Published: August 2023

AbstractChronic apical periodontitis is a prevalent oral disease characterized by bone loss, and its underlying mechanisms remain unclear. This study aimed to investigate the role and mechanism of the serine protease GZMA in osteoclasts during chronic apical periodontitis. To address this, we employed crRNA/Cas13d to inhibit GZMA expression and examined its impact on osteoclast behavior. Our findings revealed that GZMA plays a significant role in promoting osteoclast cell proliferation while inhibiting cell apoptosis. Additionally, the inhibition of GZMA led to a notable increase in miR-25-3p expression, which, in turn, downregulated the expression of TGF-β. Consequently, the reduction in TGF-β expression led to a decrease in PAR1 expression within the PARs pathway. These results suggest that GZMA might serve as a promising therapeutic target for the treatment of chronic apical periodontitis. Furthermore, our study highlights the potential of targeting GZMA using crRNA/Cas13d as a valuable approach for future therapeutic interventions.

Published: August 2023

Abstract
Background
The impact of a perturbation, over-expression, or repression of a key node on an organism, can be modelled based on a regulatory and/or metabolic network. Integration of these two networks could improve our global understanding of biological mechanisms triggered by a perturbation. This study focuses on improving the modelling of the regulatory network to facilitate a possible integration with the metabolic network. Previously proposed methods that study this problem fail to deal with a real-size regulatory network, computing predictions sensitive to perturbation and quantifying the predicted species behaviour more finely.

Results
To address previously mentioned limitations, we develop a new method based on Answer Set Programming, MajS. It takes a regulatory network and a discrete partial set of observations as input. MajS tests the consistency between the input data, proposes minimal repairs on the network to establish consistency, and finally computes weighted and signed predictions over the network species. We tested MajS by comparing the HIF-1 signalling pathway with two gene-expression datasets. Our results show that MajS can predict 100% of unobserved species. When comparing MajS with two similar (discrete and quantitative) tools, we observed that compared with the discrete tool, MajS proposes a better coverage of the unobserved species, is more sensitive to system perturbations, and proposes predictions closer to real data. Compared to the quantitative tool, MajS provides more refined discrete predictions that agree with the dynamic proposed by the quantitative tool.

Conclusions
MajS is a new method to test the consistency between a regulatory network and a dataset that provides computational predictions on unobserved network species. It provides fine-grained discrete predictions by outputting the weight of the predicted sign as a piece of additional information. MajS’ output, thanks to its weight, could easily be integrated with metabolic network modelling.

Authors: Jian Minyu , Liu Haiyang , Liang Fa , Ma Bo , Wang Lianjie , Zhou Yang , Qiao Hui , Han Ruquan , Wang Chengwei 
Published: August 2023

Abstract
Background
Partial neuromuscular blockade (NMB) has been applied for some surgeries to reduce bleeding and prevent patient movement for spinal surgery. Sugammadex selectively binds to rocuronium in the plasma and consequently lowers the rocuronium concentration at the neuromuscular junction. In this study, we aimed to observe whether the success rate of transcranial motor-evoked potential (TceMEP) can be increased by sugammadex compared with partial NMB during spinal surgery.

Methods
Patients who underwent elective spinal surgery with TceMEP monitoring were randomly assigned to the sugammadex group and control group. Rocuronium was continuously infused to maintain the train of four counts (TOFc) = 2. The sugammadex group discontinued rocuronium infusion at the time of TceMEP monitoring and was infused with 2 mg/kg sugammadex; the control group was infused with the same dose of saline.

Results
A total of 171 patients were included. The success rate of TceMEP monitoring in the sugammadex group was significantly higher than that in the control group. TceMEP amplitudes were greater in the sugammadex group than in the control group at 5 min, 10 min, and 20 min after the start of motor-evoked potential monitoring. The latencies of upper extremity TceMEPs monitoring showed no difference between groups. TOF ratios were greater in the sugammadex group at 5 min, 10 min, and 20 min after the start of motor-evoked potential monitoring. There were no adverse effects caused by sugammadex.

Conclusions
Sugammadex can improve the success rate of motor-evoked potential monitoring compared with moderate neuromuscular blockade induced by continuous infusion of rocuronium in spinal surgery.

Authors: Elshaikh Usra , Sheik Rayan , Saeed Raghad Khaled Mohammad , Chivese Tawanda , Alsayed Hassan Diana 
Published: August 2023

Abstract
Background
Older adults are at an increased risk for mental health issues, yet they are less likely to seek professional help. This systematic review aims to identify and summarize literature on the barriers and facilitators that older adults face when seeking professional mental health help.

Methods
A comprehensive literature search was conducted using multiple databases including PubMed-Medline, EMBASE, ProQuest central, CINAHL and Scopus to identify relevant studies published between 2010 and 2021 that focused on barriers and/or facilitators to seeking help for depression, anxiety, and psychological distress among older adults aged 65 years or older. Studies’ risk of bias was assessed using the Newcastle–Ottawa Scale and results of studies were synthesized guided by the methodological framework of Rodgers and colleagues.

Results
A total of eight cross-sectional studies, from Australia, United States, Mexico, Netherlands, and Malaysia met the inclusion criteria for this review. Included studies reported that the majority of their participants had anxiety or depression, yet they exhibited a preference for informal mental health help over professional help. Stigma, negative beliefs about mental health professional services, and cost were the most reported barriers. Main reported facilitators were prior positive experience with mental health services and high socioeconomic status.

Conclusion
Older adults are in need of interventions normalizing mental health help seeking and ensuring these services are accessible in terms of costs. This should be the focus of policy makers, healthcare providers, and public health practitioners working with older adults.

Authors: Huang Jieen , Chen Yanzhu , Li Ming , Xie Shujin , Tong Huasheng , Guo Zhusheng , Chen Yi 
Published: August 2023

Abstract
Background
Hypervirulent Klebsiella pneumoniae (hvKP) is emerging globally and can cause various, severe infections in healthy individuals. However, the clinical manifestations of hvKP infections are nonspecific, and there is no gold standard for differentiating hvKP strains. Our objective was to develop prognostic models for estimating severity of disease and predicting 30-day all-cause mortality in patients with hvKP infections.

Methods
We enrolled 116 patients diagnosed with hvKP infections and obtained their demographic and clinical data. Taking septic shock and acute respiratory distress syndrome (ARDS) as the primary outcomes for disease severity and 30-day all-cause mortality as the primary outcome for clinical prognosis, we explored the influencing factors and constructed prognostic models.

Results
The results showed that increased Acute Physiologic and Chronic Health Evaluation (APACHE) II score [odds ratio (OR) = 1.146; 95% confidence interval (CI), 1.059–1.240], decreased albumin (ALB) level (OR = 0.867; 95% CI, 0.758–0.990), diabetes (OR = 9.591; 95% CI, 1.766–52.075) and high procalcitonin (PCT) level (OR = 1.051; 95%CI, 1.005–1.099) were independent risk factors for septic shock. And increased APACHE II score (OR = 1.254; 95% CI, 1.110–1.147), community-acquired pneumonia (CAP) (OR = 11.880; 95% CI, 2.524–55.923), and extrahepatic lesion involved (OR = 14.718; 95% CI, 1.005–215.502) were independent risk factors for ARDS. Prognostic models were constructed for disease severity with these independent risk factors, and the models were significantly correlated with continuous renal replacement therapy (CRRT) duration, vasopressor duration, mechanical ventilator duration and length of ICU stay. The 30-day all-cause mortality rate in our study was 28.4%. Younger age [hazard ratio (HR) = 0.947; 95% CI, 0.923–0.973)], increased APACHE II score (HR = 1.157; 95% CI, 1.110–1.207), and decreased ALB level (HR = 0.924; 95% CI, 0.869–0.983) were the independent risk factors for 30-day all-cause mortality. A prediction model for 30-day mortality was constructed, which had a good validation effect.

Conclusions
We developed validated models containing routine clinical parameters for estimating disease severity and predicting 30-day mortality in patients with hvKP infections and confirmed their calibration. The models may assist clinicians in assessing disease severity and estimating the 30-day mortality early.
Effects of reduced follicle-stimulating hormone dosage before human chorionic gonadotropin trigger on in vitro fertilization outcomes
Authors: Ou Zhanhui , Du Jing , Liu Nengqing , Li Jieliang , Lin Xiufeng 
Published: August 2023

Abstract
Objective
To determine whether a reduced dose of follicle-stimulating hormone (FSH) before human chorionic gonadotropin (hCG) trigger during ovarian stimulation can affect in vitro fertilization (IVF) outcomes.

Methods
This study included 347 patients with a normal ovarian response who received a reduced dose of FSH before hCG trigger for 2–3 days (Group A) and 671 patients who did not receive a reduced dose (Group B) from a university-affiliated IVF center between January 2021 and December 2022. The primary endpoint was estrogen (E2) and progesterone (P) levels on the day of hCG trigger, fresh embryo transfer cycles, laboratory outcomes, and clinical outcomes between the two groups.

Results
On the day of hCG trigger, Group A had significantly lower E2 and P levels than those in Group B (3454.95 ± 1708.14 pg/mL versus 3798.70 ± 1774.26 pg/mL, p = 0.003; and 1.23 ± 0.53 ng/mL versus 1.37 ± 0.59 ng/mL, p < 0.001, respectively). The proportion of patients with P levels ≥ 1.5 ng/mL was 22.48% in Group A compared to 34.58% in Group B (p < 0.001), while the proportion of patients with E2 ≥ 5000 pg/mL was 15.27% in Group A compared to 25.93% in Group B (p < 0.001). The fresh embryo-transfer cycle rate in Group A was higher than that in group B (54.47% and 32.64%, respectively; p < 0.001). Despite the reduction in FSH dosage, there were no significant differences between groups regarding the number of oocytes retrieved, total number of mature oocytes, normal fertilization rate, cleavage rate, Day 3 top-quality rate, implantation rate, pregnancy rate per cycle, and early pregnancy loss rate.

Conclusion
While a reduced dose of FSH prior to hCG trigger during ovarian stimulation did not significantly affect IVF outcomes, it was associated with lower E2 and P levels, resulting in fewer cycles with E2 ≥ 5000 pg/mL and P ≥ 1.5 ng/mL on the day of the hCG trigger.
A novel smoothed (SMO) point mutation in congenital tibial hemimelia: a case report
Authors: Yang Xiaodong , Pu Siyu , Xiang Bo , Tang Xueyang , Chen Jing 
Published: August 2023

Abstract
Background
Congenital tibial hemimelia (CTH [MIM: 275220]) is a rare congenital limb deficiency that manifests as a shortened, curved, dysplastic or absent tibia with polydactyly. In previous studies, mutations of a distant sonic hedgehog (SHH) cis-regulator (ZRS) and a Shh repressor (GLI3) were identified.

Case presentation
Here, we admitted a 20-month-old boy who manifested with right tibial deformity, varus foot, ankle dislocation, and ipsilateral preaxial polydactyly. After genetic sequencing and data analysis, the results revealed a 443 A > G mutation in the father and a 536 C > T mutation in the mother in exon 2 of the Smoothed (SMO) gene at 7q32.1, with the coexistence of both mutant alleles in the proband/patient.

Conclusions
Our report suggests that even though not previously reported, SMO mutations may be associated with limb anomalies such as tibial hemimelia via Hh signaling in humans and has implications for genetic counseling.
Using the Health Belief Model to assess COVID-19 perceptions and behaviours among a group of Egyptian adults: a cross-sectional study
Authors: Boulos Dina N. K. , Hassan Azza Mohammed 
Published: August 2023

Abstract
Background
It is crucial to study the public’s perceptions and behaviour during a pandemic as this will be the driving force for practicing recommended precautions. The current study aimed to identify perceptions of a group of Egyptian adults to COVID-19 using the Health Belief Model (HBM), to measure self-reported practice of preventive behaviours and to identify influencing factors.

Methods
Cross sectional study was used, including Egyptian adults aged 18 + years. A structured anonymous online questionnaire was used including: a demographic section, the modified MERS- CoV Health Belief Model scale after addition of questions related to COVID-19 and questions on preventive behaviours to COVID-19.

Results
Of the 532 study participants, 28.6% were males, age ranges (18 to 74 years). There was a statistically significant positive correlation between total practice score and all COVID-19 Health Belief Model constructs total scores except for perceived barriers score showing negative correlation (P value < 0.05). Linear regression analysis showed that older age, male gender and living inside Cairo were associated with lower practice score (P value < 0.01).

Conclusions
Increased perceived susceptibility, perceived benefits, cues to action and perceived self-efficacy scores were associated with higher practice score in the current study. Additionally, results revealed that social media and websites can play an important role in shaping risk perception in the community. Stressing risk perception and efficacy beliefs prevention message can drive people to practice preventive behaviors.
School health systems under strain: an example of COVID-19 experiences & burnout among school health staff in Pima County, Arizona
Authors: Wilson Amanda M. , Ravi Priyanka , Pargas Nicole T. , Gerald Lynn B. , Lowe Ashley A. 
Published: August 2023

Abstract
Background
School health staff lead and provide a variety of care for children in schools. As school districts have navigated the COVID-19 pandemic, school health staff have faced unprecedented challenges in protecting the health of students and school staff. Our objective was to qualitatively characterize these pandemic challenges and experiences of school health staff in Pima County, Arizona to identify gaps in school health staff support for improving future emergency preparedness.

Methods
We conducted two focus group discussions (FGDs) with 48 school health staff in Pima County, Arizona in two school districts using a discussion guide including ten open-ended questions. The FGDs were audio recorded and transcribed verbatim. We used the socioecological model (SEM) to organize the thematic analysis and generate codes and themes; data were analyzed using Atlas.ti software.

Findings
The pandemic has significantly challenged school health staff with new pandemic-related job tasks: managing isolation, vaccination, and developing/implementing new and evolving COVID-19 guidelines. School health staff also reported increased stress related to interactions with parents and school administration as well as frustrations with rapid changes to guidance from the health department and policy makers. A common issue was not having enough staff or resources to complete regular job responsibilities, such as providing care for students with non-COVID-19 related health issues.

Conclusions
Increased workload for school health staff resulted in physical burnout, mental distress, and disruption of core functions with long term implications for children’s health. These focus groups highlight the need for improved emergency preparedness in schools during pandemics or infectious disease outbreaks. These include basic infrastructure changes (e.g., personnel support from health departments for tasks such as contact tracing to enable school nurses to continue core functions), and increased funding to allow for hazard pay and more school health personnel during emergency situations. In addition, basic school health infrastructure is lacking, and we should include a licensed school health nurse in every school.

Authors: Gotardelo Marcele Pereira Silvestre , Rodrigues Allana Lima Moreira , Quaresma Fernando Rodrigues Peixoto , Pontes-Silva André , Maciel Erika da Silva 
Published: August 2023

Abstract
Background
Studies investigating vulnerable populations have shown that work-related musculoskeletal disorders have a negative impact on quality of life. However, no study has examined the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations.

Objective
To describe the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations.

Methods
Cross-sectional study. We used the ABEP questionnaire, the World Health Organization Quality of Life, the Nordic Musculoskeletal Disorders Questionnaire, the Perceived Stress Scale, and a self-report questionnaire to determine morning-evening in human circadian rhythms (chronotype assessment). To reduce the possibility of information bias, we provided prior training in the use of the instruments and created an electronic database that was filled out in duplicate (in cases of disagreement, a third researcher was consulted). We tested the normality of the data using the Shapiro–Wilk test.

Results
The sample consisted of 132 participants, but there was a sample loss of 41.6% (final sample n = 77). We observed the predominance of those who worked from 6 to 8 h/day, rest of 1 h during the working day, from 1 to 10 years of service and only 1 employment relationship. Regarding the quality of life, we observed a worse result in the domain related to the environment, as well as a stress level of 15.43 (± 7.52) with a maximum of 30. Finally, we observed the presence of pain self-reported by the artisanal fishermen in several regions of the body, lumbar being the most mentioned.

Conclusion
The neck, shoulders, arms, elbows, forearms, wrists, back, lumbar spine, and lower limbs are the most common parts of the body affected by work-related musculoskeletal disorders in artisanal fishermen.

Abstract
Objective
This study aims to demonstrate the cellular composition and underlying mechanisms in subchondral bone marrow lesions (BMLs) of knee osteoarthritis (OA).

Methods
BMLs were assessed by MRI Osteoarthritis Knee Score (MOAKS)≥2. Bulk RNA-sequencing (bulk-seq) and BML-specific differentially expressed genes (DEGs) analysis were performed among subchondral bone samples (including OA-BML=3, paired OA-NBML=3; non-OA=3). The hub genes of BMLs were identified by verifying in independent datasets and multiple bioinformatic analyses. To further estimate cell-type composition of subchondral bone, we utilized two newly developed deconvolution algorithms (MuSiC, MCP-counter) in transcriptomic datasets, based on signatures from open-accessed single-cell RNA sequencing (scRNA-seq). Finally, competing endogenous RNA (ceRNA) and transcription factor (TF) networks were constructed through multiple predictive databases, and validated by public non-coding RNA profiles.

Results
A total of 86 BML-specific DEGs (up 79, down 7) were identified. IL11 and VCAN were identified as core hub genes. The “has-miR-424-5p/lncRNA PVT1” was determined as crucial network, targeting IL11 and VCAN, respectively. More importantly, two deconvolution algorithms produced approximate estimations of cell-type composition, and the cluster of heterotopic-chondrocyte was discovered abundant in BMLs, and positively correlated with the expression of hub genes.

Conclusion
IL11 and VCAN were identified as the core hub genes of BMLs, and their molecular networks were determined as well. We profiled the characteristics of subchondral bone at single-cell level and determined that the heterotopic-chondrocyte was abundant in BMLs and was closely linked to IL11 and VCAN. Our study may provide new insights into the microenvironment and pathological molecular mechanism of BMLs, and could lead to novel therapeutic strategies.
