BackgroundChina recorded a massive COVID-19 pandemic wave after ending its Dynamic Zero-COVID Policy on January 8, 2023. As a result, mental health professionals (MHPs) experienced negative mental health consequences, including an increased level of fear related to COVID-19. This study aimed to explore the prevalence and correlates of COVID-19 fear among MHPs following the end of the Policy, and its association with quality of life (QoL) from a network analysis perspective.MethodsA cross-sectional national study was conducted across China. The correlates of COVID-19 fear were examined using both univariate and multivariate analyses. An analysis of covariance (ANCOVA) was conducted to determine the relationship between fear of COVID-19 and QoL. Central symptoms were identified using network analysis through the “Expected Influence” of the network model while specific symptoms directly correlated with QoL were identified through the “flow function.”ResultsA total of 10,647 Chinese MHPs were included. The overall prevalence of COVID-19 fear (FCV-19S total score ≥ 16) was 60.8% (95% CI = 59.9–61.8%). The binary logistic regression analysis found that MHPs with fear of COVID-19 were more likely to be married (OR = 1.198; p &lt; 0.001) and having COVID-19 infection (OR = 1.235; p = 0.005) and quarantine experience (OR = 1.189; p &lt; 0.001). Having better economic status (good vs. poor: OR = 0.479; p &lt; 0.001; fair vs. poor: OR = 0.646; p &lt; 0.001) and health status (good vs. poor: OR = 0.410; p &lt; 0.001; fair vs. poor: OR = 0.617; p &lt; 0.001) were significantly associated with a lower risk of COVID-19 fear. The ANCOVA showed that MHPs with fear of COVID-19 had lower QoL [F = 228.0, p &lt; 0.001]. “Palpitation when thinking about COVID-19” was the most central symptom in the COVID-19 fear network model, while “Uncomfortable thinking about COVID-19” had the strongest negative association with QoL (average edge weight = −0.048).ConclusionThis study found a high prevalence of COVID-19 fear among Chinese MHPs following the end of China’s Dynamic Zero-COVID Policy. Developing effective prevention and intervention measures that target the central symptoms as well as symptoms correlated with QoL in our network structure would be important to address COVID-19 fear and improve QoL.
The use of Zuckerkandl's tubercle as an anatomical landmark in identifying recurrent laryngeal nerve and superior parathyroid gland during total thyroidectomy: a prospective single-surgeon study
Authors: Gurluler Ercument 
Published: October 2023

ObjectiveTo determine the incidence and characteristics of Zuckerkandl's tubercle (ZT), and its relationship with recurrent laryngeal nerve (RLN) and the superior parathyroid gland (SPG) in the setting of total thyroidectomy.MethodsA total of 421 patients (mean (min-max) age: 45.6 (18–78) years, 76.2% were females) who had total thyroidectomy were included in this prospective single-surgeon thyroidectomy series study. Patient demographics and thyroidectomy indications (benign and malignant) were recorded in each patient. The presence, grade and laterality of ZT, and its relationship with RLN and SPG were recorded during surgery.ResultsMost of the thyroidectomy indications (69.1%) were related to a malignant disease. The ZT was unrecognizable in 41(9.7%) of 421 patients. In 380 patients with identifiable ZT, the grade 2 (46.3%) ZT was the most common finding. Majority of ZTs (92.9%) were unilaterally located (right-sided: 64.9%; left-sided: 35.1%). In majority of the cases (83.2%), the RLN was found to lie medial to ZT. Overall, SPG was identified in close proximity to ZT in 66.6% of patients (Class 2 [0.5–1 cm from ZT] in 46.6% and Class 3 [&lt;0.5 cm from ZT] in 20.0%). SPG was more likely to be identified in close proximity to ZT when the grade of ZT was higher, which was found to be located 0.5–1 cm from the ZT in 56.9% and 42.7% of grade 2 and grade 3 ZTs, respectively, and &lt;0.5 cm from the ZT in 46.1% of grade 3 ZTs.ConclusionIn conclusion, this prospective single-surgeon thyroidectomy series study indicates the likelihood of localizing the RLN medial to ZT, and the SPG in close proximity to ZT during total thyroidectomy operations. Hence, the ZT can be used as a reliable and constant landmark to localize both the RLN and the SPG during thyroid surgery, which enables minimizing the risk of iatrogenic injury to RLN, while ensuring a parathyroid-sparing thyroidectomy. The thyroid surgeon should have complete knowledge of thyroid gland anatomy and embryogenesis and should follow a careful and meticulous approach particularly for dissections around larger ZTs, given the increased likelihood of SPG and RLN to be in close proximity.

The exacerbation of climatic changes helped to increase the risk of plant diseases in the world. The novelty of this study lies in the manufacture of therapeutic nutrients using nanotechnology with strong effectiveness against plant disease. Based on this concept, we mycosynthesized bimetallic ZnO-CuO nanoparticles (NPs), alternatives to reduce the spread of Vicia faba Fusarium wilt disease, which is one of the world’s most imperative cultivated crops. The article’s uniqueness comes in the utilization of ZnO-CuO nanoparticles to carry out two crucial tasks: therapeutic nutrients and managing Fusarium disease. To evaluate the resistance of infected plants, disease index (DI), photosynthetic pigments, osmolytes, oxidative stress and yield parameters were assessed. NPs of ZnO, CuO, and ZnO-CuO were mycosynthesized using a biomass filtrate of Aspergillus fumigatus OQ519856. DI reached 87.5%, due to Fusarium infection, and, as a result, a severe decrease in growth characters, photosynthetic pigments, total soluble carbohydrates, and proteins as well as yield parameters was observed. Infected plants produced more of the studied metabolites and antioxidants. On the other hand, the treatment with CuO-ZnO NPs led to a great decline in the DI by 22.5% and increased the protection by 74.28%. A clear improvement in growth characters, photosynthetic pigments and a high content of carbohydrates and proteins was also observed in both healthy and infected plants as a result of CuO-ZnO NPs treatment. Remarkably, CuO-ZnO NPs significantly increased the yield parameters, i.e., pods/plant and pod weight, by 146.1% and 228.8%, respectively. It could be suggested that foliar application of NPs of ZnO, CuO, and ZnO-CuO could be commercially used as antifusarial agents and strong elicitors of induced systemic resistance.

Pengelasan Stainless Steel 304 (SS 304) umumnya menggunakan metode pengelasan GTAW, karena SS 304 termasuk baja paduan. Selain pemilihan metode las yang tepat, penentuan jenis kampuh juga menjadi salah satu pertimbangan pengelasan untuk kualitas hasil las, pemilihan sambungan yang tepat akan membuat konstruksi semakin baik dan aman. Penelitian ini bertujuan untuk mengetahui kualitas hasil sambungan las dengan tipe kampuh yang berbeda. Penelitian ini menggunakan material SS 304, filler pengisi ER308 dengan menggunakan mesin las GTAW. Pengujian hasil lasan dengan metode non destructive test (NDT) menggunakan uji visual dan uji dye penetrant. Sedangkan pengujian mekanik meliputi uji kekerasan Vickers dan uji tarik. Hasil dari uji visual dan dye penetrant, pada daerah lasan tidak terdapat cacat, baik itu pada bagian permukaan luar maupun dalam. Pada pengujian mekanik kekuatan rata-rata uji kekerasan Vickers kampuh tipe V memiliki nilai kekuatan yang lebih baik sebesar 200,63 VHN sedangkan untuk kampuh tipe X nilainya sebesar 195,31 VHN. Pada pengujian mekanik menggunakan pengujian tarik didapat nilai rata-rata kekuatan tarik, perpanjangan (elongation) dan modulus elastisitas kampuh tipe X lebih tinggi daripada kampuh tipe V, dengan nilai rata-rata kampuh tipe X Fmax=4578 kgf, ε=12,6% dan E=312 kgf sedangkan kampuh tipe V nilainya Fmax=3581 kgf, ε=9,3% dan E=308,76 kgf. Hasil pengujian menunjukkan bahwa hasil uji NDT, yaitu uji visual dan dye penetrant pada kedua tipe kampuh memiliki hasil yang sama baik, sedangkan untuk pengujian DT, kedua tipe kampuh memiliki perbedaan yang tidak terlalu signifikan, jadi melihat hasil kualitasnya pengelasan kedua kampuh dapat di aplikasikan pada kebutuhan konstruksi yang nanti akan dipakai.

Objective: We aim to identify appendiceal neuroendocrine tumors (NETs) seen after acute appendicitis and investigate their incidence in patients with laparoscopic or open appendectomy surgery. Here we have shaped the characteristic features of the tumor according to the 2010 classification rating of The World Health Organization (WHO) (surgical margin, invasion, grading, TNM stages) and also explored the disease-free survival in these patients.
Material and Methods: This is the medical record of the patient with 7266 appendectomy retrospectively evaluated, and with these examples in histopathological analysis, a total of 43 patients were diagnosed with appendicitis NETs and included in the study. Age, gender, prediction of the surgical team during the operation, location of the tumor, WHO grade, depth of invasion, positive surgical margin, tumor size, TNM stage, and postoperative survival of these patients were analyzed retrospectively.
Results: In this study, the incidence of appendiceal (NETs) was found to be 0.59% among 7,266 patients. Out of the 42 patients with appendiceal NETs, 27 were female and 16 were male. The mean age of the patients was 33.65 years (range: 11–78). The diagnosis was aided by clinical examination, ultrasound, and abdominal computerized tomography (CT) imaging. Most patients were initially diagnosed with appendicitis, and surgical interventions, including laparoscopic and conventional appendectomy, were performed. The pathological analysis confirmed appendicitis with NETs, classified according to the WHO 2010 recommendation. The majority of patients had well-differentiated NETs (G1 or G2). Surgical resection achieved negative radial margins, and no pathological signs were detected during follow-up colonoscopies. At a median follow-up of 70.2 months, all patients remained disease-free and alive.
Conclusion: Appendiceal neuroendocrine tumors are rare but distinct entities that require a multidisciplinary approach for diagnosis and management. Surgical resection is the primary treatment, with systemic therapies reserved for advanced cases. The prognosis is generally favorable, with better outcomes seen in well-differentiated tumors. Long-term follow-up is crucial. Further research is needed to improve understanding and optimize treatment strategies for these tumors.

Abstract: This study aims to develop, translate and validate a newly developed Malaysian survey that assesses the propensity to volunteer through the employment of a 3-phase cross-sectional study. Phase 1 consisted of two components, content and face validity evaluation. A four-person expert panel was involved in the assessment of the content validity of the new survey. Meanwhile, the responses garnered from ten respondents representing the target population were used to evaluate face validity. Next, Phase 2 consisted of forward and backward translations, with an expert committee established to review the translated version. Finally, Phase 3 consisted of the employment of Cronbach’s Alpha utilised for the reliability analysis to test the internal consistency of the items. Subsequently, the SAS software was employed for data analysis. The findings indicated that out of 20 items, eight items showed the content validity indeks (I-CVI) value to be less than 0.78, and the expert panel omitted them from the survey in Phase 1. Phase 2 also included Cohen's Kappa Coefficient for all the items between the English and Malay version, which indicated a value of more than 0.62 and possessed good agreement. Moreover, in Phase 3, the Cronbach’s Alpha for the English and Malay version indicated excellent internal consistency (for both the language versions, the values were similar; 0.93). Thus, from the findings, it is evident that the English (MySPV-E) and Malay (MySPV-M ) versions of the survey are reliable, valid, and proved to be appropriate tools to assess an individual’s propensity to volunteer in a Malaysian population.

Abstract: COVID-19 is one of the most threatening pandemics in recent times. People worldwide became terrified because of the risk of contagion, the high rate of fatality, particularly among the elderly, and the effects on people's social, economic, political, and cultural lives. Despite the risk associated with the Pandemic, the Nigerian populaces have different attitudes regarding the usefulness of information and believability, especially on social media. This study examines gender differences in Covid-19 attitudes towards related information on social media among undergraduate students of Ahmadu Bello University Zaria. The study employed a qualitative approach, and interviews were used to collect data. Purposive sampling techniques were used in selecting respondents. The participants consist of six female students and six male students. Overall, twelve students were selected to respond to the interview questions. Purposive sampling techniques were used in selecting respondents. The data were analyzed using thematic analysis. The findings showed an insignificant gender difference in Covid-19 attitudes and beliefs among students. The result further indicated that females do not value Covid-19 related information posted on social media by individuals.
