OBJECTIVE: To develop a diagnostic approach that combines measurements of cellular and serologic autoimmunity.
METHODS: We recruited 71 controls and 101 pediatric patients with PIRD with autoimmunity. Flow cytometry was used to measure CD4+CXCR5+ T cells expressing the chemokine receptors CXCR3 and/or CCR6. IgG and IgA autoantibodies were quantified in 56 patients and 20 controls using a microarray featuring 1616 full-length, conformationally intact protein antigens. The 97.5th percentile in the controls serves as the upper limit of normal for percentages of cTfh cells, CD4+CXCR5+ T cells expressing CXCR3 and/or CCR6, and autoantibody intensity and number.
RESULTS: We found that 27.7% of patients had increased percentages of CD4+CXCR5+PD1+ cTfh cells and 42.5% had increased percentages of CD4+CXCR5+ cells expressing CXCR3 and/or CCR6. Patients had significantly more diverse IgG and IgA autoantibodies than controls and 37.5% had increased numbers of high-titer autoantibodies. Integrating measurements of cTfh cells, CD4+CXCR5+ T cells with CXCR3 and/or CCR6, and numbers of high-titer autoantibodies had 71.4% sensitivity (95% CI: 0.5852 - 0.8158) and 85% specificity (95% CI: 0.6396 - 0.9476) for patients with PIRD compared to controls.
CONCLUSION: By integrating CD4+ T cell phenotyping and total burden of autoantibodies, this approach provides additional tools for the diagnosis of PIRD lacking clinical diagnostic criteria.
DESIGN: An online survey was disseminated through the British Academy of Audiology and ENT UK.
STUDY SAMPLE: A total of 191 hearing healthcare professionals responded to the survey.
RESULTS: Overall, while 63% of the respondents considered themselves to be adequately informed about APD, only 4% viewed themselves as very informed on the topic. Fewer than half of the respondents report screening (31%), diagnosing (14%), or managing (36%) cases of APD. For screening APD, professionals most commonly use auditory processing tests in adults and take case histories in children, whereas routine audiological procedures are the primary method for diagnosing APD in both adults and children. Although modifying the listening environment is a widely recommended management strategy for APD, half of the respondents indicated that a diagnosis of APD has no implications for patient management.
CONCLUSIONS: There is a critical need to promote APD-related training to ensure they can provide appropriate referrals and management.
METHODS: A validated patient self-reporting e-survey was circulated by the COVAD study group to collect data on COVID-19 infection and vaccination in 2022. BIs were defined as COVID-19 occurring ≥14 days after two vaccine doses. We compared BI characteristics and severity among patients with IIMs, patients with other autoimmune rheumatic and non-rheumatic diseases (AIRD, nrAID), and healthy controls (HCs). Multivariable Cox regression models were used to assess the risk factors for BI, severe BI ,and hospitalizations among patients with IIMs.
RESULTS: Among the 9449 included responses, BIs occurred in 1447 respondents (15.3%). The median age was 44 years [interquartile range (IQR) 21], 77.4% were female, and 182 BIs (12.9%) occurred among the 1406 patients with IIMs. Multivariable Cox regression among the data for patients with IIMs showed increasing age to be a protective factor for BIs [hazard ratio (HR) = 0.98, 95% CI = 0.97-0.99], and HCQ and SSZ use were risk factors (HR = 1.81, 95% CI = 1.24-2.64, and HR = 3.79, 95% CI = 1.69-8.42, respectively). Glucocorticoid use was a risk factor for a severe BI (HR = 3.61, 95% CI = 1.09-11.8). Non-white ethnicity (HR = 2.61, 95% CI = 1.03-6.59) was a risk factor for hospitalization. Compared with other groups, patients with IIMs required more supplemental oxygen therapy (IIMs = 6.0% vs AIRDs = 1.8%, nrAIDs = 2.2% and HCs = 0.9%), intensive care unit admission (IIMs = 2.2% vs AIRDs = 0.6%, nrAIDs and HCs = 0%), advanced treatment with antiviral or monoclonal antibodies (IIMs = 34.1% vs AIRDs = 25.8%, nrAIDs = 14.6% and HCs = 12.8%) and had more hospitalization (IIMs = 7.7% vs AIRDs = 4.6%, nrAIDs = 1.1% and HCs = 1.5%).
CONCLUSION: Patients with IIMs are susceptible to severe COVID-19 BIs. Age and immunosuppressive treatments were related to the risk of BIs.
OBJECTIVES: To explore the experiences and preferences of Malaysian patients with advanced cancer.
DESIGN: Qualitative study of semi-structured interviews with thematic analysis.
SETTING/SUBJECTS: Purposive sampling of 19 patients with Stage 4 cancer recruited from inpatient and outpatient settings in National Cancer Institute Malaysia.
RESULTS: Three major themes emerged in the exploration of patients' experiences and care preferences in facing advanced cancer namely: 1) Dealing with poor prognosis 2) Spirituality as a source of strength and 3) Enablers of advance care planning.
CONCLUSION: This study highlighted the preference for healthcare providers to be culturally sensitive during end-of-life care discussion and the need for improved spiritual care for Malaysian patients with advanced cancer. Further studies exploring the role of spiritual and cultural factors in advance care planning among Malaysians would be helpful in guiding these efforts.
OBJECTIVE: Different specialists' perceptions and managements of CRS in Asia-Pacific regions were assessed in an attempt to gauge these practices against EPOS 2020 guidelines.
METHODS: A transregional, cross-sectional survey was conducted to assess otolaryngologists' and allergists' perceptions and managements of CRS with regard to diagnosis, management and adherence to EPOS 2020 guidelines.
RESULTS: Sixteen physicians in Asia-Pacific regions responded to the questionnaire. A total of 71.4% of otolaryngologists preferred to diagnose CRS with a combination of positive nasal symptoms and nasal endoscopy plus sinus CT, whereas 22.2% of allergists took such criterion to diagnose CRS. Compared to allergists, otolaryngologists more often considered the endotype classification (85.8% versus 55.5%). For the preferred first-line treatment, in addition to intranasal corticosteroids recommended by all respondents, 66.7% of allergists preferred antihistamines, whereas 71.4% of otolaryngologists preferred nasal saline irrigation. Regarding the proper timing of surgery, 71.5% of otolaryngologists reported 8-12 weeks of treatment after the initiation of medication, while more than half of the allergists recommended 4-6 weeks of medical treatment.
CONCLUSIONS: This survey shows that variable perceptions and practices for CRS may exist between physicians with different specialties and highlights the need for increased communication and awareness between otolaryngologists and allergists to improve the diagnosis and treatment of CRS.

OBJECTIVE: To collect detailed information about the practical management patterns specific for AR patients and investigate compliance with ARIA in the clinical practice of Asian physicians and elucidate the possible inadequacy in the existing ARIA guidelines.
METHODS: An e-mail with a structured questionnaire was sent to members of the Asia-Pacific Association of Allergy, Asthma and Clinical Immunology. The questionnaire consisted of doctors' characteristics, environment of medical practice, routine clinical practice following ARIA guidelines and patients' adherence to the prescription.
RESULTS: Physicians from 14 countries and regions sent valid questionnaires back, 94.12% of whom were senior doctors with more than 10 years of experience. 88.24% of doctors diagnosed AR depending on the history combined with allergy tests. 82.35% of participants employed the classification criteria by ARIA. 94.12%, 88.24% and 41.8% of respondents recommended intranasal corticosteroids, oral antihistamines and leukotriene receptor antagonists as first-line medications. 5.88% treated perennial AR by intranasal corticosteroids alone. 11.76% of clinicians recommended no allergen immunotherapy (AIT) or biologics and 58.82% of interviewees reported AR patients occasionally or sometimes agreed with the recommendation of AIT.
CONCLUSIONS: There was high compliance with ARIA guidelines in Asian senior physicians' actual notion and practice in the management of AR. New-generation ARIA guidelines are imperative for unmet needs.
MATERIALS AND METHODS: This randomized clinical trial (RCT) recruited a total of 60 patients undergoing HD from the 9 Dey Hospital in Torbat Heydariyeh, Iran, between March and August 2022. These patients were then divided into two groups: the intervention group and the control group. The intervention group received distraction techniques using the Shinecon 4th Gen Virtual Reality Headset, while the control group received routine care services. To assess the level of pain experienced during AVF cannulation, the Visual Analog Scale (VAS) was utilized. The collected data were analyzed using SPSS20. Various statistical tests, including the Chi-square test, Mann-Whitney U test, Multiple linear regression, and independent-samples t-test, were employed for data analysis. Additionally, Cohen's d was used to determine the effect size of the intervention.
RESULTS: The analysis of the data revealed a statistically significant difference in the mean (SD) pain scores between the control group (7.6 ± 0.8) and the intervention group (5.1 ± 0.9) (p
AIM OF REVIEW: The review encapsulates the transformative trajectory of green CDs as future anticancer nanomedicine, poised to redefine the strategies employed in the ongoing fight against cancer.
KEY SCIENTIFIC CONCEPTS OF REVIEW: The versatility of CDs was rooted in their various synthesis approaches and sustainable strategies, enabling their adaptability for diverse therapeutic uses. In vitro studies had showcased CDs' selective cytotoxicity against cancer cells while sparing healthy counterparts, forming the basis for targeted therapeutic potential. This selectivity had been attributed to the reactive oxygen species (ROS) generation, which opened avenues for targeted interventions. The role of CDs in combination therapies, synergizing with chemotherapy, radiotherapy, and targeted approaches was then investigated to heighten their anticancer efficacy. Notably, in vivo studies highlight CDs' remarkable biocompatibility and minimal side effects, endorsing their translational promise. Integration with conventional cancer treatments such as chemotherapy, radiotherapy, and immunotherapy amplified the versatility and effectiveness of CDs. The exploration of CDs' applications in photo-induced treatments further solidified their significance, positioning them as photosensitizers (PS) in photodynamic therapy (PDT) and photothermal agents (PA) in photothermal therapy (PTT). In PDT, CDs triggered the generation of ROS upon light exposure, facilitating cancer cell elimination, while in PTT, they induced localized hyperthermia within cancer cells, enhancing therapeutic outcomes. In vitro and in vivo investigations validated CDs' efficacy in PDT and PTT, affirming their potential for integration into combination therapies. Looking ahead, the future of CDs in anticancer treatment encompasses bioavailability, biocompatibility, synergistic treatments, tumor targeting, artificial intelligence (AI) and robotics integration, personalized medicine, and clinical translation. This transformative odyssey of CDs as future anticancer agents is poised to redefine the paradigm of cancer treatment strategies.
MATERIALS AND METHODS: Using a thematic review framework, a systematic literature search was conducted in two electronic databases (Scopus and WoS) using established criteria. Thematic analysis was done using ATLAS.ti 23 to identify prominent themes, patterns and trends.
RESULTS: A total of 180 documents were found. Twenty-five articles met the inclusion criteria. A thematic review of these 25 articles identified 13 initial codes, which were been clustered into four themes: detection and evaluation; intervention; toy/game category; and design characteristics. The word "Cognitive" appears most frequently in documents according to word cloud.
CONCLUSIONS: Therapeutic toys and games are used to detect and as an intervention for AD. Most of the current studies focused on specific cognitive functions. More research is needed about play therapy for neuropsychiatric symptoms. This thematic review also proposed a conceptual framework for designing toys and games tailored to the needs of the elderly with AD, offering valuable insights to future researchers focusing on this domain.
METHODS: ZnO NPs were prepared by co-precipitation method, and their anti-biofilm and antibacterial activities alone or combined with four types of broad-spectrum antibacterial (Norfloxacin, Colistin, Doxycycline, and Ampicillin) were evaluated against E. coli and S. aureus bacterial strains. Finally, the cytotoxicity and the hemolytic activity were evaluated.
RESULTS: ZnO NPs were prepared, and results showed that their size was around 10 nm with a spherical shape and a zeta potential of -21.9. In addition, ZnO NPs were found to have a strong antibacterial effect against Gram-positive and Gram-negative microorganisms, with a minimum inhibitory concentration (MIC) of 62.5 and 125 μg/mL, respectively. Additionally, they could eradicate biofilmforming microorganisms at a concentration of 125 μg/m. ZnO NPs were found to be non-toxic to erythrocyte cells. Still, some toxicity was observed for Vero cells at effective concentration ranges needed to inhibit bacterial growth and eradicate biofilm-forming organisms. When combined with different antibacterial, ZnO NP demonstrated synergistic and additive effects with colistin, and the MIC and MBEC of the combination decreased significantly to 0.976 μg/mL against planktonic and biofilm strains of MDR Gram-positive bacteria, resulting in significantly reduced toxicity.
CONCLUSION: The findings of this study encourage the development of alternative therapies with high efficacy and low toxicity. ZnO nanoparticles have demonstrated promising results in overcoming multi-drug resistant bacteria and biofilms, and their combination with colistin has shown a significant reduction in toxicity. Further studies are needed to investigate the potential of ZnO nanoparticles as a viable alternative to conventional antibiotics.
CONTENT: The search involved various databases such as; Science Direct, PubMed, SAGE, Springer Link, EBCOHOST, MEDLINE, CINAHL, Cochrane library, Web of Science and Wiley Online Library. It was limited to full text research articles that reported the use of non-viable method in assessing bioaerosol, written in English Language, full text publications and published from year 2015-2022.
SUMMARY AND OUTLOOK: A total of 15 articles met the inclusion criteria and was included in this review. The use of next-generation sequencing, which is more commonly referred to as high-throughput sequencing (HTS) or molecular methods in microbial studies is based on the detection of genetic material of organisms present in a given sample. Applying these methods to different environments permitted the identification of the microorganisms present, and a better comprehension of the environmental impacts and ecological roles of microbial communities. Based on the reviewed articles, there is evidence that dust samples harbour a high diversity of human-associated bacteria and fungi. Molecular methods such as next generation sequencing are reliable tools for identifying and tracking the bacterial and fungal diversity in dust samples using 18S metagenomics approach.
METHODS: It was a retrospective cohort study of prospectively submitted data by 44 Malaysian NICUs participating in the Malaysian National Neonatal Registry. All VLBW neonates of gestation <32 wk born in 2015-2020 and survived to discharge were included.
RESULTS: Of 11768 survivors, 90.5% (n = 10436) had ROP screening; 16.1% (1685/10436) had ROP. ROP was significantly more common in neonates <28 wk gestation (extremely preterm, EPT) than ≥28 wk gestation (37.7% vs. 9.7%; p <0.001), and more common in those with birthweight <1000 g (extremely low birthweight, ELBW) than ≥1000 g (32.9% vs. 9.1%; p <0.001). Multiple logistic regression analysis showed that the significant independent factors associated with increased risk of ROP were ELBW, EPT, Indian ethnic group, vaginal delivery, mechanical ventilation >5 d, high frequency ventilation, total parenteral nutrition, late-onset sepsis, bronchopulmonary dysplasia, and intraventricular hemorrhage. Receiving oxygen therapy at birth was associated with significantly lower risk of ROP.
CONCLUSIONS: The incidence and severity of ROP increased with decreasing gestation and birthweight. Prolonged duration of oxygen therapy, infection, invasive respiratory support, and conditions commonly causing fluctuations of oxygenation were significant factors associated with increased risk of ROP. Receiving oxygen at birth did not increase risk.
METHODS: RPE, heart rate (HR), and oxygen uptake (V˙O2) data were retrospectively extracted from 3 lab-based crossover studies, with a pooled sample size of 45 adolescents, performing either cycling-based or running-based HIIE sessions. Within-participant correlations were calculated for RPE-HR and RPE-V˙O2, and receiver operator characteristic curve analysis was used to establish RPE cut points.
RESULTS: The results showed that RPE-HR demonstrated acceptable criterion validity (r = .53-.74, P < .01), while RPE-V˙O2 had poor validity (r = .40-.48, P < .01), except for HIIE at 100% peak power (r = .59, P < .01). RPE cut points of 4 and 5 were established in corresponding to HR/V˙O2 based thresholds.
CONCLUSION: RPE has some utility in evaluating intensity during lab-based running or cycling HIIE in adolescents. Future studies should expand the validation and calibration of RPE for prescribing and monitoring HIIE in children and adolescents in field-based contexts.
