Background

Since clinically relevant postoperative pancreatic fistula (CR-POPF) can cause intra-abdominal hemorrhage and abscesses, leading to surgery-related deaths after pancreaticoduodenectomy (PD), its preoperative prediction is important to develop strategies for surgical procedures and perioperative management. This study aimed to establish a novel prediction model for CR-POPF using preoperative markers.

Methods

On a training set of 180 patients who underwent PD at the Yamaguchi University Hospital, a combination of CR-POPF predictors were explored using the leave-one-out method with a unique discrete Bayes classifier. This predictive model was confirmed using a validation set of 366 patients who underwent PD at the Osaka University Hospital.

Results

In the training set, CR-POPF occurred in 60 (33%)　of 180 patients and 130 (36%)　of 366 patients in the validation set using selected markers. In patients with pancreatic ductal adenocarcinoma (PDAC), the main pancreatic duct (MPD) index showed the highest prognostic performance and could differentiate CR-POPF with 87% sensitivity and 81% specificity among 84 patients in the training set. In the validation set, the sensitivity and specificity of the MPD index-based model for 130 PDAC samples were 93% and 87%, respectively. In patients with non-PDAC, the MPD index/body mass index (BMI) combination showed the highest prognostic performance and could differentiate CR-POPF with 84% sensitivity and 57% specificity among 96 patients in the training set. In the validation set, the sensitivity and specificity of the MPD index/BMI-based model for 236 non-PDAC samples were 85% and 53%, respectively.

Conclusion

We developed a novel prediction model for pancreatic fistulas after PD using only preoperative markers. The MPD index and MPD index/BMI combination will be useful for CR-POPF assessment in PDAC and non-PDAC samples, respectively.

Introduction

Robotic ureteral reconstruction (RUR) has been widely used to treat ureteral diseases. To summarize the surgical techniques, complications, and outcomes following RUR, as well as to compare data on RUR with open and laparoscopic ureteral reconstruction.

Methods

Our systematic review was registered on the PROSPERO (CRD42022309364) database. The PubMed, Cochrane and Embase databases were searched for publications in English on 06-Feb-2022. Randomised-controlled trials (RCTs) or non-randomised cohort studies with sample size ≥ 10 cases were included.

Results

A total of 23 studies were included involving 996 patients and 1004 ureters from 13 non-comparative, and 10 retrospective comparative studies. No RCT study of RUR was reported. The success rate was reported ≥ 90% in 15 studies. Four studies reported 85–90% success rate. Meta-analyses for comparative studies showed that RUR had significantly lower estimated blood loss (EBL) (P = 0.006) and shorter length of stay (LOS) (P < 0.001) than the open approach. RUR had shorter operative time than laparoscopic surgery (P < 0.001).

Conclusions

RUR is associated with lower EBL and shorter LOS than the open approach, and shorter operative time than the laparoscopic approach for the treatment of benign ureteral strictures. However, further studies and more evidence are needed to determine whether RUR is more superior.

Published: October 2023

Background

Abnormal uterine bleeding associated with ovulatory dysfunction (AUB-O) is a typical gynecological disease that can affect women of various ages. Being able to identify women at risk of AUB-O could allow physicians to take timely action. This study aimed to identify the influencing factors of AUB-O in Chinese women, and then develop and validate a predictive model.

Methods

In this multicenter case–control study, 391 women with AUB-O and 838 controls who came from nine hospitals in Zhejiang province were recruited between April 2019 and January 2022. All the participants completed a structured questionnaire including general characteristics, lifestyle and habits, menstrual and reproductive history, and previous diseases. The predictive model was developed on a group of 822 women and validated on a group of 407 women. Logistic regression was adopted to investigate the influencing factors and develop the model, and validation was then performed.

Results

The independent predictive factors of AUB-O were age (OR 1.073, 95% CI 1.046—1.102, P < 0.001), body mass index (OR 1.081, 95% CI 1.016—1.151, P = 0.015), systolic blood pressure (OR 1.016, 95% CI 1.002—1.029, P = 0.023), residence (OR 2.451, 95% CI 1.727—3.478, P < 0.001), plant-based diet (OR 2.306, 95% CI 1.415—3.759, P < 0.001), fruits eating (OR 1.887, 95% CI 1.282—2.776, P = 0.001), daily sleep duration (OR 0.819; 95% CI 0.708—0.946, P = 0.007), multiparous (parity = 1, OR 0.424, 95% CI 0.239—0.752, P = 0.003; parity > 1, OR 0.450, 95% CI 0.247—0.822, P = 0.009), and history of ovarian cyst (OR 1.880, 95% CI 1.305—2.710, P < 0.001). The predictive ability (area under the curve) in the development group was 0.77 (95% CI 0.74—0.81), while in the validation group it was 0.73 (95% CI 0.67—0.79). The calibration curve was in high coincidence with the standard curve in the development group, and similar to the validation group. A tool for AUB-O risk calculation was created.

Conclusions

Nine influencing factors and a predictive model were proposed in this study, which could identify women who are at high risk of developing AUB-O. This finding highlights the importance of early screening and the lifelong management of ovulatory disorders for women.

Published: October 2023

Background

New disease-modifying ways to treat Parkinson’s disease (PD) may soon become a reality with intracerebral transplantation of cell products produced from human embryonic stem cells (hESCs). The aim of this study was to assess what factors influence preferences of patients with PD regarding stem-cell based therapies to treat PD in the future.

Methods

Patients with PD were invited to complete a web-based discrete choice experiment to assess the importance of the following attributes: (i) type of treatment, (ii) aim of treatment, (iii) available knowledge of the different types of treatments, (iv) effect on symptoms, and (v) risk for severe side effects. Latent class conditional logistic regression models were used to determine preference estimates and heterogeneity in respondents’ preferences.

Results

A substantial difference in respondents’ preferences was observed in three latent preference patterns (classes). “Effect on symptoms” was the most important attribute in class 1, closely followed by “type of treatment,” with medications as preferred to other treatment alternatives. Effect on symptoms was also the most important attribute in class 2, with treatment with hESCs preferred over other treatment alternatives. Likewise for class 3, that mainly focused on “type of treatment” in the decision-making. Respondents’ class membership was influenced by their experience in treatment, side effects, and advanced treatment therapy as well as religious beliefs.

Conclusions

Most of the respondents would accept a treatment with products emanating from hESCs, regardless of views on the moral status of embryos. Preferences of patients with PD may provide guidance in clinical decision-making regarding treatments deriving from stem cells.
Crosstalk between mitochondrial biogenesis and mitophagy to maintain mitochondrial homeostasis
Authors: Liu Lei , Li Yanjun , Chen Guo , Chen Quan
Published: October 2023

Mitochondrial mass and quality are tightly regulated by two essential and opposing mechanisms, mitochondrial biogenesis (mitobiogenesis) and mitophagy, in response to cellular energy needs and other cellular and environmental cues. Great strides have been made to uncover key regulators of these complex processes. Emerging evidence has shown that there exists a tight coordination between mitophagy and mitobiogenesis, and their defects may cause many human diseases. In this review, we will first summarize the recent advances made in the discovery of molecular regulations of mitobiogenesis and mitophagy and then focus on the mechanism and signaling pathways involved in the simultaneous regulation of mitobiogenesis and mitophagy in the response of tissue or cultured cells to energy needs, stress, or pathophysiological conditions. Further studies of the crosstalk of these two opposing processes at the molecular level will provide a better understanding of how the cell maintains optimal cellular fitness and function under physiological and pathophysiological conditions, which holds promise for fighting aging and aging-related diseases.
Targeting Rev-Erbα to protect against ischemia-reperfusion-induced acute lung injury in rats
Authors: Chu Shi-Jye , Liao Wen-I , Pao Hsin-Ping , Wu Shu-Yu , Tang Shih-En
Published: October 2023

Background

The dysregulation of local circadian clock has been implicated in the pathogenesis of a broad spectrum of diseases. However, the pathophysiological role of intrinsic circadian clocks Rev-Erbα in ischemia-reperfusion (IR)-induced acute lung injury (ALI) remains unclear.

Methods

The IR-ALI model was established by subjecting isolated perfused rat lungs to 40 min of ischemia followed by 60 min of reperfusion. Rats were randomly assigned to one of six groups: control, control + SR9009 (Rev-Erbα agonist, 50 mg/kg), IR, and IR + SR9009 at one of three dosages (12.5, 25, 50 mg/kg). Bronchoalveolar lavage fluids (BALF) and lung tissues were obtained and analyzed. In vitro experiments utilized mouse lung epithelial cells (MLE-12) exposed to hypoxia-reoxygenation (HR) and pretreated with SR9009 (10 µM/L) and Rev-Erbα siRNA.

Results

SR9009 exhibited a dose-dependent reduction in lung edema in IR-ALI. It significantly inhibited the production of TNF-α, IL-6, and CINC-1 in BALF. Moreover, SR9009 treatment restored suppressed IκB-α levels and reduced nuclear NF-κB p65 levels in lung tissues. In addition, a SR9009 mitigated IR-induced apoptosis and mitogen-activated protein kinase (MAPK) activation in injured lung tissue. Finally, treatment with Rev-Erbα antagonist SR8278 abolished the protective action of SR9009. In vitro analyses showed that SR9009 attenuated NF-κB activation and KC/CXCL-1 levels in MLE-12 cells exposed to HR, and these effects were significantly abrogated by Rev-Erbα siRNA.

Conclusions

The findings suggest that SR9009 exerts protective effects against IR-ALI in a Rev-Erbα-dependent manner. SR9009 may provide a novel adjuvant therapeutic approach for IR-ALI.

Published: October 2023

Background

Evidence-informed policymaking (EIPM) requires a set of individual and organizational knowledge, skills and attitudes that should be articulated with background factors and needs. In this regard, the development of an EIPM competency profile is important to support the diagnosis, planning and implementation of EIPM.

Purpose

To present the process and outcomes of the development of an EIPM competency profile by an expert committee, to be applied in different contexts of the Brazilian Health System.

Methods

A committee of experts in EIPM shared different views, experiences and opinions to develop an EIPM competency profile for Brazil. In six consensus workshops mediated by facilitators, the committee defined from macro problems to key actions and performances essential for the competency profile. The development steps consisted of: (1) Constitution of the committee, including researchers, professionals with practical experience, managers, and educators; (2) Development of a rapid review on EIPM competency profiles; (3) Agreement on commitments and responsibilities in the processes; (4) Identification and definition of macro problems relating to the scope of the competency profile; and (5) Outlining of general and specific capacities, to be incorporated into the competency profile, categorized by key actions.

Results

The development of the EIPM competency profile was guided by the following macro problems: (1) lack of systematic and transparent decision-making processes in health policy management; (2) underdeveloped institutional capacity for knowledge management and translation; and (3) incipient use of scientific evidence in the formulation and implementation of health policies. A general framework of key actions and performances of the EIPM Competency Profile for Brazil was developed, including 42 specific and general key actions distributed by area of activity (Health Management, Scientific Research, Civil Society, Knowledge Translation, and Cross-sectional areas).

Conclusions

The competency profile presented in this article can be used in different contexts as a key tool for the institutionalization of EIPM.

Published: October 2023

Background

Physiotherapy appears as a promising therapy option for patients with Juvenile Idiopathic Arthritis (JIA) [1, 2], but the effects of physiotherapy and jaw exercises on JIA-related orofacial symptoms remain unknown [3]. The aim of this proof-of-concept study was to assess the impact of orofacial physiotherapy and home-exercise programs in patients with JIA and temporomandibular joint (TMJ) involvement.

Methods

Twelve patients with JIA and TMJ involvement received a treatment of physiotherapy, complemented by prescribed home exercises spanning over eight weeks. Orofacial symptoms and dysfunction were monitored pre-treatment, during treatment, after treatment, and at a three-months follow-up.

Results

Orofacial pain frequency and intensity significantly decreased during the course of the treatment (p = 0.009 and p = 0.006), with further reductions observed at the three-month follow-up (p = 0.007 and p = 0.002). During treatment, the mandibular function improved significantly in terms of maximal mouth opening capacity, laterotrusion, and protrusion.

Conclusions

This proof-of-concept study shows favourable effects of physiotherapy and home excercises in the management of JIA-related orofacial symptoms and dysfunctions.
Performance of interferon-gamma levels may lead to earlier diagnosing macrophage activation syndrome complicating systemic juvenile idiopathic arthritis
Authors: Lu Meiping , Teng Liping , Xu Yiping , Xu Xuefeng
Published: October 2023

Macrophage activation syndrome (MAS) is a severe, potentially fatal complication of rheumatic diseases, predominantly in systemic juvenile idiopathic arthritis (SJIA), and is considered as an autoinflammatory disease. Specific cytokine profiles could play a pivotal role in this inflammatory response. Gram-negative bacteremia, bacterial pneumonia, Kawasaki disease, and active SJIA exhibited similar cytokine profiles with elevated interleukin-6 (IL-6) and/or IL-10, further suggesting a correlation between them. Only when JIA is complicated by MAS can increased interferon-γ (IFN-γ) levels be observed. Therefore, increased serum IFN-γ levels could contribute to early diagnosing MAS in patients with SJIA in combination with other variables such as serum ferritin. A prospective multi-center study will be performed to further confirm the role of IFN-γ in the early recognition of MAS in SJIA.

Published: October 2023

Background

Pre-existing diabetes mellitus (DM) is a challenging pregnancy complication as poor glycemic control is associated with adverse maternal and fetal outcomes. In this study, we aimed to investigate DM-related knowledge, attitudes, preconception care practices, and contraceptive prevalence in women with DM.

Methods

This descriptive cross-sectional survey was conducted among reproductive-aged Thai women receiving DM treatment at King Chulalongkorn Memorial Hospital between August 1, 2021, and June 30, 2022. Patients with DM who were not pregnant or trying to conceive and could be contacted via the phone were included and a validated self-administered questionnaire was distributed electronically.

Results

A total of 238 participants were included in the final analysis, yielding 69.4% response rates. The mean (standard deviation) score for knowledge of pregnancy planning and pregnancy-related risks was 6.8 (3.5) out of 15. Only about half of the participants had discussed pregnancy planning with their physicians. Multivariable analysis showed that younger age at DM diagnosis, non-Buddhism, married, higher education, and medical personnel were significantly associated with higher knowledge scores. Women aged > 45 years and those with higher practice scores had significantly higher adjusted odds of using highly effective contraception; the most common methods included male condoms and combined oral contraceptive pills. There was an unmet need for contraception in 9.5% of women with DM.

Conclusions

Although highly effective contraception is safe for patients with DM, only about half of our participants used tier one or two contraceptives or had received consultation regarding preconception planning. There was a notable gap in care coordination among specialists; integrating reproductive healthcare into DM therapy would improve access to preconception care.

Published: October 2023

Background

Silicosis is an important occupational disease caused by inhalation of free silica and is characterized by persistent pulmonary inflammation, subsequent fibrosis and lung dysfunction. Until now, there has been no effective treatment for the disease due to the complexity of pathogenesis. Fermented cordyceps powder (FCP) has a similar effect to natural cordyceps in tonifying the lung and kidney. It has started to be used in the adjuvant treatment of silicosis. This work aimed to verify the protective effects of FCP against silicosis, and to explore the related mechanism.

Methods

Wistar rats were randomly divided into four groups including the saline-instilled group, the silica-exposed group, the silica + FCP (300 mg/kg) group and the silica + FCP (600 mg/kg) group. Silicosis rat models were constructed by intratracheal instillation of silica (50 mg). Rats in the FCP intervention groups received the corresponding dose of FCP daily by intragastric gavage. Rats were sacrificed on days 7, 28 and 56 after treatment, then samples were collected for further analysis.

Results

FCP intervention reduced the infiltration of inflammatory cells and the concentration of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) at days 7, 28, 56, and decreased the expression of collagen, α-smooth muscle actin (α-SMA) and fibronectin (FN) at days 28 and 56 in the lung of silicosis rats. FCP also decreased the immune response of Th1 and Th17 at days 7, 28, 56 and inhibited the enhancement of the Th2 response at day 56.

Conclusions

FCP intervention could alleviate silica-induced pulmonary inflammation and fibrosis, the protective effect may be achieved by reducing Th1 and Th17 immune responses and inhibiting the enhancement of the Th2 response.
Targeted literature review exploring the predictive value of estimated glomerular filtration rate and left ventricular mass index as indicators of clinical events in Fabry disease
Authors: Haycroft Ben , Stevenson Abigail , Stork Richard , Gaffney Stuart , Morgan Philip , Patterson Karl , Jovanovic Ana
Published: October 2023

Background

Fabry disease is a rare, progressive X-linked lysosomal storage disorder. It is caused by mutations in the GLA gene resulting in deficiency of α-galactosidase A (α-Gal A), leading to peripheral neuropathy, cardiovascular disease, stroke, end-stage renal disease, gastrointestinal disorders and premature death. Given the long-term nature of disease progression, trials in Fabry disease are often not powered to capture these clinical events. Clinical measures such as estimated glomerular filtration rate (eGFR) and left ventricular mass index (LVMI) are often captured instead. eGFR and LVMI are believed to be associated with long-term Fabry disease clinical events of interest, but the precise relationships are unclear.

Objective

We aimed to identify published literature exploring the link between eGFR/LVMI and long-term clinical events in Fabry disease.

Methods

A comprehensive literature search was conducted in Embase® and MEDLINE® (using Embase.com), and a targeted literature review was conducted. Studies reporting a quantitative relationship between eGFR and/or LVMI and clinical events in Fabry disease were extracted, and narrative synthesis was conducted to understand these predictive relationships.

Results

Eight studies, consisting of seven patient-level retrospective analyses plus one prospective cohort study, met the inclusion criteria. Seven of these studies reported eGFR and six reported LVMI, with five reporting both. All studies presented results for either a composite measure including a range of key Fabry disease clinical events, or a composite outcome that included at least one key Fabry disease clinical event. All studies employed Cox proportional hazards survival modelling. The studies consistently reported that eGFR and LVMI are predictors of key clinical events in Fabry disease, with the findings remaining consistent regardless of the therapy received by patients in the studies.

Conclusions

The evidence identified suggests that eGFR and LVMI outcomes may be appropriate indicators for long-term clinical events in Fabry disease, and all identified papers implied the same directional relationship. However, additional research is needed to further understand the specific details of these relationships and to quantify them.
A fast non-parametric test of association for multiple traits
Authors: Garrido-Martín Diego , Calvo Miquel , Reverter Ferran , Guigó Roderic
Published: October 2023

The increasing availability of multidimensional phenotypic data in large cohorts of genotyped individuals requires efficient methods to identify genetic effects on multiple traits. Permutational multivariate analysis of variance (PERMANOVA) offers a powerful non-parametric approach. However, it relies on permutations to assess significance, which hinders the analysis of large datasets. Here, we derive the limiting null distribution of the PERMANOVA test statistic, providing a framework for the fast computation of asymptotic p values. Our asymptotic test presents controlled type I error and high power, often outperforming parametric approaches. We illustrate its applicability in the context of QTL mapping and GWAS.

Published: October 2023

Background

Autism Spectrum Disorder (ASD) is a neurodevelopmental disability affecting at least 5 million children in South Asia. Majority of these children are without access to evidence-based care. The UK Pre-school Autism Communication Therapy (PACT) is the only intervention to have shown sustained impact on autism symptoms. It was systematically adapted for non-specialist community delivery in South Asia, as the ‘Parent-mediated Autism Social Communication Intervention for non-Specialists (PASS)’ and extended ‘PASS Plus’ interventions. RCTs of both showed feasibility, acceptability and positive effect on parent and child dyadic outcomes.

Methods

The Communication-centred Parent-mediated treatment for Autism Spectrum Disorder in South Asia (COMPASS) trial is now a scale-up two-centre, two-arm single (rater) blinded random allocation parallel group study of the PASS Plus intervention in addition to treatment as usual (TAU) compared to TAU alone, plus health economic evaluation embedded in the India health system. Two hundred forty children (approximately 120 intervention/120 TAU) with ASD aged 2–9 years will be recruited from two tertiary care government hospitals in New Delhi, India. Accredited Social Health Activists will be one of the intervention delivery agents. Families will undertake up to 12 communication sessions over 8 months and will be offered the Plus modules which address coexisting problems. The trial’s primary endpoint is at 9 months from randomisation, with follow-up at 15 months. The primary outcome is autism symptom severity; secondary outcomes include parent–child communication, child adaptation, quality of life and parental wellbeing. Primary analysis will follow intention-to-treat principles using linear mixed model regressions with group allocation and repeated measures as random effects. The cost-effectiveness analysis will use a societal perspective over the 15-month period of intervention and follow-up.

Discussion

If clinically and cost-effective, this programme will fill an important gap of scalable interventions delivered by non-specialist health workers within the current care pathways for autistic children and their families in low-resource contexts. The programme has been implemented through the COVID-19 pandemic when restrictions were in place; intervention delivery and evaluation processes have been adapted to address these conditions.

Published: October 2023

Background

Aedes albopictus and Aedes aegypti are known for their potential as vectors of dengue (DENV) and chikungunya (CHIKV) viruses. However, entomological surveys are mostly carried out during epidemics. In Gabon where outbreaks of both viruses have occurred, there is no vector control program targeting these arboviruses. Therefore, we assessed the presence of Aedes species along a rural–urban gradient in Lambaréné (Gabon) and its surroundings and determined ecological factors associated to their presence.

Methods

An entomological survey was conducted in Lambaréné and its surrounding rural areas. Mosquitoes were collected with aspirators around human dwellings, and ecological and environmental data were collected from each study area. Morphological identification keys were used to identify Aedes species. RNA was extracted from pools of female mosquitoes and amplified by RT-qPCR to detect the presence of DENV and CHIKV.

Results

Overall, the most common vector collected was Aedes albopictus (97%, 4236/4367 specimens), followed by Aedes aegypti (3%, 131/4367). Albopictus vectors was more abundant in the rural area (Wilcoxon signed-rank test, Z = 627, P = 0.043) than in the urban area. In the urban area, a higher number of mosquitoes (45%) were recorded in the economic zone (zone 3) than in the historical and administrative zones (zone 1 and 2). In the rural area, the proportions of species numbers were significantly higher along the south rural transect (92%) compared to the north rural transect (Wilcoxon signed-rank test, Z = 43, P ˂ 0.016). We also noted a high abundance of vectors in environments characterized by monocultures of Hevea brasiliensis (Hevea) and Manihot esculenta (cassava) (Kruskal–Wallis H-test, H = 25.7, df = 2, P < 0.001). Finally, no mosquito pools were positive for either DENV or CHIKV.

Conclusion

Aedes albopictus was the dominant vector across the study sites due to its high invasiveness capacity. This presence re-affirms the potential for local transmission of both DENV and CHIKV, as indicated previously by serological surveys conducted in our study area, even though no transmission was detected during the current study. These findings underscore the need for regular arbovirus surveillance in the study region, with the aim of supporting vector control efforts in the event of outbreaks.

Published: October 2023

Background

Anterior cruciate ligament (ACL) injuries are among the most common injuries in the National Basketball Association (NBA), and it is important to investigate the actual nature of the injury because it can impair a player’s performance after returning to the game. Although the moment of injury has been investigated, the details of the movements and circumstances leading to injury in basketball games are unknown. This study aimed to clarify the actions leading to ACL injuries and to investigate their characteristics, based on YouTube video analyses of the NBA players.

Methods

Players with ACL injuries in the NBA were identified through web-based research over 10 seasons (2011/2012–2021/2022, through October 2021), with 29 recorded videos of ACL injuries in the NBA. Actions were categorized based on basketball-specific gestures, and determined whether the player was in contact with an opponent or not and, if so, the location of the contact was analyzed focusing on two time points: at the injury frame (IF) and one step before the injury frame (IF-1). The “injury leg” timing was counted for each of the first and second steps after ball possession.

Results

The majority (68.2%) of ACL injury occurred during the 2 steps phase (only two steps can proceed after ball retention in basketball, so we defined them as two steps) in the offense action, and most notably during the first step (80.0%). 73.3% of players who were injured during the 2 steps phase got contact to an area other than the knee (Indirect contact) at the IF-1, with 81.8% of contact being located in the upper body contralateral to the respective knee injury. The probability of players with ACL injuries during the 2 steps at the IF-1 who got Indirect contact was statistically significantly greater than those who got no contact with other players (p = 0.042).

Conclusions

We argue that including pre-injury play and contact falls into the novelty category. Through YouTube-based video analyses, this study revealed that ACL injuries tend to be characterized by specific types of actions, the timing of contact, and the location of contact in NBA players.

Published: October 2023

Objective

To investigate the factors influencing the degree of disability in patients with neuromyelitis optica spectrum disorder (NMOSD) and provide evidence for disease monitoring and clinical intervention.

Methods

Eighty-four patients with NMOSD at Xuanwu Hospital Capital Medical University were enrolled in this retrospective study. Before treatment, blood was collected from all patients, and their expanded disability status scores were assessed.

Results

Of the 84 patients assessed, 66 (78.57%) had an expanded disability status scale score < 7, and 18 (21.43%) had scores ≥ 7. The univariate analysis showed that the total bilirubin (TBil), cerebrospinal fluid albumin (CSF ALB), cerebrospinal fluid immunoglobulin G (CSF IgG), QALB, and QIgG levels in the group with scores ≥ 7 were significantly different from those with scores < 7 (P < 0.05). In addition, Spearman’s correlation analysis showed a significant correlation between ALB and expanded disability status scores in patients with NMOSD (P < 0.05), and the multivariate logistic regression analysis showed that TBil was an independent factor influencing the degree of disability in patients with NMOSD (P < 0.05). The receiver operating characteristic curve was constructed using TBil values; the area under the curve of TBil was 0.729 (P < 0.01), and the best cut-off value was 11.015 g/L. Its sensitivity in predicting the severity of disability in NMOSD patients was 51.5% while its specificity was 88.9%.

Conclusion

TBil is an independent factor that influences the severity of disability in patients with NMOSD. In addition, ALB is closely related to NMOSD severity, and some factors associated with the BBB are significantly increased in severely disabled NMOSD patients.

Authors: Yang Chun-Lan , Huang Jia-Peng , Tan Ying-chao , Wang Ting-ting , Zhang Han , Qu Yun
Published: October 2023

Background

Botulinum toxin (BoNT) injection is an important adjunctive method to treat sialorrhea. The purpose of this systematic review was to analyze the effect and safety of BoNT injections in the intervention of sialorrhea with Parkinson’s disease (PD).

Methods

We searched PubMed, Web Of Science (WOS), Scopus, Cochrane CENTRAL, and Embase from inception until April 2022. Randomized controlled trials or randomized crossover trials comparing BoNT with placebo in sialorrhea with PD were eligible. PRISMA guidelines were used to carry out the meta-analysis. The Drooling Severity Frequency Scale (DSFS) score and the number of adverse events (AEs) were the primary and secondary outcomes, respectively. Standardized mean differences (SMDs) and risk differences (RDs) are used to express continuous and categorical outcomes, respectively. Heterogeneity among these studies was evaluated using I2 tests. We used the GRADE tool to assess the certainty of evidence (COE).

Results

Eight articles involving 259 patients compared BoNT injections with a placebo for PD with sialorrhea. This meta-analysis showed a significant reduction in DSFS scores between BoNT injections and placebo (SMD=-0.98; 95% CI, -1.27 to 0.70, p<0.001; COE: high). This meta-analysis showed a significant difference in AEs between BoNT injections and placebo (RD=0.15; 95% CI, 0.05 to 0.24, p=0.002; COE: low).

Conclusions

The pooled results suggest that BoNT injections have some effect on DSFS scores with sialorrhea caused by PD. There are also mild adverse events, which generally recover within a week or so. The results indicate that BoNT injection is one of the treatments for sialorrhea caused by PD, but we need to pay attention to adverse events. In addition, the follow-up time was extended to observe oral hygiene, ulceration or dental caries, and digestive function.

Our review protocol was registered on PROSPERO (42021288334).
Dispersal of juvenile Barrow’s goldeneyes (Bucephala islandica) mirrors that of breeding adults
Authors: Forstner T. M. , Boyd W. S. , Esler D. , Green D. J.
Published: October 2023

Barrow’s goldeneyes across western North America have been shown to have a high degree of subpopulation independence using several data types. However, evidence for structured populations based on mitochondrial DNA, band recoveries, and tracking of adults is discordant with evidence from autosomal DNA. We used satellite tracking data from both juveniles and adults marked on natal and breeding grounds, respectively, in British Columbia, Canada to evaluate the hypothesis that male-biased juvenile dispersal maintains genetic panmixia of Pacific Barrow’s goldeneyes otherwise structured by migratory movements and high winter and breeding site fidelity of adults. We found that juvenile males traveled to overwintering sites located within the range of the overwintering sites of juvenile females, adult males, and adult females. Juvenile males migrated at the same time, travelled the same distance when moving between natal and overwintering sites, and had the same winter dispersion as juvenile females. Although juveniles did not travel with attendant females, all juveniles overwintered within the wintering range of adults. We tracked some juveniles into the following spring/summer and even second winter. Prospecting juveniles of both sexes travelled from their wintering grounds to potential breeding sites in the proximity of Riske Creek and within the bounds of the breeding locations used by adults. Juveniles tracked for more than a year also showed relatively high winter site fidelity. Because Barrow’s goldeneyes pair on wintering grounds, our tracking data are not consistent with the hypothesis that male-biased juvenile dispersal explains the genetic structure in the mitochondrial DNA and panmixia in the autosomal DNA of Barrow’s goldeneye. We suggest that uncommon or episodic dispersal of males might be enough to homogenize autosomal DNA but is unlikely to influence demographic population structure relevant to contemporary population management.
Validity of serum resistin level and Il-6 as prognostic biomarkers of decompensated liver cirrhosis in chronic hepatitis C virus patients
Authors: El-Shayeb Ayman F. , Degheidy Akram A. , El-Mallah Sawsan , Farid John , Abbasy Amany N.
Published: October 2023

Background

Decompensated liver cirrhosis (DLC) is now known as a chronic inflammatory process, evidenced by elevated levels of circulatory pro-inflammatory cytokines and chemokines which in turn lead to the development of more hepatic decompensation and multi-organ failure. Resistin has a pro-inflammatory effect through the production of several cytokines (e.g., IL-1, IL-6, IL-12, and TNF-α) and cell adhesion molecules. Interleukin-6 (IL-6) is a proinflammatory cytokine playing a crucial role in acute phase responses and in regulating immune reactions through activation and differentiation of T and B lymphocytes. The current study aimed to evaluate the value of serum resistin and IL-6 as biomarkers of DLC and their role as prognostic markers of complications in these patients.

Results

This study was conducted on 90 patients divided into three groups: group I—30 patients with compensated cirrhosis (CLC); group II—40 patients with DLC; and group III consisted of 20 healthy controls. Serum resistin and IL-6 levels were statistically significantly higher in patients with DLC compared to patients with CLC at baseline. A cut-off value of > 302 pg/ml for serum resistin was found to discriminate between CLC and DLC with a specificity of 73.33% and sensitivity of 92.50% and a cut-off level of > 31 pg/mL for IL-6 differentiated between the two groups with a sensitivity of 85.0% and specificity of 76.67%. Patients with DLC were followed up for 3 months, 10 patients (25%) passed away, and 19 patients out of the remaining 30 (63.3%) patients developed complications including acute kidney injury, spontaneous bacterial peritonitis, variceal hemorrhage, encephalopathy, and hepatocellular carcinoma. Serum resistin and IL-6 were found to be significantly higher at baseline in those patients who developed complications or mortality after the follow-up period. In addition, there were positive correlations between IL-6 and resistin and MELD-NA and CRP.

Conclusion

Serum resistin and IL-6 could be used as sensitive diagnostic and prognostic biomarkers of decompensated cirrhotic patients.
Does newborn hearing screening cause anxiety among mothers? A cross-sectional study from a tertiary hospital in Malaysia
Authors: Mazlan Rafidah , Abdul Razak Nur Farahain
Published: October 2023

Background

The universal newborn hearing screening (UNHS) has effectively allowed babies with hearing loss to be detected early. However, findings from previous studies indicate that this procedure may adversely induce anxiety among mothers. Therefore, this study aimed to investigate anxiety among mothers whose babies received a hearing screening at a tertiary hospital in Malaysia. A cross-sectional study was conducted on 105 mothers from a tertiary hospital in Kuala Lumpur, Malaysia. Two questionnaires, the Infant Health Concern Scale (IHCS) and State-Trait Anxiety Inventory (STAI), were used to measure the mothers’ worry level on a 4-point Likert scale. Mothers were required to complete the questionnaires twice, before and 4 weeks after discharge, regardless of the hearing screening results.

Results

The STAI scores obtained from mothers whose babies failed the initial screening were significantly higher than mothers whose babies passed. During the initial screening, all mothers rated hearing as the sixth health aspect causing anxiety using the IHCS. However, the ranking fell to 15th place after the second screening. Similarly, mothers whose babies had false positive results also exhibited significantly higher STAI scores and a dropped hearing ranking during rescreening than the initial screening. In addition, mother’s anxiety was not significantly correlated with their education level, family income, or number of births.

Conclusion

Mothers who participated in this study experienced anxiety regardless of their babies hearing screening results. Therefore, the UNHS program must be reviewed to identify appropriate strategies to minimize this negative emotion among mothers.

Computational Advancements in Cancer Combination Therapy Prediction
Authors: Flanary Victoria L. , Fisher Jennifer L. , Wilk Elizabeth J. , Howton Timothy C. , Lasseigne Brittany N.
Published: October 2023

Given the high attrition rate of de novo drug discovery and limited efficacy of single-agent therapies in cancer treatment, combination therapy prediction through in silico drug repurposing has risen as a time- and cost-effective alternative for identifying novel and potentially efficacious therapies for cancer. The purpose of this review is to provide an introduction to computational methods for cancer combination therapy prediction and to summarize recent studies that implement each of these methods. A systematic search of the PubMed database was performed, focusing on studies published within the past 10 years. Our search included reviews and articles of ongoing and retrospective studies. We prioritized articles with findings that suggest considerations for improving combination therapy prediction methods over providing a meta-analysis of all currently available cancer combination therapy prediction methods. Computational methods used for drug combination therapy prediction in cancer research include networks, regression-based machine learning, classifier machine learning models, and deep learning approaches. Each method class has its own advantages and disadvantages, so careful consideration is needed to determine the most suitable class when designing a combination therapy prediction method. Future directions to improve current combination therapy prediction technology include incorporation of disease pathobiology, drug characteristics, patient multiomics data, and drug-drug interactions to determine maximally efficacious and tolerable drug regimens for cancer. As computational methods improve in their capability to integrate patient, drug, and disease data, more comprehensive models can be developed to more accurately predict safe and efficacious combination drug therapies for cancer and other complex diseases.
Evaluation of Hydrophobic Attraction between Polystyrene Layer and Silanated Silica Surface by Atomic Force Microscopy
Authors: Okuda Yuta , Imamura Koreyoshi , Ishida Naoyuki
Published: October 2023

In this study, hydrophobic surfaces were prepared by depositing polystyrene (PS) on a glass substrate using three different methods to measure the interaction forces against a hydrophobized particle by atomic force microscopy. We found that smooth surfaces prepared by spin coating and living radical polymerization generated hydrophobic attraction, whereas uneven surfaces obtained by free radical polymerization produced only steric repulsion, even though they had sufficient hydrophobicity. Based on these results, the origin of the hydrophobic attraction was suggested.
