Background
The nursing workforce shortage has long been a global concern, and with the aging of nurses, this problem has become more prominent. Nursing is recognized as a high-stress occupation, and nurses experience high levels of job burnout, which reduces their professional identity. Older nurses are an indispensable talent force for nursing teams and are extremely important for the stability of nursing teams and improvement in nursing quality. Exploring the mental health and influencing factors of older nurses is very beneficial for the stability and development of nurse teams and patients’ clinical outcomes.

Purpose
This study aimed to investigate the level of job burnout and its influencing factors among older nurses in Guizhou Province, China and confirm the correlations among job burnout, professional identity and stress level.

Methods
From July to August 2019, 520 registered nurses aged over 40 years in Guizhou Province, China were surveyed through the Questionnaire Star platform. The questionnaire contained the following four parts: a general information questionnaire, the Maslach Burnout Inventory (MBI), a professional identity scale, and a job stressors scale.

Results
The results showed that the job burnout score of the 520 older nurses was 55.44 ± 18.62, which was moderate. The level of job burnout was positively correlated with the level of nurse stress and negatively correlated with the level of professional identity, which was influenced by various personal and social factors.

Conclusions
This study not only revealed that job burnout was still at a moderate level, but also revealed its current status and influencing factors among older nurses in China.

Published: October 2021

The cytotoxicity potentials of methamphetamine (METH) is presumably associated with oxidative stress induced apoptosis, this study therefore, investigated the toxic potentials of METH in neuroblastoma cells and further determined it effects on the mitochondrial activity.
Human neuroblastoma SK-N-BE (2) cells cultured in DMEM/F12 were used in this study. The cells were treated acutely with methamphetamine (1, 5, 10, 20, and 50 µg/mL) over 24, and were allowed to recover from METH treatment over 48, 72, and 96 h. Cell viability study was done with Trypanblue exclusion assay. The cell proliferative characteristics of the neuroblastoma cell line were investigated by constructinga cell proliferation curve. Mitochondrial activity was assessed using the XTT Assay. Statistical analysis were done with Graph Pad prism and significant difference were considered at p<0.001, 0.01 and 0.05.
The result showed normal growth in the untreated neuroblastoma cell over the 96 h of monitoring. Following treatment with METH, significant decrease in cell growth was observed when treated acutely with 5 and 10 µg/mL METH and allowed till 72 and 96 h recovery period. The SK-N-BE (2) treated with increasing concentration of METH showed no significant difference in cell viability over the recovery period from METH exposure. Toxicity of SK-N-BE (2) cells was only observed when treated with 10 µg/mL of METH. Significant decrease in mitochondria activity was observed when the cells were treated with 5, 10, 20, and 50 µg/mL METH and allowed till 72 h recovery.
The result showed that METH is cytotoxic to the SK-N-BE (2) cells and the mechanism of toxicity might be associated with inhibition of mitochondrial activity.

Aims: Livestock is the largest subsector of the Sudanese domestic economy and is a growing contributor to exports. Rift Valley fever (RVF) is an economically important arthropod-borne virus disease in Africa, primarily affecting sheep, goats, and cattle. RVF causes paramount loss in sheep industry in Sudan. The objective of this study was to detect RVF in sheep.
Methodology: Five hundred and fifty-six sheep blood Serum from inoculated animals was collected from six study areas in the Gezira (Sudan)was evaluated for the presence of neutralizing antibodies using the diagnostic kit (ID. Vet.) for detecting antibodies directly against the RVFV nucleoprotein (NP) in serum and Reverse transcription (RT)-Polymerase Chain Reaction (PCR) protocol was used as standard test to diagnose and confirm RVFV among studied animals.
Results: The ELISA test indicated that the highest Seroprevalence was found at Shikaira (38%), while samples from Albasabeir, Wad alnaem and Umalqura tested positive for antibodies against RVFV by 15%, 10% and 9% respectively. The lowest Seroprevalence found at Wad anor and Shabona (5% and 2%). The overall seroprevalence was 14.2% in the study sites, there is no significant difference among the six study sites with respect to seroprevalence. The Rt-PCR provided more sensitive and specific detection of RVFV in serum samples (sensitivity= 95% specificity = 80%).
Conclusion: The results from this study showed the presence of anti-RVFV antibodies in all study sites, suggesting that RVFV is actively circulating among sheep in Gezira state. The high seroprevalence of RVFV infection in Gezira state indicates its endemicity. Test validation using ROC analysis was able to distinguished between ELISA (actual class) and the PCR (predicted class) and the AUC = 0.79 which indicate that the PCR is gold standard test. Thus Rt-PCR used in the present study is reliable to detect precisely the M segment of RVFV and it is valuable for Wide area survey, among both sheep and Aedes spp. Targeting the prevailing genotypes of RVF-M segment, especially at high-risk areas and as a confirmatory test that should be considered by reference laboratories in the region.

Published: October 2021

Background: Chronic endometritis (CE) is a chronic inflammatory condition characterized by the presence of plasma cells in endometrial stroma. CE is a subtle disease, often overlooked by clinicians due to poor symptomatology, such as uterine bleeding, pelvic discomfort, dyspareunia, and leucorrhoea.
Methods: This cohort prospective study was conducted at Tanta University hospitals aiming to evaluate the efficacy of hysteroscopy in the diagnosis of chronic endometritis in infertile females. We included a total of 80 infertile females who were subjected to complete history taking, general examination, and complete gynaecological investigations. Routine laboratory parameters were also performed. In addition, hysteroscopic examination was performed for all cases with endometrial biopsy.
Results: Our results showed that the mean age of the included cases was 26.6 years (range, 20 – 36), the mean BMI of the included cases was 30.51 kg/m2, Hysteroscopic examination revealed endometrial hyperemia (85.4%), stromal edema (52.1%), and endometrial polyps (43.75%), Hysteroscopic diagnosis of chronic endometritis was established in 48 cases (60%). Nevertheless, pathological examination confirmed the diagnosis only in 33 cases (41.25%), Hysteroscopy had sensitivity and specificity of 81.89 and 55.3% respectively, with an accuracy of 66.25% in detecting chronic endometritis, Agreement between hysteroscopic and pathological had kappa factor of 0.325 (p = 0.004), On immunohistochemical analysis of chronic endometritis specimens, CD138 was positive in 31out of 33 cases (93.93%).
Conclusions: Office hysteroscopy is a reliable examination for investigating chronic endometritis. It could be useful for screening asymptomatic infertile patients. The chronic endometritis is a hidden condition that is difficult to detect with non-invasive examination, we suggest that hysteroscopy should be always performed in the diagnostic work-up of women with unexplained infertility, especially before starting assisted reproduction procedures. Also, endoscopic samples should be obtained during hysteroscopy to increase the diagnostic accuracy.

Aggressive script rehearsal in adult offenders: Relationships with emotion regulation difficulties and aggressive behavior
Authors: Hosie Julia , Dunne Ashley Lauren , Meyer Denny , Daffern Michael 
Published: October 2021

AbstractThis study explored relationships between self‐reported emotion regulation difficulties, frequency of aggressive script rehearsal and aggressive behavior in 129 adult male inmates. Significant moderate positive correlations were found between the frequency of aggressive script rehearsal and (1) emotion regulation difficulties overall, as well as the following dimensions, (2) difficulties controlling impulses when experiencing negative emotions, and (3) confidence in the effectiveness of emotion regulation strategies. Significant weak positive correlations were found between the frequency of aggressive script rehearsal and two emotion regulation difficulty dimensions, (1) a lack of understanding of emotional responses, and (2) difficulties in dealing with goal directed behavior when experiencing uncomfortable emotions. No significant correlations were found between aggressive behavior and emotion regulation difficulties, except for a weak positive correlation between aggressive behavior and difficulties controlling impulses when experiencing negative emotions. Multivariate analyses were used to assess whether the frequency of aggressive script rehearsal moderated the effect of emotion regulation difficulties on aggressive behaviour. Significant improvement in the prediction of aggression resulted from consideration of the interaction between (1) aggressive script rehearsal and difficulties in emotional clarity, and (2) aggressive script rehearsal and awareness of emotional experience, even after accounting for the influence of age and attitudes toward violence. In conclusion, the results suggest that the rehearsal of aggressive scripts may function to regulate emotion, particularly amongst people who are inattentive to their emotions or who have difficulty understanding their emotional experiences.

AbstractElectrochemical H2O2 production through the 2‐electron oxygen reduction reaction (ORR) is a promising alternative to the energy‐intensive anthraquinone process. Herein, by simultaneously regulating the coordination number of the atomically dispersed cobalt sites and the nearby oxygen functional groups via a one‐step microwave thermal shock, a highly selective and active CoNC electrocatalyst for H2O2 electrosynthesis that exhibits a high H2O2 selectivity (91.3%), outstanding mass activity (44.4 A g−1 at 0.65 V), and large kinetic current density (11.3 mA cm−2 at 0.65 V) in 0.1 m KOH is obtained. In strong contrast to the typical CoN4 moieties for the 4‐electron ORR, the present CoNC catalyst possesses a low‐coordinated CoN2 configuration and abundant epoxide groups, which work in synergy for promoting the 2‐electron ORR, as demonstrated by a series of control experiments and theoretical simulations. This study may provide an effective avenue to modulating the composition and structure of electrocatalysts at the atomic scale, leading to the development of new electrocatalysts with unprecedented reactivity.

Published: October 2021

AbstractElectrochemical proton storage provides high energy, fast kinetics, safety, and environmental friendliness for grid‐scale energy storage. However, the development of pseudocapacitive proton supercapacitors with fast chargeability and high stability is still challenging because of the unclear electrochemical reaction mechanism and unsuitable construction strategy. Here it is shown that a multi‐metallic Prussian blue analog—Cu0.82Co0.18HCF, which possesses enhanced electronic structure and ion transport path—can intercalate/de‐intercalate large amounts of proton at high rates. Ion‐induced transformation of magnetism, fast solid‐state proton transport, and reversible insertion/de‐insertion of protons lead to extremely excellent rate capacities and cycling stability for proton storage. An asymmetric pseudocapacitive proton supercapacitor (Cu0.82Co0.18HCF//WO3·nH2O) is fabricated with a voltage window of 1.7 V, delivering a maximum energy density of 35 Wh kg−1 and an energy density of 22 Wh kg−1 at a high power density of 26 kW kg−1. Combining systematical material design and mechanism study, this work not only broadens the preparation of electrode materials but also brings light to the construction of high‐performance devices for efficient proton storage.

Published: October 2021

AbstractThe lack of advanced electrode materials is one of the main factors hindering the development of flexible rechargeable aqueous batteries (RABs) for high specific energy density and structural stability. It is also challenging to achieve high‐capacity performance for both the positive and negative electrodes simultaneously. Here, it is demonstrated that, by smartly designing the composite structures of positive and negative electrodes via one‐step electrodeposition strategy, the energy storage performance of the RAB is largely enhanced. For positive electrode material synthesis, Co‐Cu double hydroxides (Co‐Cu‐DH) nanosheets are skillfully rooted into electroreduced graphene oxide (eRG) via hydrogen bonding, in which graphene oxide reduction, Co‐Cu‐DH nucleation/growth, and formation of hydrogen bonding between Co‐Cu‐DH and eRG simultaneously occur. Moreover, when a RAB based on Co‐Cu‐DH@eRG//FeOOH@eRG using the same composite design strategy is established, a wide operating voltage window of ≈1.8 V, a high specific energy density of ≈142.8 Wh kg−1 at ≈890 W kg−1, and long‐term cyclic stability (88.5% of capacity retention after 12 000 cycles) are obtained. This study presents a general compositing strategy for the development of advanced electrode materials, and it is expected to stimulate future material synthesis/design in RABs toward the goal of high energy density storage.
