Relationships Between Managerial and Organizational Practices, Psychological Health at Work, and Quality of Care in Pediatric Oncology.

PURPOSE Psychological health at work for care providers is an important issue, because they are directly involved in quality of patient care. Managerial and organizational determinants have been found to be indicators of psychological health at work. The main objective of this study was to explore the relationships between the psychological health at work of pediatric oncology care workers with managerial and organizational determinants and with quality of care. MATERIALS AND METHODS We performed regression analysis between psychological health at work (quality of work life [QWL], job satisfaction, and so on), managerial determinants (transformational leadership, perceived autonomy support), organizational determinants (organizational support, organizational justice, and participatory approach), and perceived quality of care. RESULTS Participants were 510 health care professionals working in French pediatric oncology centers. No significant differences in the psychological health at work of the participants were found based on age, sex, length of employment, or professional discipline. In simple regression, significant associations were found between psychological health at work with all managerial and organizational determinants. In multiple regression, a significant link was found between QWL and perceived organizational support (β = .21; P < .001), organizational justice (β = .20, P < .001), and overall participatory approach (β = .10; P < .02). Job satisfaction was also related to perceived organizational support (β = .16; P < .01). Finally, perceived quality of care was linked to QWL (β = .15; P < .01) and job satisfaction (β = .30; P < .001). CONCLUSION These results emphasize the importance of the role of managers and the organization in psychological health at work of health care providers and also in the quality of patient care.
Ezrin is essential for the entry of Japanese encephalitis virus into the human brain microvascular endothelial cells

ABSTRACT Japanese encephalitis virus (JEV) remains the predominant cause of viral encephalitis worldwide. It reaches the central nervous system upon crossing the blood–brain barrier through pathogenic mechanisms that are not completely understood. Here, using a high-throughput siRNA screening assay combined with verification experiments, we found that JEV enters the primary human brain microvascular endothelial cells (HBMEC) through a caveolae-mediated endocytic pathway. The role of ezrin, an essential host factor for JEV entry based on our screening, in caveolae-mediated JEV internalization was investigated. We observed that JEV internalization in HBMEC is largely dependent on ezrin-mediated actin cytoskeleton polymerization. Moreover, Src, a protein predicted by a STRING database search, was found to be required in JEV entry. By a variety of pharmacological inhibition and immunoprecipitation assays, we found that Src, ezrin, and caveolin-1 were sequentially activated and formed a complex during JEV infection. A combination of in vitro kinase assay and subcellular analysis demonstrated that ezrin is essential for Src-caveolin-1 interactions. In vivo, both Src and ezrin inhibitors protected ICR suckling mice against JEV-induced mortality and diminished mouse brain viral load. Therefore, JEV entry into HBMEC requires the activation of the Src-ezrin-caveolin-1 signalling axis, which provides potential targets for restricting JEV infection.
Combined Effects of Single Nucleotide Polymorphisms (SNPs) within C-reactive Protein (CRP) and Environmental Parameters on Risk and Prognosis for Diabetic Foot Osteomyelitis Patients

Abstract Purpose This study was aimed to discover the combined effects of single nucleotide polymorphisms (SNPs) within the C-reactive protein (CRP) gene and potential environmental factors on the risk and prognosis for diabetic foot osteomyelitis (DFO). Methods A total of 1734 diabetes mellitus patients, 681 with DFO and 1053 without DFO, were successfully recruited, as well as 1261 healthy control individuals. Participants data were recorded regarding age, gender, smoking and drinking history, body mass index (BMI), hypertension, cacosmia, and ulceration. A total of 11 SNPs within the CRP gene were designated for exploration, by logistic regression analyses, of how they might interact with environmental factors to affect susceptibility to DFO. Results Frequencies of smoking and drinking, and incidence of hypertension, cacosmia, or ulceration displayed marked differences (all P<0.05) between DFO and non-DFO patients. Furthermore, allele G of rs11265260 (A>G), allele G of rs1800947 (C>G), and allele T of rs3093059 (T>C) and rs1130864 (C>T) exhibited a trend to increase risk of DFO (all P<0.05). Allele G of rs11265260 (A>G), allele G of rs1800947 (C>G) and rs3093068 (G>C), and allele T of rs1130864 (C>T) were significant predictors of poor prognosis among DFO patients (P<0.05). In addition, genotypes of rs11265260 (i.e., GG and AG), rs1800947 (i.e., CG and GG), rs3093059 (i.e., TT) and rs113084 (i.e., CT and TT) amplified the influence of smoking, alcohol consumption, cacosmia, and ulceration on progression from non-DFO to DFO (all γ>1). Conclusion Genetic mutations within CRP functioned interactively with external factors to affect DFO risk.
Genotoxic risk in health-care professionals occupationally exposed to low doses of ionizing radiation

The purpose of this study was to evaluate the potential influence of occupational ionizing radiation (IR) exposure on health professionals, assessing DNA damage using the comet and micronucleus (MN) assays and analyzing relative risks, correlations, and associated factors between outcomes and socioeconomic and lifestyle factors. Blood and buccal samples were collected from 36 workers, who actively participated in an imaging sector of a hospital, who were either exposed to IR directly or indirectly (9 internal control and 27 exposed), and 27 individuals living in the same city but with no occupational exposure (external control, unexposed/healthy). All radiation dosages performed on the 36 workers were less than 20 mSv/y, not exceeding the effective dose limit for occupational exposure. A questionnaire identified socioeconomic and lifestyle factors associated with the outcomes. The results of the MN assay showed a significant difference between both internal control and the exposed group when compared to the external control. For the comet assay, there were significant differences between the percent of tail DNA of the exposed group and external controls, but no difference was found between the exposed group and internal controls. Relative risk associations were found in time of exposure, hours worked per week, and perceived stress. Correlations were found between the outcomes and age, consumption of alcohol, and frequencies of X-rays during life. Variables that showed to be significant in the adjusted analysis were skin color and recent exposure to radiation. Albeit limited, the findings of this study suggest genotoxicity in both blood and buccal mucosa cells of workers exposed directly or indirectly to IR and that lifestyle and socioeconomic factors are associated and correlated with the risk of developing these outcomes.
Clinical features and prognostic factors for extracranial oligometastatic breast cancer in China

Evidence of an oligometastatic state in metastatic breast cancer (MBC) is relatively limited. The aim of our study was to investigate the clinical features and prognostic factors for extracranial oligometastatic breast cancer and to identify the best treatment approaches in this select population. Fifty postoperative inpatients diagnosed with extracranial oligometastatic breast cancer at the National Cancer Center in China between 2009 and 2014 were consecutively enrolled. Oligometastatic breast cancer was defined as MBC with three or fewer metastatic lesions confined to one organ; de novo Stage IV disease and local‐regional recurrence were excluded. The median progression‐free survival (PFS) and overall survival (OS) times were 15.2 and 78.9 months, respectively, and the 2‐year PFS and 5‐year OS rates were 40% and 58%, respectively. First‐line treatment approach with standard systemic treatment + surgical resection for all metastatic lesions was an independent prognostic factor for prolonged PFS (hazard ratio = 0.32; 95% confidence interval [CI], 0.14‐0.73; P = .006) and OS (hazard ratio = 0.35; 95% CI, 0.14‐0.86; P = .022). Subgroup analysis showed that patients with a disease‐free interval (DFI) ≥24 months, one metastatic lesion or the hormone receptor (HR) + subtype were more likely to get benefit from resection. Patients with oligometastatic breast cancer have a relatively good prognosis. Surgical resection for metastatic lesions could significantly improve PFS and OS. Further prospective research is warranted to confirm the results and to develop biomarkers for better patient selection.
Challenging the negative learning bias hypothesis of depression: reversal learning in a naturalistic psychiatric sample

Abstract Background Classic theories posit that depression is driven by a negative learning bias. Most studies supporting this proposition used small and selected samples, excluding patients with comorbidities. However, comorbidity between psychiatric disorders occurs in up to 70% of the population. Therefore, the generalizability of the negative bias hypothesis to a naturalistic psychiatric sample as well as the specificity of the bias to depression, remain unclear. In the present study, we tested the negative learning bias hypothesis in a large naturalistic sample of psychiatric patients, including depression, anxiety, addiction, attention-deficit/hyperactivity disorder, and/or autism. First, we assessed whether the negative bias hypothesis of depression generalized to a heterogeneous (and hence more naturalistic) depression sample compared with controls. Second, we assessed whether negative bias extends to other psychiatric disorders. Third, we adopted a dimensional approach, by using symptom severity as a way to assess associations across the sample. Methods We administered a probabilistic reversal learning task to 217 patients and 81 healthy controls. According to the negative bias hypothesis, participants with depression should exhibit enhanced learning and flexibility based on punishment v. reward. We combined analyses of traditional measures with more sensitive computational modeling. Results In contrast to previous findings, this sample of depressed patients with psychiatric comorbidities did not show a negative learning bias. Conclusions These results speak against the generalizability of the negative learning bias hypothesis to depressed patients with comorbidities. This study highlights the importance of investigating unselected samples of psychiatric patients, which represent the vast majority of the psychiatric population.
Prognostic Factors for Severe Coronavirus Disease 2019 in Daegu, Korea

Background Since its first detection in December 2019, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 infection has spread rapidly around the world. Although there have been several studies investigating prognostic factors for severe COVID-19, there have been no such studies in Korea. Methods We performed a retrospective observational study of 110 patients with confirmed COVID-19 hospitalized at a tertiary hospital in Daegu, Korea. Demographic, clinical, laboratory, and outcome data were collected and analyzed. Severe disease was defined as a composite outcome of acute respiratory distress syndrome, intensive care unit care, or death. Results Diabetes mellitus (odds ratio [OR], 19.15; 95% confidence interval [CI], 1.90–193.42; P = 0.012), body temperature ≥ 37.8°C (OR, 10.91; 95% CI, 1.35–88.36; P = 0.025), peripheral oxygen saturation < 92% (OR, 33.31; 95% CI, 2.45–452.22; P = 0.008), and creatine kinase-MB (CK-MB) > 6.3 (OR, 56.84; 95% CI, 2.64–1,223.78, P = 0.010) at admission were associated with higher risk of severe COVID-19. The likelihood of development of severe COVID-19 increased with an increasing number of prognostic factors. Conclusion In conclusion, we found that diabetes mellitus, body temperature ≥ 37.8°C, peripheral oxygen saturation < 92%, and CK-MB > 6.3 are independent predictors of severe disease in hospitalized COVID-19 patients. Appropriate assessment of prognostic factors and close monitoring to provide the necessary interventions at the appropriate time in high-risk patients may reduce the case fatality rate of COVID-19.
[Masquelet technique combined with flap transplantation for infectious bone and soft tissue defects of lower leg].

Objective To investigate the effectiveness of Masquelet technique combined with flap transplantation in treatment of infectious bone and soft tissue defects of the lower leg. Methods Between January 2013 and January 2017, 35 cases of infectious bone and soft tissue defects of lower leg were treated with Masquelet technique combined with flap transplantation. There were 21 males and 14 females, with an average of 31.5 years (mean, 25-55 years). All patients were tibial fractures caused by trauma and the infections occurred after debridement or internal fixation. The time from injury to admission was 1 to 6 months, with an average of 3.2 months. Defect located at the proximal leg in 11 cases, the middle leg in 11 cases, and the distal leg in 13 cases. The length of tibia defect after debridement ranged from 5.6 to 11.2 cm, with an average of 7.1 cm. The size of soft tissue defect ranged from 14.2 cm×6.9 cm to 17.3 cm×8.7 cm. Bacterial culture of purulent secretion of wound was positive in 18 cases. After debridement, the bone cement was used to fill the bone defect and the flap transplantation was used to repair the wound. The bone cement was taken out at 8 to 12 weeks after the one-stage operation, and the bone defect was repaired with autogenous iliac bone or combined with artificial bone. Results Three cases had necrosis at the distal edge of the flap after one-stage operation, and survived after dressing change. The other flaps survived successfully, and the wounds healed by first intention. All incisions healed by first intention after two-stage operation. All patients were followed up 24-32 months, with an average of 27 months. The color of the flap was similar to that of the surrounding normal tissue, and its texture was good. X-ray reexamination showed that all bone defects healed after 6-8 months, with an average of 6.7 months. At 9 months after two-stage operation, according to the revised Edwards tibial fracture evaluation standard, 19 cases were excellent, 14 cases were good, and 2 cases were poor, the excellent and good rate was 94.3%. The American Orthopedic Ankle Association (AOFAS) score was 60-98, with an average of 81.3. And 21 cases were excellent, 11 were good, and 3 were fair, with an excellent and good rate of 91.4%. Conclusion Masquelet technique combined with flap transplantation is an effective treatment for infectious bone and soft tissue defects of lower leg.
Early Pregnancy Blood Pressure Elevations and Risk for Maternal and Neonatal Morbidity.

OBJECTIVE To investigate whether women with early pregnancy elevated blood pressure (BP) or stage 1 hypertension exhibit increased risk of preeclampsia and maternal or neonatal morbidity. METHODS We conducted a clinical cohort study of 18,162 women who delivered a singleton neonate from 2015 to 2018 and attended at least two prenatal appointments before 20 weeks of gestation. Data were collected within the Magee Obstetric Maternal and Infant database, an aggregate of prenatal and delivery health records. Early pregnancy BP was defined as average BP before 20 weeks of gestation, and women were classified with normal, elevated BP, stage 1 or 2 hypertension according to current guidelines. The primary outcome was preeclampsia. Secondary outcomes were severe maternal morbidity, placental abruption, gestational diabetes, and composite neonatal morbidity. RESULTS Overall, 75.2% of the women were categorized with normal BP, 13.9% with elevated BP, 5.4% with stage 1 hypertension, and 5.5% with stage 2 hypertension. Risk of preeclampsia increased in a stepwise fashion with increasing BP category, adjusted for covariates (normal BP, 4.7%, referent; elevated BP, 7.3%, adjusted odds ratio [aOR] 1.29, 95% CI 1.07-1.56; stage 1, 12.3%, aOR 2.35, 95% CI 1.86-2.96), and stage 2, 30.2%, aOR 6.49, 95% CI 5.34-7.89). Results were similar among black and white women. Gestational diabetes was more prevalent among women with stage 1 (11.4%; aOR 1.50, 95% CI 1.18-1.91] and stage 2 hypertension (14.2%; aOR 1.65, 95% CI 1.30-2.10). Severe maternal morbidity and neonatal morbidity were increased only among women with stage 2 hypertension (aOR 2.99, 95% CI 2.26-3.99, and aOR 2.67, 95% CI 2.28-3.12, respectively). CONCLUSION Women with elevated BP, and stage 1 and 2 hypertension in early pregnancy are at increased risk for preeclampsia. These findings emphasize the importance of applying the 2017 BP guidelines to reproductive-aged women. Strategies to incorporate these guidelines into obstetric care may also be warranted.
Should the rectal defect be sutured following TEMS/TAMIS carried out for neoplastic rectal lesions? A Meta-Analysis.

INTRODUCTION Management of the rectal defect following transanal endoscopic microsurgery (TEMS) or minimally invasive surgery (TAMIS) carried out for excision of neoplasm in the lower rectum is controversial. We aimed to extract evidence by carrying out a meta-analysis to compare the peri- and postoperative outcomes following rectal neoplasm excision carried out by TEMS and/or TAMIS, whereby the defect is either sutured or left open. METHODS A literature search of Ovid MEDLINE and EMBASE was performed. Full-text comparative studies published until November 2019, in English and of adult patients, whereby TEMS or TAMIS was undertaken for rectal neoplasms were included. The main outcome measures were postoperative bleeding, infection, operative time and hospital stay. FINDINGS Three studies (one randomised controlled trial and two comparative case series) yielded 555 cases (283 in the sutured group and 272 in the open group). The incidence of postoperative bleeding was higher and statistically significant (p = 0.006) where the rectal defect was left open following excision of the neoplasm (19/272, 6.99% vs 6/283, 2.12%). There was no statistical difference between the sutured and open groups regarding infection (p = 0.27; (10/283, 3.53% vs 5/272, 1.84%, respectively), operative time (p = 0.15) or length of stay (p = 0.67). CONCLUSION Suturing the rectal defect following excision of rectal neoplasm by TEMS/TAMIS reduces the incidence of postoperative bleeding in comparison to leaving the defect open. However, suturing makes the procedure slightly longer but there was no statistical difference between both groups when postoperative infection and length of hospital stay were compared.
Theileria orientalis Ikeda genotype infection associated with anaemia, abortion and death in beef cattle in Western Australia.

BACKGROUND Theileria orientalis infection causes a clinical syndrome in cattle characterised by weakness, reluctance to walk, anaemia, jaundice and death in peri-parturient cows and young calves, referred to as bovine anaemia caused by Theileria orientalis group (BATOG). Abortions in pregnant cows are also reported. Pallor, pyrexia and elevated heart and respiratory rates are typical findings on physical examination. CASE REPORT A syndrome of abortions, lethargy, inappetence, jaundice and deaths in beef cattle on two separate properties and a separate cluster of three properties within 15 km west of the town of Denmark in Western Australia was associated with the presence of severe regenerative anaemia and the presence of Theileria orientalis Ikeda genotype in blood samples taken from affected cattle and their cohorts. A diagnosis of bovine anaemia caused by the T. orientalis group was based on consistent clinical, haematological, biochemical and PCR findings. Conventional PCR testing detected only the T. orientalis Ikeda type. On the two properties where it was investigated, quantitative PCR testing for parasite load was suggestive of recent infections. Sequencing of T. orientalis major piroplasm surface protein gene PCR products demonstrated that they were identical to those from similar bovine cases in New South Wales. CONCLUSION The clinical history of affected cattle and the biochemical, haematological and PCR findings were consistent with bovine anaemia caused by the T. orientalis Ikeda genotype. This clinical syndrome had not been recognised in Western Australia before this series of cases.
Microbiome approaches provide the key to biologically control postharvest pathogens and storability of fruits and vegetables.

Microbes play an important role in plants and interact closely with their host starting from sprouting seeds, continuing during growth, and after harvest. The discovery of their importance for plant and postharvest health initiated a biotechnological development of various antagonistic bacteria and fungi for disease control. Nevertheless, their application often showed inconsistent effects. Recently, high-throughput sequencing-based techniques including advanced microscopy reveal fruits and vegetables as holobionts. At harvest, all fruits and vegetables harbor a highly abundant and specific microbiota including beneficial, pathogenic and spoilage microorganisms. Especially, a high microbial diversity and resilient microbial networks were shown to be linked to fruit and vegetable health, while diseased products showed severe dysbioses. Field and postharvest handling of fruits and vegetables was shown to affect the indigenous microbiome and therefore has a substantial impact on the storability of fruits and vegetables. Microbiome tracking can be implemented as a new tool to evaluate and assess all postharvest processes and contribute to fruit and vegetable health. Here we summarize current research advancements in the emerging field of postharvest microbiomes and elaborate its importance. The generated knowledge provides profound insights into postharvest microbiome dynamics and sets a new basis for targeted, microbiome-driven and sustainable control strategies.
Compound optimal allocations for survival clinical trials

The aim of the present paper is to provide optimal allocations for comparative clinical trials with survival outcomes. The suggested targets are derived adopting a compound optimization strategy based on a subjective weighting of the relative importance of inferential demands and ethical concerns. The ensuing compound optimal targets are continuous functions of the treatment effects, so we provide the conditions under which they can be approached by standard response‐adaptive randomization procedures, also guaranteeing the applicability of the classical asymptotic inference. The operating characteristics of the suggested methodology are verified both theoretically and by simulation, including the robustness to model misspecification. With respect to the other available proposals, our strategy always assigns more patients to the best treatment without compromising inference, taking into account estimation efficiency and power as well. We illustrate our procedure by redesigning two real oncological trials.
