis
Authors: Paek Eun Young , Yi Dae Yong , Kang Ben , Choe Byung-Ho
Published: August 2020

Background

Henoch–Schönlein purpura is a type of systemic vasculitis found in children. Its prognosis is usually good; however, recurrence is relatively common. If the intestines are affected, severe complications could arise. Here, we investigated the value of fecal calprotectin in the early screening of Henoch–Schönlein purpura and as a useful factor for predicting gastrointestinal manifestations.

Methods

We retrospectively reviewed the medical records of pediatric patients who were diagnosed with Henoch–Schönlein purpura and underwent fecal calprotectin testing during the acute phase. The patients were categorized into gastrointestinal involvement and non-gastrointestinal involvement groups based on their clinical symptoms. Moreover, gastrointestinal involvement was categorized as follows: upper gastrointestinal tract involvement (up to the duodenum) and lower gastrointestinal tract involvement (from the terminal ileum).

Results

A total of 69 patients were diagnosed with Henoch–Schönlein purpura and underwent fecal calprotectin testing. Among them, 40 patients (58.0%) showed signs of gastrointestinal involvement. The gastrointestinal involvement group had higher fecal calprotectin levels (379.9 ± 399.8 vs. 77.4 ± 97.6 mg/kg, P = 0.000). There were no significant differences in the recurrence of Henoch–Schönlein purpura symptoms or gastrointestinal symptoms. The cut-off value to identify gastrointestinal involvement was 69.10 mg/kg (P < 0.01). Patients with fecal calprotectin levels of > 50 mg/kg showed more frequent gastrointestinal involvement (77.8% vs. 20.8%, P = 0.000) and more severe gastrointestinal symptoms. Significant differences in abdominal pain duration, Henoch–Schönlein purpura clinical score, and abdominal pain severity were observed (P = 0.002, P = 0.000, and P = 0.000, respectively). Additionally, fecal calprotectin levels were significantly higher in patients with lower gastrointestinal tract involvement (214.67 ± 150.5 vs. 581.8 ± 510.1 mg/kg, P = 0.008), and the cut-off value was 277.5 mg/kg (P < 0.01).

Conclusion

Fecal calprotectin testing is useful for identifying gastrointestinal involvement in pediatric Henoch–Schönlein purpura patients.
“It means so much for me to have a choice”: a qualitative study providing first-person perspectives on medication-free treatment in mental health care
Authors: Oedegaard Christine H. , Davidson Larry , Stige Brynjulf , Veseth Marius , Blindheim Anne , Garvik Linda , Sørensen Jan-Magne , Søraa Øystein , Engebretsen Ingunn Marie Stadskleiv
Published: August 2020

Background

In 2016, the Western Norway Regional Health Authority started to integrate more evidence-based psychosocial interventions into the existing mental health care, emphasizing the right for persons with psychosis to choose medication-free treatment. This change emerged from the debate on the effectiveness and adverse effects of the use of antipsychotic medication. Aspects beyond symptom reduction, such as interpersonal relationships, increased understanding of one’s own pattern of suffering, hope and motivation, are all considered important for the personal recovery process.

Methods

This study explores whether these aspects were present in users’ descriptions of their recovery processes within the medication-free treatment programme in Bergen, Western Norway. We interviewed ten patients diagnosed with psychosis who were eligible for medication-free services about their treatment experiences. Data were analysed using Attride-Stirling’s thematic network approach.

Results

The findings show a global theme relating to personal recovery processes facilitated by the provision of more psychosocial treatment options, with three organizing subthemes: interpersonal relationships between patients and therapists, the patient’s understanding of personal patterns of suffering, and personal motivation for self-agency in the recovery process. Participants described an improved relationship with therapists compared to previous experiences. Integrating more evidence-based psychosocial interventions into existing mental health services facilitated learning experiences regarding the choice of treatment, particularly the discontinuation of medication, and appeared to support participants’ increased self-agency and motivation in their personal recovery processes.

Conclusion

Health care in Norway is perhaps one step closer to optimizing care for people with psychosis, allowing for more patient choice and improving the dialogue and hence the interpersonal relationship between the patient and the therapist. Personal patterns of suffering can be explored within a system aiming to support and have a higher level of acceptance for the discontinuation of medication. Such a system requires personal agency in the treatment regimen, with more focus on personal coping strategies and more personal responsibility for the recovery process.
The engagement of psychiatrists in the assessment of euthanasia requests from psychiatric patients in Belgium: a survey study
Authors: Verhofstadt Monica , Audenaert Kurt , Van den Broeck Kris , Deliens Luc , Mortier Freddy , Titeca Koen , Pardon Koen , De Bacquer Dirk , Chambaere Kenneth
Published: August 2020

Background

Since its legalisation in 2002, the number of times euthanasia has been carried out in response to requests from adults with psychiatric conditions (APC) has continued to increase. However, little is known about why and how psychiatrists become engaged in the assessment of such euthanasia requests.

Methods

A cross-sectional survey study was conducted between November 2018 and April 2019 of 499 psychiatrists affiliated with the Flemish Psychiatry Association. Chi square/Fisher’s exact tests were performed to examine if, and to what extent, psychiatrists’ backgrounds relate to their concrete experiences. The answers to the open question regarding motives for (non-) engagement were thematically coded.

Results

Two hundred one psychiatrists participated, a response rate of 40%. During their careers, 80% of those responding have been confronted with at least one euthanasia request from an APC patient and 73% have become involved in the assessment procedure. Their engagement was limited to the roles of: referring physician (in 44% of the psychiatrists), attending physician (30%), legally required ‘advising physician’ (22%), and physician participating in the actual administration of the lethal drugs (5%). Within the most recent 12 months of practice, 61% of the respondents have been actively engaged in a euthanasia assessment procedure and 9% have refused at least once to be actively engaged due to their own conscientious objections and/or the complexity of the assessment. The main motive for psychiatrists to engage in euthanasia is the patient’s fundamental right in Belgian law to ask for euthanasia and the psychiatrist’s duty to respect that. The perception that they were sufficiently competent to engage in a euthanasia procedure was greater in psychiatrists who have already had concrete experience in the procedure.

Conclusions

Although the majority of psychiatrists have been confronted with euthanasia requests from their APC patients, their engagement is often limited to referring the request to a colleague physician for further assessment. More research is needed to identify the determinants of a psychiatrist’s engagement in euthanasia for their APC patients and to discover the consequences of their non-, or their restricted or full engagement, on both the psychotherapeutic relationship and the course of the euthanasia request.
Identification of risk factors for involuntary psychiatric hospitalization: using environmental socioeconomic data and methods of machine learning to improve prediction
Authors: Karasch O. , Schmitz-Buhl M. , Mennicken R. , Zielasek J. , Gouzoulis-Mayfrank E.
Published: August 2020

Background

The purpose of this study was to identify factors associated with a high risk of involuntary psychiatric in-patient hospitalization both on the individual level and on the level of mental health services and the socioeconomic environment that patients live in.

Methods

The present study expands on a previous analysis of the health records of 5764 cases admitted as in-patients in the four psychiatric hospitals of the Metropolitan City of Cologne, Germany, in the year 2011 (1773 cases treated under the Mental Health Act and 3991 cases treated voluntarily). Our previous analysis had included medical, sociodemographic and socioeconomic data of every case and used a machine learning-based prediction model employing chi-squared automatic interaction detection (CHAID). Our current analysis attempts to improve the previous one through (1) optimizing the machine learning procedures (use of a different type of decision-tree prediction model (Classification and Regression Trees (CART) and application of hyperparameter tuning (HT)), and (2) the addition of patients’ environmental socioeconomic data (ESED) to the data set.

Results

Compared to our previous analysis, model fit was improved. Main diagnoses of an organic mental or a psychotic disorder (ICD-10 groups F0 and F2), suicidal behavior upon admission, admission outside of regular service hours and absence of outpatient treatment prior to admission were confirmed as powerful predictors of detention. Particularly high risks were shown for (1) patients with an organic mental disorder, specifically if they were retired, admitted outside of regular service hours and lived in assisted housing, (2) patients with suicidal tendencies upon admission who did not suffer from an affective disorder, specifically if it was unclear whether there had been previous suicide attempts, or if the affected person lived in areas with high unemployment rates, and (3) patients with psychosis, specifically those who lived in densely built areas with a large proportion of small or one-person households.

Conclusions

Certain psychiatric diagnoses and suicidal tendencies are major risk factors for involuntary psychiatric hospitalization. In addition, service-related and environmental socioeconomic factors contribute to the risk for detention. Identifying modifiable risk factors and particularly vulnerable risk groups should help to develop suitable preventive measures.

Authors: Vahedian-Azimi Amir , Moayed Malihe Sadat , Rahimibashar Farshid , Shojaei Sajad , Ashtari Sara , Pourhoseingholi Mohamad Amin
Published: August 2020

Background

Coronavirus disease 2019 (COVID-19) pandemic has caused serious psychological problems, including panic attack, anxiety, stress, and depression. The main objective of this study was to measure the prevalence and compare the severity of this psychological distress among four groups of an Iranian population.

Method

In a cross-sectional survey, the mental health status of four groups of an Iranian society including community population, patients with COVID-19, medical staff, and medical students were investigated by the self-report questionnaire of Depression, Anxiety, and Stress Scale (DASS). DASS-21 questionnaire and the demographic data sheet were filled out by the participants. All statistical analyses were done using R version 3.6.1 software. P-values less than 0.05 were considered as statistically significant. ANOVA test was used to compare the severity of stress, anxiety, and depression between the four study groups.

Results

Of the 886 participants in this survey, 554 (62.5%) were men and 332 (37.5%) were women, and the mean ± standard division of age was 40.91 ± 10.7 years. Among these participants, 241 (27.2%) were selected from community population, 221 (24.9%) were patients with COVID-19, 217 (24.5%) were medical staff, and 207 (23.4%) were medical students. The mean score of stress, anxiety, and depression in medical students and patients with COVID-19 was significantly higher than in medical staff and community population (P < 0.05). Overall, the anxiety score in men was higher than that in women (27.4 ± 4.6 vs. 26.48 ± 4.8, P = 0.006), and unmarried participants had a significantly higher depression score compared with the married group (27.5 ± 4.8 vs. 26.7 ± 4.6, P = 0.023). In addition, the score of depression was higher in female medical staff (27.08 ± 4.6 vs. 25.33 ± 4.3, P = 0.011) and community population (26.6 ± 4.3 vs. 25.3 ± 4.3, P = 0.02) than in male.

Conclusion

COVID-19 patients and medical students in contact with these patients were at a high risk for mental illness due to lower experience compared with professional medical staff and community population. Continuous surveillance and monitoring of psychological distress for outbreaks should become a routine part of preparedness efforts worldwide.

Background

Multicomponent workplace-based interventions aimed at reducing sitting time among office workers are becoming increasingly popular. ‘Take a Stand!’ was such an intervention, reducing sitting time by 71 min after 1 month and 48 min after 3 months. However, it is unclear how the implementation process of ‘Take a Stand!’ affected these results. The present study explored how individual factors and organizational context influenced implementation and effect in ‘Take a Stand!’

Methods

This was a mixed-methods study, combining data from interviews, questionnaires and accelerometers. Directed content analysis was used for analysing interviews with participants, ambassadors and managers from the 10 intervention offices in the ‘Take a Stand!’ study. Categories for analysis were taken fromFramework for Evaluating Organizational-level Interventions. Interview data were combined with questionnaire and activity data, and multilevel analysis was undertaken to assess how changes in sitting time varied depending on the assessed factors. In addition, interview data were used to underpin results from the multilevel analysis.

Results

Concurrent institutional changes were found to be a barrier for the intervention by ambassadors, while participants and managers did not find it to be an issue. Management support was consistently highlighted as very important. Participants evaluated ambassadors as being generally adequately active but also, that the role had a greater potential.

The motivational and social aspects of the intervention were considered important for the effect. This was supported by regression analyses, which showed that a strong desire to change sitting time habits, strong motivation towards the project, and a high sense of collective engagement were associated to less sitting time at 3 months of about 30 min/8 h working day compared to participants with low scores. Influence from other participants (e.g. seeing others raise their tables) and the use of humour were continuously highlighted by participants as positive for implementation. Finally, the intervention was found to influence the social climate at the workplace positively.

Conclusion

Individual motivation was related to the sitting time effect of ‘Take a Stand!’, but the organizational culture was relevant both to the implementation and effect within the office community. The organizational culture included among others to ensure general participation, to uphold management and peer-support, and maintain a positive environment during the intervention period.

Background

There is increasing evidence linking environmental tobacco smoke (ETS) exposure at homes to the development of asthma among adolescents. Few studies have addressed this issue in the Middle Eastern countries including Kuwait. Therefore, this cross-sectional study assessed the prevalence of ETS exposure at home, prevalence of asthma and other respiratory conditions and examined the ETS exposure at home and personal tobacco smoking as risk factors for self-reported asthma among high-school students in Kuwait.

Methods

In this cross-sectional study, we enrolled participants from nine high-schools of Hawally Governorate of Kuwait during October 2015. We adapted a previously validated self-administered questionnaire for data collection. Prevalence of self-reported asthma and ETS exposure (≥ 1 smoker at home vs. none) were computed. The association between exposures of interest and self-reported asthma status was examined using a multivariable log-binomial regression model.

Results

Of 800 enrolled participants, 746 (92.2%) consented and completed the questionnaire. The participants with mean (SD) age of 16.8 (0.68) years were predominantly Kuwaiti (74.8%) and female (50.1%). The prevalence of ETS exposure at home and personal current smoking was 54 and 12.4% respectively. Self-reported asthma prevalence was 20.5%. Furthermore, the prevalence of physician-diagnosed asthma, wheezing during the last 12 months and wheezing ‘ever’ was 16.4, 20.1 and 26.2%, respectively. Fitted multivariable log-binomial regression model revealed that compared with the non-asthmatic, participants with self-reported asthma tended to be current smokers (adjusted prevalence ratio (adjusted PR) = 1.82; 95% CI: 1.30–2.56; p = 0.001) or have had ETS exposure at home (adjusted PR = 1.64; 95% CI: 1.21–2.23; p = 0.002).

Conclusions

We recorded a high prevalence of ETS exposure at home, high prevalence of self-reported asthma and identified ETS exposure at home and being a current smoker as strong risk factors for self-reported asthma among adolescents. Voluntary household smoking bans may substantially minimize the ETS exposure among adolescents. Additionally, such restriction may inculcate an antismoking attitude and prevent smoking initiation among adolescents. Such efforts may bring about reduction in ETS exposure and associated asthma risk and other smoking-related morbidities in this and other similar settings.

Background

Asthma control is influenced by multiple factors. These factors must be considered when appraising asthma interventions and their effectiveness in the Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates [UAE]). Based on published studies, the most prevalent asthma treatment in these countries are fixed dose combinations (FDC) of inhaled corticosteroid and long-acting beta-agonist (ICS/LABA). This study is a rapid review of the literature on: (a) factors associated with asthma control in the GCC countries and (b) generalisability of ICS/LABA FDC effectiveness studies.

Methods

To review local factors associated with asthma control and, generalisability of published ICS/LABA FDC studies, two rapid reviews were conducted. Review 1 targeted literature pertaining to asthma control factors in GCC countries. Eligible studies were appraised, and clustering methodology used to summarise factors. Review 2 assessed ICS/LABA FDC studies in conditions close to actual clinical practice (i.e. effectiveness studies). Eligibility was determined by reviewing study characteristics. Evaluation of studies focused on randomised controlled trials (RCTs). In both reviews, initial (January 2018) and updated (November 2019) searches were conducted in EMBASE and PubMed databases. Eligible studies were appraised using the Critical Appraisal Skills Program (CASP) checklists.

Results

We identified 51 publications reporting factors associated with asthma control. These publications reported studies conducted in Saudi Arabia (35), Qatar (5), Kuwait (5), UAE (3), Oman (1) and multiple countries (2). The most common factors associated with asthma control were: asthma-related education (13 articles), demographics (11articles), comorbidities (11 articles) and environmental exposures (11 articles). Review 2 identified 61 articles reporting ICS/LABA FDC effectiveness studies from countries outside of the GCC. Of these, six RCTs were critically appraised. The adequacy of RCTs in informing clinical practice varied when appraised against previously published criteria.

Conclusions

Asthma-related education was the most recurring factor associated with asthma control in the GCC countries. Moreover, the generalisability of ICS/LABA FDC studies to this region is variable. Hence, asthma patients in the region, particularly those on ICS/LABA FDC, will continue to require physician review and oversight. While our findings provide evidence for local treatment guidelines, further research is required in GCC countries to establish the causal pathways through which asthma-related education influence asthma control for patients on ICS/LABA FDC therapy.

Background

Low uptake of sexually transmitted infection testing by sexually active young people is a worldwide public health problem. Screening in non-medical settings has been suggested as a method to improve uptake. The “Test n Treat” feasibility trial offered free, on-site rapid chlamydia/gonorrhoea tests with same day treatment for chlamydia (and gonorrhoea treatment at a local clinic,) to sexually active students (median age 17 years) at six technical colleges in London. Despite high rates of chlamydia (6% prevalence), uptake of testing was low (< 15%). In a qualitative study we explored the acceptability, including barriers and facilitators to uptake, of on-site chlamydia screening.

Methods

In 2016–17 we conducted a qualitative study in the interpretative tradition using face to face or telephone semi-structured interviews with students (n = 26), teaching staff (n = 3) and field researchers (n = 4). Interviews were digitally recorded, transcribed and thematically analysed.

Results

From the student perspective, feelings of embarrassment and the potential for stigma were deterrents to sexually transmitted infection testing. While the non-medical setting was viewed as mitigating against stigma, for some students volunteering to be screened exposed them to detrimental judgements by their peers. A small financial incentive to be screened was regarded as legitimising volunteering in a non-discrediting way. Staff and researchers confirmed these views. The very low level of knowledge about sexually transmitted infections influenced students to not view themselves as candidates for testing. There were also suggestions that some teenagers considered themselves invulnerable to sexually transmitted infections despite engaging in risky sexual behaviours. Students and researchers reported the strong influence peers had on uptake, or not, of sexually transmitted infection testing.

Conclusions

This study offers new insights into the acceptability of college-based sexually transmitted infection screening to young, multi-ethnic students. Future studies in similar high risk, hard to reach groups should consider linking testing with education about sexually transmitted infections, offering non stigmatising incentives and engaging peer influencers.
Work-related moderators of the relationship between organizational change and sickness absence: a longitudinal multilevel study

Published: August 2020

Background

A sizeable body of research has demonstrated a relationship between organizational change and increased sickness absence. However, fewer studies have investigated what factors might mitigate this relationship. The aim of this study was to examine if and how the relationship between unit-level downsizing and sickness absence is moderated by three salient work factors: temporary contracts at the individual-level, and control and organizational commitment at the work-unit level.

Methods

We investigated the association between unit-level downsizing, each moderator and both short- and long-term sickness absence in a large Norwegian hospital (n = 21,085) from 2011 to 2016. Data pertaining to unit-level downsizing and employee sickness absence were retrieved from objective hospital registers, and moderator variables were drawn from hospital registers (temporary contracts) and the annual work environment survey (control and organizational commitment). We conducted a longitudinal multilevel random effects regression analysis to estimate the odds of entering short- (< = 8 days) and long-term (> = 9 days) sickness absence for each individual employee.

Results

The results showed a decreased risk of short-term sickness absence in the quarter before and an increased risk of short-term sickness absence in the quarter after unit-level downsizing. Temporary contracts and organizational commitment significantly moderated the relationship between unit-level downsizing in the next quarter and short-term sickness absence, demonstrating a steeper decline in short-term sickness absence for employees on temporary contracts and employees in high-commitment units. Additionally, control and organizational commitment moderated the relationship between unit-level downsizing and long-term sickness absence. Whereas employees in high-control work-units had a greater increase in long-term sickness absence in the change quarter, employees in low-commitment work-units had a higher risk of long-term sickness absence in the quarter after unit-level downsizing.

Conclusions

The results from this study suggest that the relationship between unit-level downsizing and sickness absence varies according to the stage of change, and that work-related factors moderate this relationship, albeit in different directions. The identification of specific work-factors that moderate the adverse effects of change represents a hands-on foundation for managers and policy-makers to pursue healthy organizational change.
