Abstract
Objective
The primary purpose of this study was to assess the prevalence and socio-behavioral determinants of ever-use of dental care services among adolescents aged 10–18 years, living with HIV, on Antiretroviral treatment (ART), and attending selected HIV clinics in Kampala, Uganda.

Methods
A cross-sectional study was carried out between March and September 2020. The study conveniently recruited 154 adolescents between 10 and 18 years old from 4 specific HIV clinics in Kampala. Andersen’s behavioral model guided the selection of variables, with the ever-use of dental care services as the outcome and predisposing, enabling, need-related factors and personal dental health practices as exposure variables. Data were analyzed using Fischer’s exact test for cross-tabulation and modified Poisson regression for multivariate analysis.

Results
The prevalence of ever-use of dental care services was 12.3%. The adolescents aged 14–18 had higher odds of using dental care services (Prevalence ratio (PR) of 3.35 than those aged 10–13 years. Fear of the spread of HIV was negatively associated with ever-use of dental care services (PR of 0.06). Participants who were afraid of going to the dentist had higher odds of using dental care services (PR of 2.98) than those not afraid. Failure to receive dental treatment because it was not part of the medical appointment had a positive association with the ever-use of dental care services (PR of 4.50). Those who were satisfied with their dental condition had lower odds of using dental care services. The bad oral odor was positively associated with the ever-use of dental care services (PR of 2.80). The use of soap for toothbrushing was positively associated with the ever-use of dental care services (PR of 2.51).

Conclusion
The study found a low frequency of dental care use among HIV-infected adolescents in Kampala, Uganda, with age being a predisposing factor. Enabling factors included fear of HIV spread, medical-dental appointment incoordination, and satisfaction with the dental condition and bad oral odor while under personal dental health practices. The use of soap for toothbrushing was an important association with dental care. Nevertheless, these study results cannot be generalized to the entire HIV adolescent population in Uganda.
Intrathecal gastrodin alleviates allodynia in a rat spinal nerve ligation model through NLRP3 inflammasome inhibition

Published: June 2024

Abstract
Background
Gastrodin (GAS), a main bioactive component of the herbal plant, Gastrodia elata Blume, has shown to have beneficial effects on neuroinflammatory diseases such as Alzheimer’s disease in animal studies and migraine in clinical studies. Inflammasome is a multimeric protein complex having a core of pattern recognition receptor and has been implicated in the development of neuroinflammatory diseases. Gastrodin has shown to modulate the activation of nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome. This study investigated the effects of GAS on the intensity of mechanical allodynia and associated changes in NLRP3 inflammasome expression at the spinal level using L5/6 spinal nerve ligation model (SNL) in rats.

Methods
Intrathecal (IT) catheter implantation and SNL were used for drug administration and pain model in male Sprague-Dawley rats. The effect of gastrodin or MCC950 (NLRP3 inflammasome inhibitor) on mechanical allodynia was measured by von Frey test. Changes in NLRP3 inflammasome components and interleukin-1β (IL-1β) and cellular expression were examined in the spinal cord and dorsal root ganglion.

Results
The expression of NLRP3 inflammasome components was found mostly in the neurons in the spinal cord and dorsal root ganglion. The protein and mRNA levels of NLRP3, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), caspase-1, and IL-1β were upregulated in SNL animals compared to Sham animals. IT administration of GAS significantly attenuated the expression of NLRP3 inflammasome and the intensity of SNL-induced mechanical allodynia. NLRP3 inflammasome inhibitor, MCC950, also attenuated the intensity of allodynia, but the effect is less strong and shorter than that of GAS.

Conclusions
Expression of NLRP3 inflammasome and IL-1β is greatly increased and mostly found in the neurons at the spinal level in SNL model, and IT gastrodin exerts a significant anti-allodynic effect in SNL model partly through suppressing the expression of NLRP3 inflammasome.
The knowledge, attitude and behavior of ICU nurses regarding ICU-acquired weakness: a cross-sectional survey
Authors: Zhao Mingfeng , Qiu Anyun , Zhang Zhijing , Pan Fang , Gao Yongxia 
Published: June 2024

Abstract
Background
Intensive care unit-acquired weakness (ICU-AW) is very common in ICU patients. It is important to understand the status quo of knowledge, attitude and behavior of ICU nurses about ICU-AW. This survey aimed to investigate the knowledge, attitude and behavior of ICU nurses about ICU-AW, to provide useful implications for clinical care.

Methods
ICU nurses from two tertiary hospitals in China from October 10 to November 15, 2023 were included. The ICU-AW knowledge, attitude and behavior questionnaire of ICU nurses with 31 items were used for survey. SPSS24.0 statistical software was used for data analysis.

Results
A total of 364 ICU nurses were included for survey. The ICU-AW knowledge of ICU nurses was 21.96 ± 5.72 (< 50% of the total knowledge score), the ICU-AW attitude of ICU nurses was 30.24 ± 5.05(< 75% of the total attitude score), the ICU-AW behavior of ICU nurses was 26.77 ± 5.81(< 75% of the total behavior score), the total score was 79.21 ± 12.69(< 75% of the total score). Nurses’ ICU-AW knowledge, attitude and behavior were all correlated (all P < 0.05). Multiple linear regression analyses indicated that age, years of ICU work experience, professional ranks and titles, had received the training about the ICU-AW were the influencing factors of knowledge, attitude and behavior of ICU nurses about ICU-AW (all P < 0.05).

Conclusions
The knowledge, attitude and behavior of ICU nurses’ ICU-AW needs to be improved, and there are many influencing factors. Hospital nursing administrators should strengthen the training of nurses’ ICU-AW knowledge and improve the cognitive and practical ability of ICU nurses on ICU-AW, so as to reduce the occurrence of ICU-AW.
Toxicological evaluation of microbial secondary metabolites in the context of European active substance approval for plant protection products
Authors: Paege Norman , Feustel Sabrina , Marx-Stoelting Philip 
Published: June 2024

AbstractRisk assessment (RA) of microbial secondary metabolites (SM) is part of the EU approval process for microbial active substances (AS) used in plant protection products (PPP). As the number of potentially produced microbial SM may be high for a certain microbial strain and existing information on the metabolites often are low, data gaps are frequently identified during the RA. Often, RA cannot conclusively clarify the toxicological relevance of the individual substances. This work presents data and RA conclusions on four metabolites, Beauvericin, 2,3-deepoxy-2,3-didehydro-rhizoxin (DDR), Leucinostatin A and Swainsonin in detail as examples for the challenging process of RA. To overcome the problem of incomplete assessment reports, RA of microbial AS for PPP is in need of new approaches. In view of the Next Generation Risk Assessment (NGRA), the combination of literature data, omic-methods, in vitro and in silico methods combined in adverse outcome pathways (AOPs) can be used for an efficient and targeted identification and assessment of metabolites of concern (MoC).

Authors: Ogawa Sayaka , Tayama Jun , Murota Hiroyuki , Kobayashi Masakazu , Kinoshita Hirohisa , Nakamichi Seiko 
Published: June 2024

Abstract
Background
Patients with primary focal hyperhidrosis (hyperhidrosis) are known to have higher levels of anxiety induced by sweating than those who do not. However, in hyperhidrosis, no scale has been developed to measure anxiety specific to hyperhidrosis symptoms. Therefore, this study aimed to develop an anxiety scale specific to hyperhidrosis symptoms (ASSHS) and to verify its reliability and validity.

Methods
Based on previous studies on hyperhidrosis and a preliminary survey conducted with 26 university students who met the diagnostic criteria for hyperhidrosis, 40 items that adequately reflected anxiety specific to hyperhidrosis symptoms were obtained. A survey was done to examine the internal consistency and validity of the our developed ASSHS. In total, 1,207 participants (680 male and 527 female; mean age ± standard deviation 18.7 ± 0.9 years) were included. A second survey (re-survey) was conducted three weeks later to verify the reliability. It included 201 participants (85 male and 116 female; mean age ± standard deviation 18.6 ± 0.7 years). The survey items included (1) the diagnostic criteria for hyperhidrosis, (2) our anxiety scale developed for primary focal hyperhidrosis symptoms (ASSHS), (3) Hyperhidrosis Disease Severity Scale (HDSS), (4) State-Trait Anxiety Inventory (STAI), (5) Hospital Anxiety and Depression Scale (HADS), (6) Dermatology Life Quality Index (DLQI), and (7) presence of anxiety induced by sweating.

Results
The results of the factor analysis revealed 10 items with one factor, “anxiety specific to hyperhidrosis symptoms.” The alpha coefficient of the ASSHS was α = 0.94. The correlation coefficient between the scores at re-test was r = 0.75. A moderate positive correlation was found between the ASSHS, HDSS (r = 0.53), and anxiety induced by sweating (r = 0.47) (all p < 0.001). Additionally, participants with hyperhidrosis symptoms had significantly higher ASSHS scores than did those without hyperhidrosis symptoms (p < 0.001). Those with mild/moderate hyperhidrosis and those with severe hyperhidrosis had significantly higher the ASSHS scores than did those without hyperhidrosis (p < 0.001).

Conclusions
This scale has sufficient reliability and validity as an instrument to measure anxiety specific to hyperhidrosis symptoms.

Published: June 2024

Abstract
Background
The aim of this retrospective cohort study was to develop and validate on multiple international datasets a real-time machine learning model able to accurately predict persistent acute kidney injury (AKI) in the intensive care unit (ICU).

Methods
We selected adult patients admitted to ICU classified as AKI stage 2 or 3 as defined by the “Kidney Disease: Improving Global Outcomes” criteria. The primary endpoint was the ability to predict AKI stage 3 lasting for at least 72 h while in the ICU. An explainable tree regressor was trained and calibrated on two tertiary, urban, academic, single-center databases and externally validated on two multi-centers databases.

Results
A total of 7759 ICU patients were enrolled for analysis. The incidence of persistent stage 3 AKI varied from 11 to 6% in the development and internal validation cohorts, respectively and 19% in external validation cohorts. The model achieved area under the receiver operating characteristic curve of 0.94 (95% CI 0.92–0.95) in the US external validation cohort and 0.85 (95% CI 0.83–0.88) in the Italian external validation cohort.

Conclusions
A machine learning approach fed with the proper data pipeline can accurately predict onset of Persistent AKI Stage 3 during ICU patient stay in retrospective, multi-centric and international datasets. This model has the potential to improve management of AKI episodes in ICU if implemented in clinical practice.
Physical rehabilitation program for cardiorespiratory health and quality of life among breast cancer survivors in UAE: protocol for a randomized control trial
Authors: Rashid Fatima Abdul , Anwar Wajiha , Kandakurti Praveen Kumar , Hazari Animesh 
Published: June 2024

Abstract
Background
Cancer is a medical condition where some cells of the body reproduce uncontrollably and metastasize to other parts of the body. The burden of the disease is significantly high both at the global and national levels. In UAE, cancer was found to be the third leading cause of death. Breast cancer has been ranked first due to its prevalence, incidence, and mortality in UAE. Breast cancer survivors have significantly poor cardiovascular tolerance which affects their quality of life (QoL), even after the carcinoma has been treated or removed. Thus, the protocol aims to analyze the changes in cardiovascular endurance and QoL domains for breast cancer survivors in the United Arab Emirates using a long-term 2-month physical rehabilitation.

Methods
A total of 60 breast cancer survivors would be included in the study using a randomized controlled allocation of a 2-month physical rehabilitation intervention program with 3 months of follow-up. The intervention would target the cardiovascular endurance component of the participants to improve their physical well-being and quality of life ultimately.

Discussion
The findings of the study would have high clinical significance among breast cancer survivors in the UAE. The proposed physical rehabilitation program could be beneficial in improving cardiovascular endurance and thereby reduce the risk of mortality among breast cancer survivors. In addition, the physiological benefits of the exercise program could improve their quality-of-life domains including physical, mental, and social well-being. On a larger view, it could also help to reduce the economic burden on the health system due to associated complications.

Published: June 2024

Abstract
Background
The interplay between Toxoplasma gondii infection and tumor development is intriguing and not yet fully understood. Some studies showed that T. gondii reversed tumor immune suppression, while some reported the opposite, stating that T. gondii infection promoted tumor growth.

Methods
We created three mouse models to investigate the interplay between T. gondii and tumor. Model I aimed to study the effect of tumor growth on T. gondii infection by measuring cyst number and size. Models II and III were used to investigate the effect of different stages of T. gondii infection on tumor development via flow cytometry and bioluminescent imaging. Mouse strains (Kunming, BALB/c, and C57BL/6J) with varying susceptibilities to tumors were used in the study.

Results
The size and number of brain cysts in the tumor-infected group were significantly higher, indicating that tumor presence promotes T. gondii growth in the brain. Acute T. gondii infection, before or after tumor cell introduction, decreased tumor growth manifested by reduced bioluminescent signal and tumor size and weight. In the tumor microenvironment, CD4+ and CD8+ T cell number, including their subpopulations (cytotoxic CD8+ T cells and Th1 cells) had a time-dependent increase in the group with acute T. gondii infection compared with the group without infection. However, in the peripheral blood, the increase of T cells, including cytotoxic CD8+ T cells and Th1 cells, persisted 25 days after Lewis lung carcinoma (LLC) cell injection in the group with acute T. gondii. Chronic T. gondii infection enhanced tumor growth as reflected by increase in tumor size and weight. The LLC group with chronic T. gondii infection exhibited decreased percentages of cytotoxic CD8+ T cells and Th1 cells 25 days post-LLC injection as compared with the LLC group without T. gondii infection. At week 4 post-LLC injection, chronic T. gondii infection increased tumor formation rate [odds ratio (OR) 1.71] in both KM and BALB/c mice.

Conclusions
Our research elucidates the dynamics between T. gondii infection and tumorigenesis. Tumor-induced immune suppression promoted T. gondii replication in the brain. Acute and chronic T. gondii infection had opposing effects on tumor development.

Published: June 2024

Abstract
Objective
Fourth-generation HIV Ag/Ab Combo assay is used for HIV screening of blood for transfusion in developing countries, however, the sensitivity of the assay is questionable during the acute phase of HIV infection. Thus, the study aimed to determine the effect of combining centrifugation with HIV-1 virion lysis on the sensitivity of the fourth-generation HIV Ag/Ab combo assay.

Results
When the 50 HIV-1 antibody-negative samples were run on the fourth-generation HIV Ag/Ab combo assay, 8 (16%) were positive following centrifugation, 13 (26%) were positive following lysis while 25 (50%) were positive after combining centrifugation with HIV-1 virion lysis.
Timely care for age-related macular degeneration: a qualitative study among retina specialists in Israel
Authors: Myers Vicki , Luxenburg Osnat , Wilf-Miron Rachel , Verbin Hani Levkovitch 
Published: June 2024

Abstract
Background
Age-related macular degeneration (AMD) affects quality of life and independence, and its incidence and prevalence are increasing due to ageing of the population. Access to effective timely treatment can improve vision and reduce incidence of blindness. This study aimed to explore the perspectives of ophthalmologists in the Israeli public healthcare system regarding timely treatment of AMD patients.

Methods
Qualitative semi-structured interviews were conducted in 2020-2021 with 22 senior ophthalmologists, from 10 general hospitals and from two HMOs, representing different geographic regions. All interviewees specialize in retinal diseases and work with AMD patients. Interviews discussed patient pathways involved in the diagnosis and treatment of AMD, access to care, and obstacles to timely care. Thematic analysis was conducted.

Results
Based on the interviews, we describe the usual referral and treatment pathways. Themes included regional disparities, long wait times in some areas, a lack of retina specialists, differences in referral pathways, inappropriate use of emergency department to obtain timely treatment, and second-line treatment not fully covered by insurance, most affecting the weakest segments of the population.

Conclusions
Loss of vision incurs high health and societal costs. In the context of insufficient medical manpower in Israel, the healthcare system will need to assess future resources to cope with accumulating burden of AMD cases over time in an ageing population. Precise referral information, and simultaneous referral to imaging and retinal clinics, may minimize delays in treatment. Awareness of AMD symptoms and the importance of early intervention could be highlighted by campaigns, particularly among high-risk groups.

Highlights
• Interviews with hospital-based and community ophthalmologists showed regional disparities in AMD treatment, with long wait times and a lack of retina specialists in some areas.
• Differences in referral pathways, inappropriate use of emergency department to obtain timely treatment, and second line treatment not fully covered by insurance were highlighted.
• The healthcare system will need to assess future resources to cope with accumulating burden of AMD cases over time in an ageing population
• Precise referral information, and simultaneous referral to imaging and retinal clinics, may minimize delays in treatment.
• Awareness of AMD symptoms and the importance of early intervention should be emphasized in high-risk groups.
The epidemiology of drug-related hospital admissions in paediatrics – a systematic review
Authors: Eberl Sonja , Heus Pauline , Toni Irmgard , Bachmat Igor , Neubert Antje 
Published: June 2024

Abstract
Background
Despite previous efforts, medication safety in paediatrics remains a major concern. To inform improvement strategies and further research especially in outpatient care, we systematically reviewed the literature on the frequency and nature of drug-related hospital admissions in children.

Methods
Searches covered Embase, Medline, Web of Science, grey literature sources and relevant article citations. Studies reporting epidemiological data on paediatric drug-related hospital admissions published between 01/2000 and 01/2024 were eligible. Study identification, data extraction, and critical appraisal were conducted independently in duplicate using templates based on the ’Joanna Briggs Institute’ recommendations.

Results
The review included data from 45 studies reporting > 24,000 hospitalisations for adverse drug events (ADEs) or adverse drug reactions (ADRs). Due to different reference groups, a total of 52 relative frequency values were provided. We stratified these results by study characteristics. As a percentage of inpatients, the highest frequency of drug-related hospitalisation was found with ‘intensive ADE monitoring’, ranging from 3.1% to 5.8% (5 values), whereas with ‘routine ADE monitoring’, it ranged from 0.2% to 1.0% (3 values). The relative frequencies of ‘ADR-related hospitalisations’ ranged from 0.2% to 6.9% for ‘intensive monitoring’ (23 values) and from 0.04% to 3.8% for ‘routine monitoring’ (8 values). Per emergency department visits, five relative frequency values ranged from 0.1% to 3.8% in studies with ‘intensive ADE monitoring’, while all other eight values were ≤ 0.1%. Heterogeneity prevented pooled estimates. Studies rarely reported on the nature of the problems, or studies with broader objectives lacked disaggregated data. Limited data indicated that one in three (median) drug-related admissions could have been prevented, especially by more attentive prescribing. Besides polypharmacy and oncological therapy, no other risk factors could be clearly identified. Insufficient information and a high risk of bias, especially in retrospective and routine observational studies, hampered the assessment.

Conclusion
Given the high frequency of drug-related hospitalisations, medication safety in paediatrics needs to be further improved. As routine identification appears unreliable, clinical awareness needs to be raised. To gain more profound insights especially for generating improvement strategies, we have to address under-reporting and methodological issues in future research.
