Abstract
Background
Heart failure (HF) represents an accumulated burden of systemic vascular damage and is the fastest growing form of cardiovascular disease (CVD). Due to increasing HF-attributable mortality rates, we sought to assess the association of the new 2019 Pooled Cohort equations to Prevent Heart Failure (PCP-HF) risk score with CVD and all-cause mortality.

Methods
We linked data for 6333 black and white men and women aged 40–79 years, whom underwent electrocardiographic examination from the Third National Health and Nutrition Exam Survey, to National Death Index record matches. Sex- and race-specific PCP-HF risk scores were calculated using data on age, smoking, body mass index, systolic blood pressure, total cholesterol, HDL-cholesterol, fasting blood glucose, QRS complex duration, and antihypertensive and/or glucose-lowering medications. Cox regression estimated hazard ratios for the association of the PCP-HF risk score with CVD and all-cause mortality.

Results
Individuals were on average 54.9 years old (51.7% women, 25.4% black) and the median 10-year HF risk was 1.6% (Q1 = 0.5, Q3 = 4.8). There were 3178 deaths, 1116 from CVD, over a median follow-up time of 22.3 years. Black women had a higher 10-year HF risk compared to white women (2.1% vs. 1.1%; p < 0.01), while no significant difference was observed in predicted HF risk between black men and white men (2.3% vs. 2.1%, p = 0.16). A two-fold higher PCP-HF risk score was associated with a significant 58% (HR = 1.58; 95% CI, 1.48–1.70; p < 0.0001) and 38% (HR = 1.38; 95% CI, 1.32–1.46; p < 0.0001) greater risk of CVD and all-cause mortality, respectively.

Conclusion
The PCP-HF risk score predicts CVD and all-cause mortality, in addition to the 10-year risk of incident HF among white and black men and women. These results underline the expanded utility of the PCP-HF risk score and suggest that its implementation in the clinical and population health settings may improve primary CVD prevention in the United States.

Abstract
Background
This study aimed to detect Hepatitis B virus (HBV) genome sequences and their variants as of nationwide scale using dried blood spot (DBS) samples and to provide up-to-date reference data for infection control and surveillance in Cambodia.

Method
Among 2518 children age 5–7 years and their 2023 mothers participated in 2017 Cambodia nationwide sero-survey on hepatitis B surface antigen (HBsAg) prevalence using multistage random sampling strategy, 95 mothers and 13 children positive to HBsAg were included in this study. HBV DNA was extracted from DBS, then performed polymerase chain reaction. HBV genotypes and potential variants were examined by partial and full length genomic analysis.

Results
HBsAg positive rate was 4.7% (95/2023) in mothers and 0.52% (13/2518) in their children. Genotype C (80.49%) was abundantly found throughout the whole Cambodia whilst genotype B (19.51%) was exclusively found in regions bordering Vietnam. S gene mutants of HBV were found in 24.29% of mothers and 16.67% of children with HBV DNA positive sera. Full-length genome analysis revealed the homology of 99.62–100% in each mother-child pair. Genotype B was clarified to recombinant genotype B4/C2 and B2/C2. Double (48.39%) and combination mutation (32.26%) were observed in core promoter region of HBV C1 strains.

Conclusions
This study showed the capable of DBS for large-scale molecular epidemiological study of HBV in resource limited countries. Full-genome sequences yield the better understanding of sub-genotypes, their variants and the degree of homology between strains isolated from mother-child pairs calls for effective strategies on prevention, control and surveillance of mother-to-child HBV transmission in Cambodia.

AbstractBackgroundDiphtheria outbreaks occurred in endemic areas and imported and indigenous cases are reported in UE/EEA. Because of the high infectiveness and severity of the disease, early and accurate diagnosis of each suspected case is essential for the treatment and management of the case and close contacts.The aim of the study was to establish simple and rapid testing methods based on Loop-Mediated Isothermal Amplification (LAMP) assay for the detection ofCorynebacterium diphtheriaeand differentiation between toxigenic and non-toxigenic strains.MethodsCorynebacterium diphtheriaeandCorynebacterium ulceransisolates from the National Institute of Public Health-National Institute of Hygiene collection were used for the development of LAMP assay for the diagnosis of diphtheria and nontoxigenicC. diphtheriaeinfections. Various colorimetric methods for visualization of results were investigated. Sensitivity and specificity of the assay were examined using a collection of DNA samples from various gram-positive and gram-negative bacteria.ResultsThe LAMP assay fortoxanddtxRgenes was developed. The sensitivity and specificity of the assay were calculated as 100%. The detection limit was estimated as 1.42 pg/μl concentration of DNA template when the reaction was conducted for 60 min. However, the detection limit was lowered 10 times for every 10 min of reduction in the time of incubation during the reaction. Positive results were successfully detected colorimetrically using hydroxynaphthol blue, calcein, QuantiFluor, and lateral flow Milenia HybriDetect dipsticks.ConclusionThe assay developed in the study might be applied for point-of-care testing of diphtheria and otherC. diphtheriaeinfections as well as for other infections caused by diphtheria-toxin producingCorynebacteriumspecies. It is highly sensitive, specific, inexpensive, easy to use, and suitable for low-resource settings.

Abstract
Background
Clinical manifestations of extraneural infection with the pork tapeworm Taenia solium typically affect the muscles, eyes, alimentary canal, and/or subcutaneous tissues. Children living with HIV are at increased risk for more widespread and severe manifestations of food-borne opportunistic infections, including T. solium, due to fluctuating levels of immunosuppression. We present a case of disseminated T. solium in a HIV-positive child with Kaposi sarcoma living in Tanzania with cysticercosis presenting as widespread subcutaneous nodules.

Case presentation
A 4-year-old HIV-positive boy in Southern Tanzania presented for evaluation of > 30 violaceous skin lesions, few subcutaneous nodules, and a circumferential violaceous penile lesion which rapidly grew after initiation of ART. The patient was clinically diagnosed with Kaposi sarcoma and started on chemotherapy with bleomycin, vincristine, and doxorubicin. He completed 10 cycles of chemotherapy, with full resolution of the violaceous skin and penile lesions but persistence of his subcutaneous nodules, thus paclitaxel was added. After 12 additional cycles of paclitaxel, his subcutaneous nodules enlarged, and biopsy of a scapular subcutaneous nodule was performed. Histopathology revealed a cystic structure with a central larval scolex and serrated spiral canal consistent with T. solium, which confirmed a diagnosis of disseminated cysticercosis. He completed a 10-day course of praziquantel and albendazole with resolution of the subcutaneous nodules.

Conclusions
Disseminated cysticercosis is an unusual opportunistic infection which can present as subcutaneous nodules without other typical cysticercosis symptoms. Immunosuppression – from HIV and/or chemotherapy – may unmask cysticercosis in children in endemic regions and result in more severe manifestations of this disease. Cysticercosis should remain on a clinician’s differential for subcutaneous nodules, especially in children living with HIV. Cysticercosis can mimic Kaposi sarcoma, and histopathology is essential to accurately diagnose and manage patients with concerning skin lesions.

Authors: Zhou Yan , Yang Hong-Yun , Zhang Hui-Li , Zhu Xiao-Jin 
Published: April 2020

Abstract
Background
Abnormal High-density Lipoprotein Cholesterol Concentration is closely related to postoperative acute kidney injury (AKI) after cardiac surgeries. The purpose of this study was to analyze the relationship between High-density Lipoprotein Cholesterol Concentration and acute kidney injury after non-cardiac surgeries.

Method
This was a single-center cohort study for elective non-cardiac non-kidney surgery from January 1, 2012, to December 31, 2017. The endpoint was the occurrence of acute kidney injury (AKI) 7 days postoperatively in the hospital. Preoperative serum High-density Lipoprotein Cholesterol Concentration was examined by multivariate logistic regression models before and after propensity score weighting analysis.

Results
Of the 74,284 surgeries, 4.4% (3159 cases) suffered acute kidney injury. The odds ratio for HDL (0.96–1.14 as reference, < 0.96, 1.14–1.35, > 1.35) was 1.28 (1.14–1.41), P < 0.001; 0.91 (0.80–1.03), P = 0.150; 0.75 (0.64–0.85), P < 0.001, respectively. Using a dichotomized cutoff point for propensity analysis, Preoperative serum HDL <  1.03 mmol/L (> 1.03 as reference) was associated with increased risk of postoperative AKI, with odds ratio 1.40 (1.27 ~ 1.52), P < 0.001 before propensity score weighting, and 1.32 (1.21–1.46), P < 0.001 after propensity score weighting. Sensitivity analysis with other cut values of HDL showed similar results.

Conclusions
Using multivariate regression analyses before and after propensity score weighting, in addition to multiple sensitivity analysis methods, this study found that following non-cardiac surgery, low HDL cholesterol levels were independent risk factors for AKI.

Published: April 2020

Abstract
Background
Radical tracheletomy (RT) with pelvic lymphadenectomy has become an option for young patients with early invasive uterine cervical cancer who desire to maintain their fertility. However, this operative method entails a high risk for the following pregnancy due to its radicality.

Methods
We have performed vaginal RT for 71 patients and have experienced 28 pregnancies in 21 patients. They were followed up carefully according to the follow-up methods we reported previously. Their pregnancy courses and prognoses after the pregnancy were retrospectively reviewed.

Results
All the vaginal RTs were performed safely without serious complications, including 6 patients who underwent the operation during pregnancy. The median time to be pregnant after RT was 29.5 months. 13 patients (46%) became pregnant without artificial insemination by husband or assisted reproductive technology. Cesarean section was performed for all of them. The median time of pregnancy was 34 weeks, and emergent cesarean section was performed for 7 pregnancies (25%). The median birth weight was 2156 g. Four patients had trouble with cervical cerclage, and they suffered from sudden premature preterm rupture of the membrane (pPROM) during the second trimester of pregnancy. We underwent transabdominal cerclage (TAC) for all of them and careful management for the prevention of uterine infection was performed. One patient had a recurrence of cancer during pregnancy.

Conclusions
Both the obstetrical prognosis and oncological prognosis after vaginal RT have become favorable for pregnant patients after vaginal RT.

Authors: Sauer Sandra , Pavel Petra , Schmitt Anita , Cremer Martin , Kriegsmann Mark , Bruckner Thomas , Jordan Karin , Wuchter Patrick , Müller-Tidow Carsten , Kriegsmann Katharina 
Published: April 2020

Abstract
Background
High-dose (HD) chemotherapy followed by autologous blood stem-cell transplantation (ASCT) is the standard treatment for multiple myeloma (MM) patients. However, the collection of sufficient peripheral blood stem cell (PBSC) grafts can be challenging, and the question arises whether reinfusion of low-dose grafts will lead to a hematopoietic recovery.

Methods
The hematopoietic recovery of 148 MM patients who underwent HD melphalan chemotherapy and received PBSC transplants with varying CD34+ cells doses (3–4 × 106 [n = 86], 2–2.5 × 106 [n = 53], < 2 × 106 [n = 9] per kg body weight [bw]) was analyzed in this retrospective single-center study.

Results
All patients reached hematopoietic reconstitution, even those who received < 2 × 106 CD34+ cells/kg bw. 62 (42%) patients received granulocyte-colony-stimulating factor (G-CSF). The median duration to leukocyte recovery ≥1.0 × 109/L was 12 days in every group. The median duration to platelet recovery ≥20 × 109/L was 11, 13 and 13 days, respectively. In the multivariate analysis, a low number of reinfused CD34+ cells was associated with prolonged time until leukocyte reconstitution (p = 0.010, HR 0.607) and platelet recovery (p < 0.001, HR 0.438). G-CSF support significantly accelerated leukocyte (p < 0.001, HR 16.742) but not platelet reconstitution.

Conclusion
In conclusion, reinfusion of low- and even very-low-dose PBSC grafts leads to sufficient hematopoietic reconstitution. No severe adverse events were observed during or after HD chemotherapy and ASCT in the analyzed cohort. While the impact of CD34+ cell dose is marginal, G-CSF significantly accelerates the leukocyte recovery.
Life review therapy for holocaust survivors (LRT-HS): study protocol for a randomised controlled trial
Authors: Forstmeier Simon , van der Hal Elisheva , Auerbach Martin , Maercker Andreas , Brom Danny 
Published: April 2020

Abstract
Background
The Holocaust was one of the most traumatic catastrophes in recorded human history. Survivors seeking psychotherapeutic help today, now in their seventies and older, often show symptoms of a posttraumatic stress disorder (PTSD), depression, or prolonged grief disorder. Established psychological treatments for PTSD (e.g. cognitive behaviour therapy, psychodynamic therapies) have been tested and assessed mainly with young and middle-aged adults; only very few studies examined them in old age. There is no therapy outcome study known to us for any treatment mode for Holocaust survivors. Moreover, there is a need for an age group-specific treatment of PTSD and other stress-related mental disorders. A narrative approach including life-review and narrative exposure seems to meet very well the natural need of older people to review their lives and is highly effective. However, most studies on the efficacy of life review therapy (LRT) focus on late-life depression. There is a lack of efficacy studies evaluating the effect of LRT on PTSD symptoms in older individuals that have experienced traumatic events.

Methods
The main goal of this study is to evaluate the effect of LRT for Holocaust survivors (LRT-HS) on symptoms of PTSD and related mental health problems (depression, anxiety, prolonged grief), compared to a supportive control group. A secondary goal is to identify the characteristics of participants that seem to especially benefit from the treatment. The proposed study is a randomised, controlled follow-up trial including Holocaust survivors with one or more trauma-related disorders. The LRT treatment consists of 20–25 sessions. Before and after the treatment phase, participants in both conditions will be assessed. Follow-up will take place 6 months after the treatment. A sample size of 80 is required (drop-out rate included).

Discussion
Efficacious treatments for trauma-related disorders in older people are of high importance, also because the probability of traumatisation and loss increases with age. Because this study is conducted with this specific group of multiply traumatised people, we are convinced that the results can easily transfer to other samples.

Socioeconomic status and survival after stroke – using mediation and sensitivity analyses to assess the effect of stroke severity and unmeasured confounding
Authors: Lindmark Anita , Norrving Bo , Eriksson Marie 
Published: April 2020

Abstract
Background
Although it has been established that low socioeconomic status is linked to increased risk of death after stroke, the mechanisms behind this link are still unclear. In this study we aim to shed light on the relationship between income level and survival after stroke by investigating the extent to which differences in stroke severity account for differences in survival.

Methods
The study was based on patients registered in Riksstroke (the Swedish stroke register) with first time ischemic stroke (n = 51,159) or intracerebral hemorrhage (n = 6777) in 2009–2012. We used causal mediation analysis to decompose the effect of low income on 3-month case fatality into a direct effect and an indirect effect due to stroke severity. Since causal mediation analysis relies on strong assumptions regarding residual confounding of the relationships involved, recently developed methods for sensitivity analysis were used to assess the robustness of the results to unobserved confounding.

Results
After adjustment for observed confounders, patients in the lowest income tertile had a 3.2% (95% CI: 0.9–5.4%) increased absolute risk of 3-month case fatality after intracerebral hemorrhage compared to patients in the two highest tertiles. The corresponding increase for case fatality after ischemic stroke was 1% (0.4–1.5%). The indirect effect of low income, mediated by stroke severity, was 1.8% (0.7–2.9%) for intracerebral hemorrhage and 0.4% (0.2–0.6%) for ischemic stroke. Unobserved confounders affecting the risk of low income, more severe stroke and case fatality in the same directions could explain the indirect effect, but additional adjustment to observed confounders did not alter the conclusions.

Conclusions
This study provides evidence that as much as half of income-related inequalities in stroke case fatality is mediated through differences in stroke severity. Targeting stroke severity could therefore lead to a substantial reduction in inequalities and should be prioritized. Sensitivity analysis suggests that additional adjustment for a confounder of greater impact than age would be required to considerably alter our conclusions.
Daily almond consumption in cardiovascular disease prevention via LDL-C change in the U.S. population: a cost-effectiveness analysis
Authors: Wang Jifan , Lee Bravatti Michelle A. , Johnson Elizabeth J. , Raman Gowri 
Published: April 2020

Abstract
Background
Heart disease is the leading cause of death in the United States. The U.S. Food and Drug Administration approved the health claim that 1.5 oz (42.5 g) of nut intake may reduce the risk of cardiovascular disease. Previous studies have focused on the cost-effectiveness of other foods or dietary factors on primary cardiovascular disease prevention, yet not in almond consumption. This study aimed to examine the cost-effectiveness of almond consumption in cardiovascular disease primary prevention.

Perspective & Setting
This study assessed the cost-effectiveness of consuming 42.5 g of almond from the U.S. healthcare sector perspective.

Methods
A decision model was developed for 42.5 g of almond per day versus no almond consumption and cardiovascular disease in the U.S. population. Parameters in the model were derived from the literature, which included the probabilities of increasing low-density lipoprotein cholesterol, developing acute myocardial infarction and stroke, treating acute myocardial infarction, dying from the disease and surgery, as well as the costs of the disease and procedures in the U.S. population, and the quality-adjusted life years. The cost of almonds was based on the current price in the U.S. market. Sensitivity analyses were conducted for different levels of willingness-to-pay, the probabilistic sensitivity analysis, ten-year risk prevention, different costs of procedures and almond prices, and patients with or without cardiovascular disease.

Results
The almond strategy had $363 lower cost and 0.02 higher quality-adjusted life years gain compared to the non-almond strategy in the base-case model. The annual net monetary benefit of almond consumption was $1421 higher per person than no almond consumption, when the willingness to pay threshold was set at $50,000 for annual health care expenditure. Almond was more cost-effective than non-almond in cardiovascular disease prevention in all the sensitivity analyses.

Conclusion
Consuming 42.5 g of almonds per day is a cost-effective approach to prevent cardiovascular disease in the short term and potentially in the long term.
