Abstract
Introduction
The diagnosis and care of children and adolescents with neurodevelopmental disorders presents a public health crisis in China. Attention deficit hyperactivity disorder (ADHD) is one of the most frequent conditions. Many Chinese children and adolescents with ADHD are underdiagnosed and undertreated. This study aimed to evaluate the awareness and attitude parents have about ADHD, and investigated potential factors influencing ADHD medical visit status among school-aged children in Shanghai.

Methods
A random cluster sampling method was used, and four primary schools in Shanghai were selected. One class was randomly selected from each grade, including students and their parents. Parents completed the Swanson, Nolan, and Pelham Version IV Questionnaire (SNAP-IV) parent form and questionnaire concerning ADHD awareness, knowledge, attitude and status of ADHD medical visit. Descriptive analysis was conducted on the overall results and logistic regression analysis was performed to explore the influencing factors of ADHD medical visit.

Results
We received 617 valid questionnaires. There were 313 boys (50.7%) and 304 girls (49.2%), with a median age of 8 years old (p25 = 7, p75 = 9). 42.4% parents believed they had some knowledge about ADHD, and 73.5% of them thought ADHD was a neurologically based disorder or neurological condition by nature. Parental ADHD information came from the following sources: Internet/TV (n = 458, 74.2%), families/friends (n = 267, 43.2%), print publication (n = 208, 33.7%), psychiatrists/pediatricians (n = 192, 31.1%), schools/teachers (n = 186, 30.1%) and other ADHD patients (n = 48, 7.7%). When children had ADHD-like behaviors, most parents (61.5%) educated children to behave themselves, 59.1% parents tried to get help from psychiatrists/pediatricians, 55.5% of them would ask psychologist for help. In terms of the ADHD prevalence, the SNAP-IV positive screen rate was 4.3% (n = 27). Only 33.3% (9/27) of parents went to the hospital for consultation and treatment. Multivariate logistic regression model showed that parental knowledge about ADHD (OR = 13.67, 95%CI: 1.72, 144.39, P = 0.01) was significantly correlated with the medical visit. Parents with sufficient knowledge of ADHD tend to visit hospital for help when they thought their children had ADHD related symptoms.

Conclusions
The majority of parents accepted ADHD as a neurodevelopmental disorder by nature, but some parents still had certain misunderstandings about ADHD. The main source of information for parents to obtain information about ADHD was through the TV/Internet. Parents’ perceptions and knowledge were key to whether children received appropriate treatment for their ADHD. However, medical visits to address ADHD among school-aged children were still lower than expected. Government and healthcare institutes should work to improve ADHD public awareness and to help patients and their families gain access to mental health resources.

Abstract
Background
Lung cancer remains one of the most prevalent cancer types worldwide, with a high mortality rate. Upregulation of programmed cell death protein 1 (PD-1) and its ligand (PD-L1) may represent a key mechanism for evading immune surveillance. Immune checkpoint blockade (ICB) antibodies against PD-1 or PD-L1 are therefore widely used to treat patients with lung cancer. However, the mechanisms by which lung cancer and neutrophils in the microenvironment sustain PD-L1 expression and impart stronger inhibition of CD8+ T cell function remain unclear.

Methods
We investigated the role and underlying mechanism by which PD-L1+ lung cancer and PD-L1+ neutrophils impede the function of CD8+ T cells through magnetic bead cell sorting, quantitative real-time polymerase chain reaction (RT-PCR), western blotting, enzyme-linked immunosorbent assays, confocal immunofluorescence, gene silencing, flow cytometry, etc. In vivo efficacy and safety studies were conducted using (Non-obeseDiabetes/severe combined immune deficiency) SCID/NOD mice. Additionally, we collected clinical and prognostic data from 208 patients who underwent curative lung cancer resection between 2017 and 2018.

Results
We demonstrated that C-X-C motif chemokine ligand 5 (CXCL5) is markedly overexpressed in lung cancer cells and is positively correlated with a poor prognosis in patients with lung cancer. Mechanistically, CXCL5 activates the phosphorylation of the Paxillin/AKT signaling cascade, leading to upregulation of PD-L1 expression and the formation of a positive feedback loop. Moreover, CXCL5 attracts neutrophils, compromising CD8+ T cell-dependent antitumor immunity. These PD-L1+ neutrophils aggravate CD8+ T cell exhaustion following lung cancer domestication. Combined treatment with anti-CXCL5 and anti-PD-L1 antibodies significantly inhibits tumor growth in vivo.

Conclusions
Our findings collectively demonstrate that CXCL5 promotes immune escape through PD-L1 upregulation in lung cancer and neutrophils chemotaxis through autocrine and paracrine mechanisms. CXCL5 may serve as a potential therapeutic target in synergy with ICBs in lung cancer immunotherapy.
External validation of Standardized KELIM and platinum-resistant recurrence scores in patients with advanced epithelial ovarian cancer
Authors: Oufkir Nina , Rouzier Roman , Paoletti Xavier , Bonneau Claire 
Published: July 2024

Abstract
Background
Neoadjuvant chemotherapy followed by interval debulking surgery is currently a common treatment option for advanced epithelial ovarian cancer (EOC). The Standardized CA-125 ELIMination rate constant K (Std KELIM) and the Platinum Resistant Recurrence (PtRR) Score have been proposed as markers of tumor chemosensitivity. The aim of our study was to validate these tools for predicting platinum sensitivity in a real-world population of patients with advanced EOC treated with neoadjuvant chemotherapy.

Experimental design
All patients with advanced EOC treated with neoadjuvant chemotherapy at the Institut Curie between 2000 and 2015 were included. The Std KELIM was calculated with the CA-125 concentrations during the first 100 days of chemotherapy. The predictive value of Std KELIM and PtRR scores for the risk of subsequent PtRR was assessed using receiver operating characteristic (ROC) curve analysis, logistic regression and calibration curve. Kaplan–Meier survival analysis was performed for the treatment-free interval from platinum (TFIp) therapy and overall survival (OS).

Results
Std KELIM data were available for 149 patients. The AUC was 0.67 for PtRR. A low Std KELIM was significantly associated with PtRR (OR = 0.19 (95% CI [0.06, 0.53], p = 0.002)) according to the univariate analysis. The calibration curve of the PtRR showed a slight but significant underestimation (p = 0.02) of the probability of platinum resistance. Favorable Std KELIM (≥ 1) alone and combined with the completeness of surgery were associated with significantly better survival in terms of TFIp and OS.

Conclusions
Std KELIM is an early prognostic marker of chemosensitivity in a real-life setting complementary to surgical status. It could help the clinician in the early management of patients by identifying those with a worse prognosis.

Published: July 2024

Abstract
Background and aim
Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is an autosomal dominant syndrome characterized by fundic gland polyps (FGP) as well as an increased risk of gastric cancer. The syndrome has been recognized as a clinical entity for less than a decade. A clinical suspicion may be complex and can vary from incidental findings of FGPs at gastroscopy to obstructive symptoms with dyspepsia and vomiting. The diagnosis is established by genetic detection of a pathogenic variant in the promotor 1B region of the APC gene. As of yet there are no established clinical criteria for the diagnosis. To increase knowledge of the condition and to discuss possible genetic testing and surveillance strategies, we performed a systematic review of all reported patients with GAPPS.

Methods
This review was organized according to PRISMA guidelines. The search, which was conducted on September 7th, 2023, was applied to MEDLINE and restricted to only humans and papers in the English language. Only the studies on patients/families with GAPPS verified by identification of a pathogenic variant in the APC promoter 1B were included.

Results
Twelve publications with a total of 113 patients were identified. In all instances the diagnosis was genetically verified with reports of four different variants within the APC promotor 1B region. Eighty-eight patients (90.1%) had gastric polyps, of these seven patients had low-grade dysplasia and five patients had both low- and high-grade dysplasia. Thirty-seven patients (45.7%) underwent gastrectomy. There were no reports of duodenal polyps (0%). Gastric cancer was found in 31 patients (30.1%) with a median age of 48 years (range 19–75). Twenty-six patients died (23.2%) of which 19 had developed gastric cancer (73.1%). One patient was diagnosed with metastatic colorectal cancer (2.2%) and died at 73 years of age. Nineteen patients had colorectal manifestations with < 20 polyps (41.3%).

Conclusion
Patients with a pathogenic variant in the APC promoter 1B region have an increased risk of gastric polyposis and early-onset gastric cancer. However, there is considerable variation in clinical expression and penetrance, which makes decisions on surveillance and the timing of prophylactic gastrectomy challenging.
Effects of starting one lung ventilation and applying individualized PEEP right after patients are placed in lateral decubitus position on intraoperative oxygenation for patients undergoing thoracoscopic pulmonary lobectomy: study protocol for a randomized controlled trial
Authors: Wang Qing-Yuan , Zhou Yang , Wang Meng-Rui , Jiao You-You 
Published: July 2024

Abstract
Background
For patients receiving one lung ventilation in thoracic surgery, numerous studies have proved the superiority of lung protective ventilation of low tidal volume combined with recruitment maneuvers (RM) and individualized PEEP. However, RM may lead to overinflation which aggravates lung injury and intrapulmonary shunt. According to CT results, atelectasis usually forms in gravity dependent lung regions, regardless of body position. So, during anesthesia induction in supine position, atelectasis usually forms in the dorsal parts of lungs, however, when patients are turned into lateral decubitus position, collapsed lung tissue in the dorsal parts would reexpand, while atelectasis would slowly reappear in the lower flank of the lung. We hypothesize that applying sufficient PEEP without RM before the formation of atelectasis in the lower flank of the lung may beas effective to prevent atelectasis and thus improve oxygenation as applying PEEP with RM.

Methods
A total of 84 patients scheduled for elective pulmonary lobe resection necessitating one lung ventilation will be recruited and randomized totwo parallel groups. For all patients, one lung ventilation is initiated the right after patients are turned into lateral decubitus position. For patients in the study group, individualized PEEP titration is started the moment one lung ventilation is started, while patients in the control group will receive a recruitment maneuver followed by individualized PEEP titration after initiation of one lung ventilation. The primary endpoint will be oxygenation index measured at T4. Secondary endpoints will include intrapulmonary shunt, respiratory mechanics, PPCs, and hemodynamic indicators.

Discussion
Numerous previous studies compared the effects of individualized PEEP applied alone with that applied in combination with RM on oxygenation index, PPCs, intrapulmonary shunt and respiratory mechanics after atelectasis was formed in patients receiving one lung ventilation during thoracoscopic surgery. In this study, we will apply individualized PEEP before the formation of atelectasis while not performing RM in patients allocated to the study group, and then we’re going to observe its effects on the aspects mentioned above. The results of this trial will provide a ventilation strategy that may be conductive to improving intraoperative oxygenation and avoiding the detrimental effects of RM for patients receiving one lung ventilation.

The relationship between loneliness and blood glucose: a cross-sectional survey among Japanese
Authors: Tran Quyen An , Nakamura Sho , Watanabe Kaname , Chei Choy-Lye , Narimatsu Hiroto 
Published: July 2024

AbstractRecently, researchers have uncovered a correlation between loneliness and both the development and management of diabetes. Nevertheless, previous studies employing an unvalidated loneliness questionnaire impair result accuracy. Furthermore, this aspect has not been researched in the Japanese population. Therefore, this cross-sectional study analyzed data from the Kanagawa prospective “ME-BYO” Cohort Study (ME-BYO cohort) to investigate the correlation between loneliness, as measured by 20 items on the UCLA Loneliness Scale, and blood glucose levels. A total of 666 participants were included in the analysis, with a mean age of 54.1 years and a mean BMI of 23 kg/m2. Half of the participants had obtained an education level beyond high school. The mean household income and physical activity level were reported as 6.83 million Japanese yen and 12.3 METs-h/day, respectively. Model 1 of the linear regression analysis determined that there was no significant association between the loneliness scale and HbA1c (p = 0.512). After adjusting for age, gender, BMI (model 2), sitting time, physical activity level (model 3), housemates, household income, and final education (model 4), and controlling for social support, quality of life, and depression (model 5), the results showed no significant association, with a p-value of 0.823, 0.791, 0.792, and 0.816, respectively. Thus, the study found no link between loneliness and HbA1c in the high SES population. This finding contradicts previous results and may be attributed to the impact of population characteristics, SES status, or genetic backgrounds.

Abstract
Background
Females represent approximately 70% of the Alzheimer’s disease (AD) cases and the literature has proposed a connection between the decreased estrogen levels during menopause and an increased AD risk. Previous investigations have predominantly focused on assessing how hormone therapy (HT) affects the likelihood of AD development and cognitive deterioration. However, as the research framework has shifted toward a biomarker-defined AD and alterations in specific biomarkers could take place years before cognitive decline becomes discernible, it is crucial to examine how HT influences AD biomarkers. The main goal of this study was to evaluate the impact of HT on AD biomarker-informed pathophysiology in both cognitively unimpaired (CU) and cognitively impaired (CI) post-menopausal females across the aging and AD spectrum.

Methods
This cross-sectional study included post-menopausal females without HT history (HT-) and with HT (HT+) at the time of PET imaging assessment from two cohorts: the Translational Biomarkers in Aging and Dementia (TRIAD) cohort, and the Alzheimer’s Disease Neuroimaging Initiative (ADNI). Participants underwent magnetic resonance imaging (MRI), positron emission tomography (PET) and biofluid collection. Voxel-based t-tests were performed to assess the differences in amyloid-β (Aβ) and tau neurofibrillary tangles (NFTs) loads between HT- and HT + females. Linear regression models with interaction terms were also conducted to examine the interactive effects of HT and Aβ-PET on regional tau-PET.

Results
HT + females demonstrated significantly lower tau-PET standardized uptake value ratio (SUVR) in Braak I-II ROIs (P < 0.05, Hedges’ g = 0.73), Braak III-IV ROIs (P < 0.0001, Hedges’ g = 0.74) and Braak V-VI ROIs (P < 0.0001, Hedges’ g = 0.69) compared to HT- females. HT + females also showed significantly lower CSF p-tau181 (P < 0.001) and plasma p-tau181 (P < 0.0001) concentrations. Additionally, results from multivariate linear regression models indicated that HT interacts with cortical Aβ and is associated with lower regional NFT load.

Conclusions
Overall, findings from this observational study suggest that HT is associated with lower tau neuroimaging and fluid biomarkers in postmenopausal females. Due to the close link between tau and cognition, this study highlights the need for large randomized controlled trials designed to systemically study the influences of HT on AD biomarkers and disease progression.
3D imaging as a method of measuring serotiny
Authors: van Mantgem Carolyn F. 
Published: July 2024

Abstract
Background
Serotiny, or pyriscence, refers to delayed seed dissemination within plants and plays an important role in the population dynamics of species following fire. Accurately understanding the variation in serotiny is crucial to predicting ecosystem responses to changing fire regimes. Three-dimensional (3D) cone surface area is one critical trait that can be used to characterize responses in serotinous species following fire, yet approaches to accurately measure cone surface area are limited. Cone surface area in regards to this paper is the total area of all surfaces of the cone. Past studies have relied on visual estimation to determine the openness of cones or to identify when cones become open. Subjective assessments of cone opening may be insufficient to adequately characterize cone responses to fire. In this study, I demonstrate the effectiveness of 3D modeling using a readily available phone camera and applications (Polycam, Blender) to quantify differences in 3D surface area of cones before and after heating treatments by comparing two serotinous conifer species, Monterey cypress (Hesperocyparis macrocarpa) and bishop pine (Pinus muricata).

Results
Bishop pine had an average cone surface area increase of 175.7% while Monterey cypress had an average cone surface area increase of 43.5%. Paired t-tests showed that cone surface area significantly increased following heating for both species.

Conclusions
Bishop pine showed a much greater cone surface area change relative to Monterey cypress. 3D imaging with the phone application, Polycam, proved to be a successful method of quantifying cone opening, creating a mesh that could be measured with the post-image processing software, Blender. A mesh can be defined as a digital 3D representation of an object made up of connected vertices that create edges and faces. Using a readily available phone camera, one can create an accurate 3D model to measure changes in the surface area of cones before and after fire. Simple methods for quantifying serotiny, such as demonstrated here, allow for improved understanding and predictions of how species respond to fire and other environmental triggers but require further investigation including, but not limited to, comparisons between serotinous species, facultative serotinous species, and non-serotinous species.

Abstract
Background
Successful HIV treatment programs have turned HIV into a chronic condition, but noncommunicable diseases such as hypertension jeopardize this progress. Hypertension control rates among people with HIV (PWH) are low owing to gaps in patient awareness, diagnosis, effective treatment, and management of both conditions at separate clinic visits. Integrated management, such as in our study, InterCARE, can enhance HIV-hypertension integration and blood pressure (BP) control.

Methods
Our pilot study was conducted in two Botswana HIV clinics between October 2021 and November 2022. Based on our formative work, we adopted three main strategies; Health worker training on HTN/cardiovascular disease (CVD) management, adaptation of HIV Electronic Health Record (EHR) for HTN/CVD care, and use of treatment partners to support PWH with hypertension for implementation. We employed the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework to assess implementation effectiveness and outcomes for BP control at baseline, 6 and 12 months. HIV viral load (VL) suppression was also measured to assess impact of integration on HIV care.

Results
We enrolled 290 participants; 35 (12.1%) were lost to follow-up, leaving 255 (87.9%) at 12-months. Median age was 54 years (IQR 46–62), and 77.2% were females. Our interventions significantly improved BP control to < 140/90 mmHg (or < 130/80 mmHg if diagnosis of diabetes or chronic kidney disease), from 137/290 participants, 47.2% at baseline to 206/290 participants, 71.0%, at 12 months (p < 0.001). Among targeted providers, 94.7% received training, with an associated significant increase in counseling on exercise, diet, and medication (all p < 0.001) but EHR use for BP medication prescribing and cardiovascular risk factor evaluation showed no adoption. In the intention-to-treat analysis, HIV VL suppression at 12 months decreased (85.5% vs 93.8%, p = 0.002) due to loss to follow-up but the per protocol analysis showed no difference in VL suppression between baseline and 12 months (97.3% vs 93.3%, p = 0.060).

Conclusion
The InterCARE pilot study demonstrated that low-cost practical support measures involving the integration of HIV and hypertension/CVD management could lead to improvements in BP control. These results support the need for a large implementation and effectiveness trial.
