Published: July 2023

Abstract
Background
Healthcare professionals working in long-term care facilities reported heavy job demands and a lack of job resources during the 2019 coronavirus disease (COVID-19) pandemic. However, how job demands and resources in these facilities changed during the pandemic, and how possible changes affected professionals’ work-related well-being, remains unclear. Thus, we explored changes in job demands and resources in the face of surging COVID-19 infection rates, and investigated associations of these changes with changes in burnout and work engagement, among healthcare professionals working in long-term care facilities in the Netherlands.

Methods
This longitudinal study was conducted with healthcare professionals working in five long-term care facilities in the Netherlands. Data were collected in early and late 2021, when infection rates in long-term care facilities were low and high (mean, 29.1 and 275.4 infections/day), respectively. In total, 173 healthcare professionals completed the validated Job Demands and Resources Questionnaire, Copenhagen Burnout Inventory, and Utrecht Work Engagement Scale at both timepoints. We performed paired-samples t tests to examine changes in job demands and resources, and fixed-effects linear regression analyses to examine associations of within-person changes in job demands and resources with those in burnout and work engagement.

Results
Healthcare professionals perceived increased workloads, associated with increased burnout and decreased work engagement during the study period. Within-person increases in perceived collegial support were associated positively with work engagement and negatively with burnout symptoms.

Conclusions
Healthcare professionals in long-term care facilities perceived increased workloads in the wake of surging infection rates during the COVID-19 pandemic, resulting in increased burnout and decreased work engagement. These changes in burnout and work engagement were also perceived in response to declining collegial support. Efforts to protect the work-related well-being of healthcare professionals working in long-term care facilities in the pandemic context that focus on workload reduction and the promotion of collegial support may be most beneficial.

Published: July 2023

Abstract
Background
Stereotactic body radiotherapy (SBRT) is a novel radio-therapeutic technique that has recently emerged as standard-of-care treatment for medically inoperable, early-stage non-small cell lung cancer (NSCLC). In this study, we compared the cost-effectiveness of SBRT with that of conventional fractionated radiotherapy (CFRT) in patients with medically inoperable, early-stage NSCLC from the perspective of the Chinese health system.

Methods
A Markov model was developed to describe health states of patients after treatment with SBRT and CFRT. The recurrence risks, treatment toxicities, and utilities inputs were obtained from the literature. The costs were based on listed prices and real-world evidence. A simulation was conducted to determine the post-treatment lifetime years. For each treatment, the total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) per QALY were calculated. Deterministic and probabilistic sensitivity analyses were performed to assess the uncertainty of the model parameters.

Results
In the base case analysis, SBRT was associated with a mean cost of USD16,933 and 2.05 QALYs, whereas CFRT was associated with a mean cost of USD17,726 and 1.61 QALYs. SBRT is a more cost-effective strategy compared with CFRT for medically inoperable, early-stage NSCLC, with USD 1802 is saved for every incremental QALY. This result was validated by DSA and PSA, in which SBRT remained the most cost-effective option.

Conclusions
The findings suggested that, compared to CFRT, SBRT may be considered a more cost-effective strategy for medically inoperable, early-stage NSCLC.

AbstractOutcomes for patients with melanoma have improved over the past decade with the clinical development and approval of immunotherapies targeting immune checkpoint receptors such as programmed death-1 (PD-1), programmed death ligand 1 (PD-L1) or cytotoxic T lymphocyte antigen-4 (CTLA-4). Combinations of these checkpoint therapies with other agents are now being explored to improve outcomes and enhance benefit-risk profiles of treatment. Alternative inhibitory receptors have been identified that may be targeted for anti-tumor immune therapy, such as lymphocyte-activation gene-3 (LAG-3), as have several potential target oncogenes for molecularly targeted therapy, such as tyrosine kinase inhibitors. Unfortunately, many patients still progress and acquire resistance to immunotherapy and molecularly targeted therapies. To bypass resistance, combination treatment with immunotherapies and single or multiple TKIs have been shown to improve prognosis compared to monotherapy. The number of new combinations treatment under development for melanoma provides options for the number of patients to achieve a therapeutic benefit. Many diagnostic and prognostic assays have begun to show clinical applicability providing additional tools to optimize and individualize treatments. However, the question on the optimal algorithm of first- and later-line therapies and the search for biomarkers to guide these decisions are still under investigation. This year, the Melanoma Bridge Congress (Dec 1st–3rd, 2022, Naples, Italy) addressed the latest advances in melanoma research, focusing on themes of paramount importance for melanoma prevention, diagnosis and treatment. This included sessions dedicated to systems biology on immunotherapy, immunogenicity and gene expression profiling, biomarkers, and combination treatment strategies.
MiR-320a upregulation improves IL-1β-induced osteoarthritis via targeting the DAZAP1 and MAPK pathways
Authors: Mao Jing , Zhang Lei 
Published: July 2023

Abstract
Purpose
Osteoarthritis (OA), a constant illness described by articular cartilage degeneration, usually manifested by joint pain and helpless development. Numerous literatures suggest that microRNAs play an important regulatory role in OA, yet the role of miR-320a in OA remains largely obscure.

Materials and methods
To evaluate the expression of miR-320a mRNA, quantitative real-time polymerase chain reaction was used. Cell counting kit-8 assay, Edu staining, Annexin V-FITC/PI apoptosis detection assay, Caspases 3 staining, and trypan staining were conducted to monitor cell proliferation and apoptosis. Western blot was applied to examine DAZAP1 and ERK/JNK/MAPK associated protein expression. Luciferase reporter gene experiments were performed to confirm the relationships between miR-320a and DAZAP1. ELISA assay was adopted to analyze the secretion of inflammation cytokines IL-6, IL-8, and TNF-α.

Results
In an in vitro osteoarthritis model caused by IL-1β, miR-320a expression was markedly reduced. Overexpression of miR-320a restored IL-1β-inhibited chondrocyte proliferation, induced apoptosis and inflammatory response. Mechanistically, miR-320a affected HC-A cell proliferation, apoptosis and inflammatory response by regulating DAZAPI. Meanwhile, the ERK/JNK/MAPK pathway is also involved in the regulatory role of miR-320a on OA.

Conclusion
Our results show an important role for miR-320a and provide new therapeutic targets for avoiding and treating osteoarthritis.
High tibial osteotomy improves balance control in patients with knee osteoarthritis and a varus deformity
Authors: Zhang Zheng , Tao Hai , Zhao Yingchun , Xiang Wei , Cao Hui , Tao Fenghua 
Published: July 2023

Abstract
Background
Impaired knee stability is observed in patients with medial compartment knee osteoarthritis (OA) and varus malalignment. Although high tibial osteotomy (HTO) is widely used to treat OA-related knee varus deformity, its long-term influence on balance control in OA patients is poorly reported. This study aimed to evaluate the impact of HTO on balance control and assess its biological and functional significance.

Methods
Thirty-two patients with medial compartment knee OA as well as varus deformity who were scheduled for HTO underwent static posturographic tests one month pre- and three months as well as one year postoperatively, respectively, along with forty matched control subjects. Radiographic and clinical evaluations were synchronously carried out on patients pre- and postoperatively.

Results
Decreased postural sway was observed in patients one year after HTO. When compared to the control subjects, more postural sway was found in patients one month pre- and three months postoperatively. No difference was observed between the patients and control subjects one year postoperatively. The alignment and joint function of the affected knees significantly improved after HTO.

Conclusions
This study revealed that HTO improves balance control in patients with knee OA and varus deformity. Correct alignment and improved joint function enhance the likelihood of normal postural stability. Hence, this intervention allows the knee joint to recover its corrective compensatory role in postural regulation and should be taken into account for managing knee OA patients.

AbstractAntibody–drug conjugates (ADCs) combine the cytotoxicity of small-molecule drugs with antibody targeting. Due to their precise and powerful effect, they have become a new hotspot and an important trend in the research and development of anti-tumor antibody drugs. Every year, exciting new developments and innovations in the treatment of urological tumors are introduced at the American Society of Clinical Oncology-Genitourinary (ASCO-GU) Cancers Symposium. In this article, we summarize some of the most impressive advances in new clinical trials and clinical data on ADCs in the 2023 ASCO-GU Cancers Symposium for the treatment of urothelial carcinoma.
BCMA-targeted CAR-T cell therapies in relapsed and/or refractory multiple myeloma: latest updates from 2023 ASCO Annual Meeting
Authors: Wu James F. , Dhakal Binod 
Published: July 2023

AbstractTreatment of relapsed and/or refractory multiple myeloma (RRMM) utilizing the novel therapeutic target of the B-cell maturation antigen (BCMA) has demonstrated incredible results, leading to regulatory approval of BCMA-targeted chimeric antigen receptor (CAR)-T cell therapies in RRMM. With now two approved BCMA-targeted CAR-T cell therapies, investigators globally are working to build off and improve upon BCMA-targeted therapies. We discuss long-term data from the pivotal study that led to CAR-T approval, a phase 3 trial supporting their use in earlier lines, and novel manufacturing platforms to decrease vein-to-vein time. We highlight five key abstracts from the 2023 ASCO Annual Meeting that showcase these exciting updates in BCMA-directed CAR-T cell therapies in RRMM.

Published: July 2023

Abstract
Background
Albumin infusion is the primary therapeutic strategy for septic patients with liver cirrhosis. Although recent studies have investigated the efficacy of albumin in the resuscitation stage of septic patients with liver cirrhosis, it remains unclear whether daily albumin administration can improve outcomes. Furthermore, the indications for initiating albumin therapy are not well defined.

Methods
Septic patients with liver cirrhosis were obtained from the Medical Information Mart for Intensive Care (MIMIC-IV 2.0) database. Marginal structural Cox models were employed to investigate the association between daily albumin infusion and 28-day mortality. We also aimed to explore under what circumstances enrolled patients could benefit most from albumin administration, based on the clinical parameters collected on the day of albumin infusion, including serum albumin concentration, serum lactate concentration, mean arterial pressure (MAP), and vasopressor dosage.

Results
A total of 2265 patients were included in the final analysis, of whom 1093 (48.3%) had received albumin treatment at least once. The overall 28-day mortality was 29.6%. After marginal structural modeling, daily albumin infusion was associated with a reduced risk of 28-day death (hazard ratio, 0.76; 95% CI 0.61–0.94). We found that patients benefit most from albumin infusion when initiated on the day of serum albumin concentration between 2.5 and 3.0 g/dL, serum lactate concentration greater than or equal to 2 mmol/L, MAP less than 60 mmHg, or vasopressor dosage between 0.2 and 0.3 mcg/kg/min (norepinephrine equivalent, NEE).

Conclusions
Albumin infusion is associated with a reduction in mortality in septic patients with liver cirrhosis under specific circumstances. Serum albumin concentration, serum lactate, MAP, and vasopressor dosage were found to be modifiers of treatment effectiveness and should be considered when deciding to initial albumin infusion.
Hypocalcemic tetany associated with simultaneous administration of cimetidine and nifedipine: a case report
Authors: Bezabih Yihienew M. , Bimrew Mekides A. , Bezabhe Woldesellassie M. 
Published: July 2023

Abstract
Background
Acute hypocalcemia is generally caused by a sudden drop in serum calcium ion and presents with a mild or severe form of tetany. Even though the occurrence of hypocalcemia is well documented with certain drugs such as calcium chelators, bisphosphonates, and cisplatin, it is a very unusual and poorly documented adverse event with cimetidine and nifedipine. Here, we present a case of severe hypocalcemic tetany during simultaneous administration of cimetidine and nifedipine in a hypertensive patient with dyspepsia.

Case presentation
A 46-year-old known human immunodeficiency virus patient from Ethiopia on antiretroviral therapy over the past 14 years presented to the emergency department with acute exacerbation of dyspepsia and hypertensive urgency. She was given intravenous cimetidine (400 mg) and oral nifedipine (30 mg) simultaneously. One hour after the administration of these two drugs, she developed severe hypocalcemic tetany with carpopedal spasm, involuntary plantar flexion, and muscle spasms. She also had severe retrosternal chest pain and shortness of breath. Her blood pressure was 160/110 mmHg during the attack and she had no skin changes, such as urticaria. She was immediately given 1 g of calcium gluconate intravenously over 30 minutes. The carpopedal spasm progressively decreased during calcium gluconate administration. An hour later, she completely regained voluntary movement of her fingers and feet. The chest pain persisted, but resolved over the next 12 hours. The patient was discharged home after 2 days of observation. This is an unusual adverse effect that needs caution during concomitant administration of these drugs.

Conclusions
Severe hypocalcemic tetany can occur with concomitant administration of cimetidine and nifedipine. Immediate treatment with calcium gluconate quickly reverses this adverse event. Concomitant administration of these drugs should be done with caution or be avoided if possible.

Abstract
Background
ALS is a heterogeneous disease in which different factors such as mitochondrial phenotypes act in combination with a genetic predisposition. This study addresses the question of whether homoplasmic (total mitochondrial genome of a sample is affected) and/or heteroplasmic mutations (wildtype and mutant mitochondrial DNA molecules coexist) might play a role in familial ALS. Blood was drawn from familial ALS patients with a possible maternal pattern of inheritance according to their pedigrees, which was compared to blood of ALS patients without maternal association as well as age-matched controls. In two cohorts, we analyzed the mitochondrial genome from whole blood or isolated white blood cells and platelets using a resequencing microarray (Affymetrix MitoChip v2.0) that is able to detect homoplasmic and heteroplasmic mitochondrial DNA mutations and allows the assessment of low-level heteroplasmy.

Results
We identified an increase in homoplasmic ND5 mutations, a subunit of respiratory chain complex I, in whole blood of ALS patients that allowed maternal inheritance. This effect was more pronounced in patients with bulbar onset. Heteroplasmic mutations were significantly increased in different mitochondrial genes in platelets of patients with possible maternal inheritance. No increase of low-level heteroplasmy was found in maternal ALS patients.

Conclusion
Our results indicate a contribution of homoplasmic ND5 mutations to maternally associated ALS with bulbar onset. Therefore, it might be conceivable that specific maternally transmitted rather than randomly acquired mitochondrial DNA mutations might contribute to the disease process. This stands in contrast with observations from Alzheimer’s and Parkinson’s diseases showing an age-dependent accumulation of unspecific mutations in mitochondrial DNA.
A study on ancient casting method via microstructures of impurities and copper found in bronze excavated from the Unified Silla Period (7th to 10th centuries)
Authors: Choi Jungeun 
Published: July 2023

Abstract
At the Hwangnyongsa temple site, which was founded in 633, at Dongdaebong Mountain in Korea, a large number of gilt-bronze artefacts have been excavated. Optical microscopy, X-ray fluorescence, scanning electron microscopy, energy dispersive X-ray spectroscopy, focused ion beam and transmission electron microscopy were used to identify the structure of specimen and impurities. This article investigated the impurities and copper grains in bronze Buddha robes from the Hwangnyongsa temple site to determine the ancient bronze craft technology in the Unified Silla period (seventh–tenth). The XRF results of the specimens indicated that they were made using an alloy of copper and tin, and gold plating was only added on the front side. The microstructure of the specimen was confirmed to be a recrystallized equiaxed hexagonal structure with twins and impurities. The EDS results of the impurities indicated the molar ratio of Cu:S was 2:1, and the electron diffraction pattern substantiated this result by indicating Cu2S (JCPDF 33-0490). The surface of the specimen consisted of a highlead layer and copper grains. It was hypothesized that the copper grains were formed by the reaction of Pb with the matte (Cu2S) during casting. Lead with black gas would aid in the production of high-quality bronze. The copper grains used were found in Silla, as they have been detected in Koryo bronze artefacts. Hence, it is plausible that the ancient artisans knew that lead provided good bronze quality during the casting process.
The making of dispensable subjects in the Simien Mountains National Park, Ethiopia: the relocation of the Gich community as an example
Authors: Endeshaw Marshet Girmay 
Published: July 2023

AbstractThe Simien Mountains National Park’s (SMNP) exoneration from the List of World Heritage Endangered is the recent story of the park. It is in September 2017 that the park has restored its place in UNESCO. Significant and sustainable reduction of human population within the park was one of the four basic standards set by the UNESCO World Heritage Commission in order to undo their decision. To fulfill UNESCO’s standard, the local government undertook relocations but inconsistently. By employing anthropological insights, this paper narrates the tale of the relocated Gich and Arkwazeye communities in the SMNP. The research used in-depth interview, discourse analysis and household surveys. Contrary to local government’s discourse on compensations, the Gich community suffered both socially and economically as a result of involuntary relocation. All the problems attached to this community are the result of the government’s non-participatory relocation plan which thus has created a dispensable subject. The Arkwazeye community, on the other hand, is experiencing a relatively stable life as they have maintained all social assets they have created as a community. The paper, therefore, recommends to the local government to individually take care of the lives of the Gich community.

AbstractBackgroundMigraine is believed to affect over 20% of people at some point in their lives. The presence of sexual dysfunction in migraine sufferers can cause lack of self-confidence and divorces. The aim of this work is to study sexual dysfunction in migraine headache patients.MethodsThe study was carried out at Tanta University Hospital. The study included married patients who visited our hospital clinic and have had episodic or chronic migraine headaches and another group of age and sex matched healthy subjects will be recurited as a control group. Our interview includes questions for disease duration, severity and frequency of headache attacks and attack duration. questionnaire. the Arabic Version of the Migraine Disability Assessment Scale and Beck depression inventory. Sexual function will be evaluated by an Arabic version of Arizona sexual experience scale.ResultsThe ASEX score showed high significant changes between migraine patients and healthy subjects. These changes were reconfirmed when comparing male patients to healthy subjects or female patients to healthy subjects.Despite there was no significant difference regarding total ASEX score between bot male and female patients with migraine there was significant differences in the items of derive, erection/lubrication and satisfaction between them. In patients with migraine the total ASEX score was correlated with the MIDAS, Beck depression inventory, Beck anxiety inventory; but not with the age of patients or headache duration.ConclusionsSexual dysfunction is a common finding in migrine patients which is poorly evaluted in the clinical sitting.
