AbstractBackgroundTumor necrosis factor (TNF) inhibitors increase the risk of tuberculosis (TB) in patients with rheumatoid arthritis (RA). This study compared the incidence of TB after treatment with TNF inhibitors and tocilizumab in patients with RA, separately in those who were treated for latent tuberculosis infection (LTBI) and those without evidence of LTBI.MethodsThis study included patients with RA who initiated TNF inhibitors and tocilizumab between December 2013 and August 2018. Patient data were collected from the nationwide database of the Health Insurance Review and Assessment service in South Korea. The incidence of TB was compared among different biologic drugs in patients with or without LTBI treatment.ResultsOf 4736 patients, 1168 were treated for LTBI and 48 developed TB (554.9 per 100,000 person-years). When compared based on etanercept, infliximab showed a higher risk of TB (adjusted incidence rate ratio 2.71, 95% confidence interval 1.05–7.01), especially in patients without evidence of LTBI. Other TNF inhibitors and tocilizumab showed a comparable incidence of TB, regardless of treatment for LTBI. There was no significant difference in TB incidence after biologic therapy between patients with and without LTBI treatment (627.9/100,000 vs. 529.5/100,000 person-years). In patients treated for LTBI, no differential risk of TB was observed among biologic drugs.ConclusionsThe incidence of TB was not significantly different among biologic drugs in the current era, except for infliximab in patients who were not treated for LTBI. Treatment of LTBI might alleviate the drug-specific risk of TB in patients with RA.

Abstract
Background
For effective prevention of nosocomial transmissions continuous training and motivation of health care workers (HCW) are essential to maintain and increase compliance with high rates of hand hygiene. The use of Virtual Reality (VR) seems to be a contemporary and interesting approach for hand hygiene training in HCW. Nevertheless, HCW should be asked for their preferences as intrinsic motivation is essential for compliance with hand hygiene and training success should be evaluated.

Methods
A prospective, cross-controlled trial was conducted at two wards in a tertiary care hospital comparing a conventional lecture for hand hygiene to the use of VR. Both interventions were assigned at ward level. Primary outcome was HCW acceptance, which was verified in a third ward, secondary outcomes were hand rub consumption and compliance to indications for hand hygiene as proposed by WHO.

Results
In summary, 81 trainings were conducted, 48 VR trainings and 33 trainings by lecture. VR training was well accepted by HCW with a mean score in all items from 3.9 to 4.3 (out of 5). While most HCW (69%) would prefer VR teaching rather than a lecture for hand hygiene education, only 4% preferred the traditional lecture. 400 observations of hand hygiene indications were made, 50 before intervention and 50 after each intervention at the three wards. Mean proportion of correct and indication-appropriate performances was 81% before intervention, 87% after VR training (p = 0.12), and 95% after lecture (p = 0.04). Hand rub consumption did not change significantly in any group.

Conclusions
Due to the high acceptance of VR technology among healthcare workers, it can be considered an interesting addition to conventional lectures for teaching hand hygiene. However, the hypothesis that VR teaching has a higher impact on hand rub use and hand hygiene compliance than a conventional lecture cannot be confirmed.

Abstract
Background
The objective of this paper is to describe the activities, challenges and mitigation strategies, lessons learned and reflections on the importance of engagement from the first year of the Canadian Consortium on Neurodegeneration in Aging (CCNA) Engagement of People with Lived Experience of Dementia (EPLED) Advisory Group and cross-cutting program. EPLED was created to support persons with dementia and care partners to be actively involved in the CCNA research process.

Main body
The Advisory Group was formed to work with CCNA researchers and programs to develop new ways to further collaborate and advance the methods of patient engagement in research on dementia. A role profile and recruitment poster were developed and, after interviews, 17 people were invited to join the Advisory Group. We planned three online EPLED meetings to take place between July–August of 2020, with one in-person meeting to be held in Canada. Due to COVID-19, we moved all of these meetings online. In the first year, EPLED and the Advisory Group met seven times formally, four times informally, developed a website, engaged with CCNA research projects, participated in CCNA “Central” activities and formulated an evaluation plan. For researchers and people with lived experience of dementia, motivations for patient engagement included challenging stigma, making meaning from their experience (such as building relationships and having their voices heard) and contributing to research. Common challenges to engagement were related to navigating the impact of COVID-19, such as difficulty in getting to know each other and technical issues with video-conference software. We learned that developing trusting relationships, providing education, offering support, being flexible and acknowledging tensions between research, practice and lived experience, were vital to the success of the Advisory Group.

Conclusion
The first year of the EPLED Advisory Group demonstrated the potential contributions of people with lived experience of dementia as partners in research. Building these collaborations with individuals and communities—people living with dementia, care partners, researchers and research institutions—has the potential for positive impact across these groups and, ultimately, improve the lives of people living with dementia and their care partners.

Abstract
Background
Honeybees are one of the most important pollinators in the world, and their products are nowadays included in most anticancer, antiallergic, antimicrobial drugs and are included in cosmetic treatments. In the present study, honeybee venom and Egyptian ethanolic propolis extract (EP) were focused to test their effect on health and some genes for honeybee workers (defensin2, abaecin, hymenoptaecin, vitellogenin, and juvenile hormone esterase).

Results
Honeybee venom and Egyptian propolis extract (EP) were used as supplements in the nutrition with different concentrations in Varroa mites-infected colonies to measure the colonies' activities after treatment. The immune-related genes and antimicrobial peptides (AMPs) were evaluated by using qRT-PCR. Treated colonies with HBV and EP showed up-regulation of immune and immune-related genes' expressions and increased the life span, activities and their density of bee workers. The data illustrated that the highest gene expression fold of juvenile hormone esterase was detected in the treated colonies with Egyptian ethanolic propolis extract (EP), while the highest vitellogenin expression fold in treated colonies was with honeybee venom. The up-regulation of antimicrobial peptides occurred in colonies with both treatments.

Conclusion
The findings suggest that honeybee venom and Egyptian ethanolic propolis extract (EP) could be used as potential supplements, even at the lowest concentration to develop the immunity of worker bees to increase their efficiency and prevent loss of honeybee colonies due to several diseases closely associated with Varroa mites' infections that cause sudden death.

Published: June 2022

Abstract
Background
Indiscriminate disposal of polyethylene materials has become a regular practice among developing nations of Africa, especially in Nigeria. This has resulted in environmental pollution; hence, this study investigates the microbial degradation of polyethylene obtained from a polyethylene dumpsite in South West, Nigeria, under static in vitro condition. Soil samples were analysed for mineral composition and physicochemical characteristics. The fungal isolates were screened for polyethylene degradation using minimal salt medium containing polyethylene as sole source of carbon and nitrogen for their ability to degrade polyethylene. Gravimetric analysis and Fourier-transform infrared spectroscopy (FTIR) were used to monitor the biodegradation of the polyethylene.

Results
Aspergillus flavus, A. nidulans, Penicillium chrysogenum, Mucor mucedo, Eurotium repens, A. fumigatus and Rhizopus stolonifer were enumerated. Mean microbial count ranged from 1.37 × 107 to 8.2 × 108 SFU/g. Individual weight loss was observed in the polyethylene strip cultured with P. chrysogenum (1%), E. repens (1%) and A. nidulans (2%). The changes observed in the FTIR spectra especially the polyethylene sample inoculated with A. nidulans confirm the significant role of fungi in polyethylene degradation. Hence, its usage in the treatment of polyethylene in the environment is a cheap eco-friendly alternative.

Conclusion
Aspergillus nidulans, E. repens and P. notatum play significant roles in the biodegradation of polyethylene which necessitates incorporating in polyethylene products waste management to foster a cleaner environment.

AbstractThe use of vegetable tanning materials in leather processing has drawn attention as an alternative to basic chromium sulphate for its natural abundance and environmental aspects. In this work, an attempt has been made to extract vegetable tannins from Xylocarpus granatum bark using different solvents (e.g., water, methanol, ethanol, and chloroform) and compare with conventional vegetable tanning agents such as mimosa and quebracho. The highest extraction efficiency was observed 31.22% by methanol. The presence of tannin content and polyphenolic compounds, e.g. (-)epicatechin (503 mg/100 g dry extract), catechin hydrate (218 mg/100 g dry extract), catechol (29 mg/100 g dry extract) were ensured by UV–Vis, FT-IR spectroscopy and HPLC. Again, condensed tannins, moisture content, and pH of the methanol extracted tannin were found 47.80%, 5.82%, and 3.97 respectively. The leather tanned by Xylocarpus granatum tannin showed a shrinkage temperature of 86.34 ± 1.52 °C. Other properties such as tensile strength, tear strength, grain cracking load, and distention at grain cracking were comparable to conventional vegetable-tanned leather. The cross-sectional morphology of the tanned leathers was also characterized by scanning electron microscopy (SEM) which revealed a compact structure of the leather fibers. In light of the findings from the study, X. granatum bark tannin could be a well alternative to chromium and a new source of vegetable tannin for the leather industry.

Published: June 2022

Abstract
Background
Intrauterine growth restriction (IUGR) is a common diagnosis in obstetrics and carries an increased risk of perinatal mortality and morbidity. Identification of IUGR is crucial because proper evaluation and management can result in a favourable outcome. Cardiovascular dysfunction and remodelling is a central feature of IUGR. The aim of the study was to use the left modified myocardial performance index (MPI), assess cardiac function in foetuses with intrauterine growth restriction (IUGR) compared to healthy foetuses, and to connect the relationship between changes in MPI and perinatal outcome. A prospective study was conducted with 60 singleton foetuses between 24 and 40 weeks of gestation without foetal chromosomal abnormalities or major malformations, divided into two groups: 30 women with intrauterine growth restriction (30 women) and another 30 women with normal pregnancies (foetal growth pattern appropriate for gestational age and normal heart findings with normal sinus rhythm) who were matched for gestational age and served as the controls. Trans-abdominal ultrasound examination was done with 3.5–7-MHz curvilinear Probe (GE Medical US equipment). The umbilical arteries, middle cerebral artery, and ductus venosus all had blood flow velocity waveforms recorded. The pulsatility index (PI), cerebroplacental ratio (CPR), and Doppler velocimetry (DV) of the umbilical artery were all measured. All foetuses had their myocardial performance index assessed. Normal and abnormal umbilical artery(UA) Doppler, as well as normal and abnormal MCA Doppler, were used to examine the intrauterine growth restriction group. Foetal growth restrictions (FGR) foetuses' Mod-MPI values were compared to gestation-matched controls. The outcomes of the perinatal period were documented.

Results
Intrauterine growth restriction foetuses with defective umbilical arteries Doppler had a substantially higher mean left myocardial performance index (mean 0.58 SD 0.093) than healthy foetuses (mean 0.45SD 0.070) (P 0.001). When compared to the control group, IUGR foetuses with abnormal left myocardial performance index had a significantly worse perinatal outcome and higher morbidity. When compared to intrauterine growth restriction foetuses with normal MPI, intrauterine growth restriction foetuses with defective left MPI had a significantly worse perinatal outcome (whether the UA Doppler was normal or abnormal). Based on the perinatal result, the foetal myocardial performance index was linked to the severity of foetal impairment in intrauterine growth restriction foetuses.

Conclusion
MPI has the potential to be a useful technique for evaluating IUGR pregnancies and predicting neonatal outcome. Within the IUGR foetuses, MPI foetal echocardiographic characteristics can define a high-risk group.

Published: June 2022

Abstract
Background
Neonates with sepsis may have concurrent urinary tract infection (UTI), which may be asymptomatic or have nonspecific symptoms. Failure to diagnose UTI, resulting in a delay of appropriate therapy, has been reported to cause renal scarring, hypertension, and kidney failure among infants. This study aimed to determine the contribution of UTI to neonatal sepsis and to assess different risk factors that could be associated with UTI. This cross-sectional study was conducted at the Neonatal Intensive Care Unit (NICU) of Fayoum University Hospital, Fayoum, Egypt, between March 2018 and January 2019. Neonates of both genders from birth to the 28th day of life with clinical features of either early- or late-onset sepsis (during or after the first 3 days of life, respectively) were enrolled in this study. All neonates were subjected to complete history taking from the parents, full clinical examination, and laboratory investigations including complete blood count, C-reactive protein, blood culture, and urine culture.

Results
The current study included 100 neonates admitted to the NICU with clinical and laboratory features of sepsis. Positive blood culture (proven sepsis) was detected in 60%, and the proportion of positive urine culture (UTI) in the entire study group was 11%. The incidence of UTI was 11.7% in proven sepsis compared to 10% in suspected sepsis, and it was 16.36% in late-onset sepsis (LOS) versus 4.44% in early-onset sepsis (EOS). There was a statistically significant association between poor feeding and feeding intolerance and positive urine culture (UTI). Leukopenia and expert panel criteria score showed high sensitivity (81.80% and 90.90%, respectively) but low specificity for the diagnosis of UTI.

Conclusions
Gram-negative bacteria have been highly suspected in cases of neonatal sepsis. Poor feeding and feeding intolerance have association with positive urine culture. Finally, urine culture for sepsis was recommended especially in the late type.
Clinical effects of TP-based hyperthermic intraperitoneal chemotherapy (HIPEC) on CD133 and HE4 expression in advanced epithelial ovarian cancer
Authors: Su Xianhui , Sun Xuewen , Wang Ying , Kang Yanhui , Dai Yuna 
Published: June 2022

Objectives: To investigate the clinical effects of TP-based hyperthermic intraperitoneal chemotherapy (HIPEC) on the levels of antigen cluster protein 133 (CD133) and human epididymal secretory protein 4 (HE4) in patients with advanced epithelial ovarian cancer (EOC).
Methods: A total of 104 patients with advanced EOC hospitalized in Affiliated Hospital of Hebei Engineering University from April 2015 to December 2018 were assigned to two groups using a random number table. A control group (n =52) treated by the conventional postoperative TP regimen and an observation group (n =52) receiving HIPEC in addition to the conventional postoperative TP regimen. CD133 and HE4 expression in serum, overall response rate (ORR), long-term efficacy, and incidence of drug toxicity were measured for comparative analysis.
Results: The serum levels of CD133 and HE4 expression in the observation group were lower than in the control group (P < 0.005, respectively); the observation group surpassed the control group in ORR, 2-year survival, and progression-free survival (PFS) (P < 0.005, respectively); however, the two groups had no statistically significant difference in the incidence of drug toxicity (P > 0.05).
Conclusions: TP-based HIPEC can effectively inhibit CD133 and HE4 expression in advanced EOC, which thereby improves the clinical efficacy and encourages longer survival.

Authors: Mu Wei-na , Li Jian-heng , Liu Ying , Liang Hui-qing , Liu Xin 
Published: June 2022

Objectives: To compare the diagnostic efficacy of fine needle aspiration (FNA) and core needle biopsy (CNB) for metastatic lymph nodes guided by contrast-enhanced ultrasound (CEUS), and to provide reference for clinical selection of puncture methods.
Methods: A total of 168 patients who were admitted to Baoding No.1 Central Hospital from June 2020 to January 2021 and required puncture of the diseased lymph nodes were included. Seventy six patients were guided by conventional ultrasound, of which 37 received FNA and 39 received CNB. 92 patients were guided by CEUS, of which 41 received FNA and 51 received CNB. The diagnostic accuracy of FNA and CNB guided by conventional ultrasound and CEUS was compared, and the sensitivity, specificity, positive predictive value, and negative predictive value of FNA and CNB in the diagnosis of metastatic lymph nodes guided by CEUS were further compared.
Results: The diagnostic accuracy of FNA and CNB guided by CEUS were higher than that guided by conventional ultrasound, with a statistically significant difference (P<0.05). The sensitivity, specificity, positive predictive value, and negative predictive value of FNA and CNB in the diagnosis of metastatic lymph nodes were 95.0%, 95.2%, 95.0%, 95.2%, 100%, 100%, 100%, 100%, respectively, with statistically significant differences (P>0.05).
Conclusion: CEUS can guide puncture and improve diagnosis accuracy. No statistical difference can be seen in the diagnostic efficacy of CNB and FNA for metastatic lymph nodes, CNB can provide more diagnostic information, while FNA can replace CNB for metastatic lymph nodes adjacent to blood vessels and difficult to operate.
