Abstract
AIM To investigate the effect of 38% SDF and its serial dilutions on the Stem cells from Human Exfoliated Deciduous teeth (SHED) and its ability to release growth factors from deciduous dentine. METHODS The viability of SHED post-exposure to 38%, 3.8%, 0.38%, 0.038%, and 0.0038% SDF were assessed at 2, 5, and 7 days using the CyQuant assay, and results were validated using the MTT assay. The osteogenic differentiation of the cells was also investigated post-exposure to 0.0038% SDF. The release of the growth factors; TGF-β1, FGF-b, BMP-2, and VEGF from deciduous dentin discs exposed to 38% SDF, 0.0038% SDF, Ca(OH)2, MTA, and 17% EDTA were examined using ELISA. Statistical analysis was performed using means and standard deviations (p < 0.05). Two-way ANOVA compared the means of more than two groups with Tukey's multiple comparison test. The unpaired t-test was also used to compare the differences between the two data sets. CONCLUSION 38% SDF released dentinogenic growth factors from dentin discs, potentially explaining its role in reactionary dentinogenesis. Moreover, 0.0038% SDF resulted in a non-cytotoxic concentration that enhanced cellular proliferation and released bioactive molecules from dentin comparable to the 38% concentration. After further investigations, the 0.0038% dilution of SDF could present itself as a clinical concentration.

[PMID: 38565457 DOI: 10.1016/j.clon.2024.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 02/26/2024] [Accepted: 03/12/2024] [Indexed: 04/04/2024]
Abstract
AIMS Sinonasal teratocarcinosarcomas (SNTCS) are rare sinonasal malignancies, the incidence of which is less than 1% of all tumors. There is limited data available on SNTCS's, often as case reports and small case series. The management of SNTCS is complicated because of its location, locally aggressive biology, difficulty in achieving complete resection, and limited data on chemotherapy in these malignancies. This audit was performed to understand the role of neoadjuvant chemotherapy (NACT) in SNTCS's, its ability to downstage the disease, achieve complete resection, and impact on long-term survival outcomes. METHODS This was a retrospective analysis of a prospectively maintained database approved by the Institutional Ethics Committee (IEC). The baseline characteristics, the extent of tumor, Kadish stage, NACT regimen, and adverse events were extracted from the Electronic Medical Records and the patient's case file. Patients with baseline extensive/inoperable disease were referred for NACT from the multidisciplinary joint clinic followed by response assessment (RECIST v1.1). Patients underwent skull-base surgery if respectable post-completion of NACT, however, if deemed unresectable were treated with non-surgical modalities or palliative therapies. RESULTS The data of 27 patients were evaluated from the year 2015-2022. The median age was 42 years (IQR:30-56) and 85.2% (n = 23) were males. The ECOG-PS was 0-1 in 88.8% (n = 24) patients. All 27 patients received NACT in view of extensive disease at presentation. 74.1% (n = 20) patients received Cisplatin-Etoposide and 25.9% (n = 7) received other chemotherapy regimens. The median number of chemotherapy cycles was 2(IQR:2-3). 96.3% patients (n = 26) completed the planned NACT cycles. 70.4% (n = 19) patients achieved a partial response in post-NACT imaging. 77.8% (n = 18) underwent surgery, 18.5% (n = 5) received CTRT, and 7.4% (n = 2) received definitive-RT alone. The median PFS and OS of the cohort was 19months (95%CI:12.0-25.6) and 23months (95%CI:5.94-40.06) respectively. CONCLUSION NACT is safe, feasible, and effective with significant response rates, leading to effective downstaging, resectability and improved survival in patients with locally advanced SNTCS's.

Abstract
BACKGROUND The use of systemic azithromycin (AZT) and amoxicillin/metronidazole (AMX/MTZ) as adjuncts provided additional clinical and microbiological benefits over subgingival instrumentation alone. However, the superiority of one antibiotic regimen over another has not been proven. Therefore, the aim of this systematic review and meta-analyses was to evaluate the clinical efficacy and safety of subgingival instrumentation (SI) in conjunction with the systemic use of AZT or AMX/MTZ for the treatment of periodontitis from current published literature. METHODS Electronic databases were searched to identify randomized controlled trials (RCTs), controlled clinical trials, prospective and retrospective human studies that compared the adjunctive use of systemic AZT to AMX/MTZ with SI in the treatment of periodontitis. The eligibility criteria were defined based on the participant (who had periodontitis), intervention (SI with adjunctive use of systemic AZT), comparison (SI with adjunctive use of systemic AMX/MTZ), outcomes (primary outcome: changes in probing pocket). The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. Data were analysed using a statistical software program. RESULTS Five studies with 151 participants with periodontitis were included in the present review. Of these, 74 participants received adjunctive AZT, while the remaining participants received AMX/MTZ as an adjunct to SI. The adjunctive use of AZT and AMX/MTZ had comparable changes in probing pocket depths at 1-3 months with no statistically significant difference (mean difference (MD) 0.01; 95% CI -0.20 to 0.22; P = 0.94). The adjunctive use of AZT had significantly fewer number of residual sites with probing pocket depths of ≥5 mm at 1-3 months compared to the adjunctive use of AMX/MTZ (MD -3.41; 95% CI -4.73 to -2.10; P < 0.0001). The prevalence rates of adverse events among participants who received AZT and AMX/MTZ were 9.80% and 14.8%, respectively. The meta-analysis showed that the difference between the two groups was not statistically significant (risk ratio 0.69; 95% CI 0.28 to 1.72; P = 0.43). CONCLUSIONS Within the limitation of this review, there was no superiority between AZT and AMX/MTZ in terms of mean changes in probing pocket depths, clinical attachment level, bleeding on probing at 1-3 months. AZT seem to be associated with less sites with residual probing pocket depths of ≥5 mm at 1-3 months and fewer adverse events compared with AMX/MTZ. © 2023 Australian Dental Association.

Abstract
Abstract The current research work aims to provide knowledge about the diversity of spiders’ fauna and their occurrence throughout the year from District Charsadda Khyber Pakhtunkhwa, Pakistan. Research data were collected from March-2015 to January-2017 from seven different localities of Charsadda District by using the camera, bottle, plastic bags, paraffin films, field book and 70% of ethylene alcohol and 20% of glycerine were used as chemicals. By using special identification keys, spiders were differentiated into families, genera and species. During the study time, a total of 2734 specimens of spiders were collected belonging from 35 genera, 15 families and 44 species were identified. Salticidae was the dominant family according to genera studied plus spiders samples numbers collected with 10 genera and 616 species specimens count. The high occurrence of spiders was studied during July. The result of the current study also shows a reduction of spider’s species in December due to lowering the temperature. The current study shows that Salticidae were the dominant family as capered to other species. The occurrence of spiders species greatly depends on changing the weather condition. The present study also shows great fluctuation in spider’s occurrence with changing of hot climate to colder during the study duration. Moreover, the wet season plays a great role in spiders’ population increase and growth.

Abstract
Background Abnormal uterine bleeding (AUB) is a common gynaecological condition. The levonorgestrel-releasing Intrauterine device (LNG-IUD) is an effective medical treatment. option which carries a small risk of device expulsion. For those who experience expulsion, some may benefit from a more robust surgical approach. Objectives To demonstrate the technique for suture fixation of an LNG-IUD under hysteroscopic guidance. Materials and methods: Stepwise video demonstration of the technique using a 5mm hysteroscope and a 3mm laparoscopic needle holder. The Institutional Ethical Committee was consulted, and the requirement for approval was waived because the video described a modified surgical technique. Informed consent was obtained from the patient. Main outcome measures A 35yr old parous woman with a nine-month history of AUB and severe dysmenorrhoea had an LNG-IUD sited with effective symptom relief. Unfortunately, the device was expelled six months after insertion, and she responded poorly to other medical treatments. Transvaginal ultrasonography (TVUS) suggested posterior wall adenomyosis. Considering her relief of symptoms with the LNG-IUD and history of expulsion, the patient was counselled regarding suture-fixation of the LNG-IUD. Results She was followed-up at 6 months post insertion. The LNG-IUD was noted in the uterine cavity without displacement or expulsion. Conclusion Hysteroscopy-guided suture fixation of an LNG-IUD is a minimally invasive, effective option for patients with a history of expulsion of an IUD. However, further studies are required to establish the safety and efficacy of this approach. Learning Objective To demonstrate LNG -IUD suture fixation technique using hysteroscopy for patients diagnosed with AUB and a history of device expulsion.

Abstract
PURPOSE/OBJECTIVE(S) Resection and intraoperative brachytherapy for patients with large, operable brain metastasis allows for both relief of mass effect and the delivery of radiotherapy (RT) to the resection cavity with a favorable dosimetric profile. The objective of this study was to analyze early patterns-of-care and treatment-related toxicity outcomes for brain metastasis patients treated with surgically targeted radiation therapy (STaRT) using a novel brachytherapy carrier. MATERIALS/METHODS Patients with brain metastasis, de novo and recurrent disease, who enrolled onto a prospective multi-institutional observational study (NCT04427384) were the subject of this analysis. Patients underwent resection and immediate implantation of bioresorbable, conformable, 20 mm x 20 mm x 4 mm collagen tile brachytherapy device(s) containing four uniform-intensity Cesium-131 sources. Toxicities were categorized using the CTCAE v5.0 adverse event (AE) criteria. RESULTS From 10/2020 to 01/2023, 13 participating sites enrolled and treated 48 patients with 51 metastases (13 with de novo and 35 patients with recurrent brain metastases), and 3 patients had 2 lesions implanted at the same procedure. Median age was 61 years (range: 28-80), 52% were female, and the most common primary types were lung (56%) and breast (13%). The median maximum pre-operative dimension was 3.4 cm (range: 1.7-5.7) and median pre-operative tumor volume 13.7cm3 (range: 1.7-132). 64% had received prior RT with a median time from last RT to STaRT of 14.6 months range: 3.5-57.3). Median KPS at screening was 80 (range: 50-100), and remained stable at post op visit (80, range: 50-100), and at 3-months following treatment (80, range 50-100), respectively (p>0.05). The median time for implantation was 3 minutes (range: 0.4-30). At a median follow-up of 4 months (range: <1-18), no patient experienced a radiation-attributed AE, and only 1 attributable Gr >3 AE was noted (Gr 5 intracerebral hemorrhage deemed probably related to surgery and unrelated to the implanted device). CONCLUSION Early results from this prospective multi-center trial demonstrate the feasibility and safety of STaRT. The lack of radiation-related AE, even with short follow-up, is intriguing given the relatively large lesion size and proportion of patients treated for recurrent, previously irradiated disease. Additional follow-up will provide data on tumor control outcomes and radiation necrosis rates using this novel technique.

Abstract
PURPOSE/OBJECTIVE(S) To assess the variability of dose reporting variability due to uncertainty in segmentation of Cs-131 seeds in GammaTile therapy for gliomas and brain metastases. MATERIALS/METHODS Ten patients with either glioma or brain metastases had 4-11 GammaTiles placed along resection bed during craniotomy. A dose of 60 Gy is prescribed to 5 mm depth. Each GammaTile has four Cs-131 seeds imbedded in a biodegradable collagen sponge. GammaTile Post-Op workflow in MIM Symphony software is used for post-implant dose evaluation and reporting. This workflow requires a post-surgery CT to identify seeds, and a post-surgery MR for residual disease and OAR contours. Seeds are segmented using a threshold tool. Threshold levels may change depending on the CT used, thus users need to manually change the HU threshold value in each data set. Since GammaTiles are lined along the resection bed, PTVs are generated automatically by adding 8 mm expansion on the seed contours and later combined with residual disease contours. We simulate the seed contour uncertainty by applying -0.5 mm, -1.0 mm, +0.5 mm & +1.0 mm concentric margins to the current seed contours to create 4 new seed contours per patient. New PTVs are generated by adding 8 mm expansion on the new seed contours combined with residual disease contours. PTV volume, PTV volume receiving 100% and 150% of prescription dose (V100, V150), and percentage of the prescription dose received by 90% of the PTV (D90) are calculated to evaluate dose reporting variability due to seed segmentation uncertainty. RESULTS Mean PTV volume decreases by 8.4 cc & 10.2 cc for PTVs generated from seed contours with -0.5 mm & -1.0 mm margin, respectively, and increases by 5.8 cc & 8.2 cc, respectively, when +0.5 mm & +1 mm margins are applied to the original seed contours. We observe up to 10% change in V100 due to seed segmentation uncertainty. Mean V100 increases by 4.0% (range: 0.2% - 8.9%) & 4.9% (range: 0.5% - 11.0%) for cases with -0.5 m & -1.0 mm seed margin, respectively, and reduces by 4.2% (range: 0.5% - 6.7%) & 5.9% (range: 0.6% - 10.4%) for cases with +0.5 mm and +1.0 mm seed margin, respectively. Mean D90 increases by 7.7% (range: 4.0% - 12.6%) & 9.9% (range: 4.0% - 17.4%) for cases with -0.5 m & -1.0 mm seed margin, respectively, and reduces by 5.5% (range: 3.6% - 7.8%) & 7.4% (range: 5.2% - 9.6%) for cases with +0.5 mm and +1.0 mm seed margin, respectively. We also observe up to 8.0% changes in mean V150 when margins are applied to the seed contours. CONCLUSION Our results show significant impact of seed segmentation uncertainty on dose reporting in GammaTile therapy. Variability in dose reporting parameters highlight the need for a more standardized and automated approach to seed segmentation to ensure consistent and accurate dose reporting. The current manual threshold adjustment method is subject to user dependence and therefore unreliable. Development of a more robust tool could help to minimize variability and improve reliability of dose reporting.

Abstract
BACKGROUND Respiratory tract infections (RTIs) are the most common reason for prescribing antibiotics in general practice. The COVID-19 pandemic has impacted on antibiotic prescribing and delivery of primary care in Ireland. OBJECTIVES To assess the quality of antibiotic prescribing, the impact of the COVID-19 pandemic and identify opportunities for antimicrobial stewardship (AMS) in Ireland. METHODS Point prevalence audit surveys for RTI consultations were conducted as part of a European study at three time periods: January-February 2020, March-May 2020 and March-May 2021. Antibiotic prescribing was assessed and comparisons made between the three time periods. RESULTS In total, 765 consultations were recorded, which were mainly face to face before the pandemic, but changed to predominantly remote consultations during the pandemic surveys in 2020 and 2021 (82% and 75%). Antibiotics were prescribed in 54% of RTI consultations before the pandemic. During pandemic surveys, this dropped to 23% in 2020 and 21% in 2021. There was a decrease in prescribing of Red (reserve) agents in 2021. Assessment against indication-specific quality indicators showed a high proportion of consultations for bronchitis and tonsillitis resulting in an antibiotic prescription (67% and 85%). Point-of-care testing (POCT) to aid diagnosis of RTIs were utilized in less than 1% of consultations. CONCLUSIONS During the COVID-19 pandemic, there was a reduction in antibiotic prescribing. Opportunities identified to support AMS in primary care in Ireland are targeted initiatives to reduce antibiotic prescribing for bronchitis and tonsillitis and introducing POCT to support appropriate antibiotic prescribing.

Abstract
Abstract
Background
Antimicrobial use in mental health inpatient settings has not been extensively examined in Ireland. The Healthcare-Associated Infection and Antimicrobial Use in Long-Term Care Facilities (HALT) study 2016 found that Irish long-term care facilities caring for residents with psychiatric conditions had an antimicrobial prevalence rate of 7.7%, higher than the European average of 4.9%. National community antimicrobial prescribing guidelines are available at www.antibioticprescribing.ie. In addition, a preferred antibiotic initiative for community settings advocates prescribers to choose ‘Green’ (preferred) antibiotics over ‘Red’ (reserved) agents. Reserved agents are considered to have more adverse effects, drug interactions and potential for development of antimicrobial resistance. The patient safety implications of antimicrobial stewardship along with an ageing population, and potential drug–drug interactions between many antimicrobials and psychotropic medications prompted a review of antimicrobial use practices in mental health services.
Methods
A sample of adult inpatient mental health facilities (MHF) operated by the state's Health Service Executive (HSE) were surveyed by community antimicrobial pharmacists (AMPs) between November 2021 and January 2022. AMPs reviewed patients’ medication charts for systemic antimicrobial prescriptions in the previous 30 days in addition to medical notes and laboratory results (where available). Adherence to HSE National community antimicrobial guidelines and the systems and structures in place to support antimicrobial stewardship were assessed.
Results
In total, 1003 patients in 51 MHFs were surveyed. At the time of survey, 6.3% (n=66) patients were on a systemic antimicrobial and 15% (n=153) had received a systemic antimicrobial within the previous 30 days. Prophylaxis accounted for 50% of antibiotic use (3.3% of all patients), with the most common indication being the prevention of urinary tract infection (UTI) (58%). Prophylaxis duration exceeded six months in 61% of prescriptions. The median duration of treatment courses was seven days. The proportion of ‘Green’ (preferred) antimicrobials versus ‘Red’ (reserved) antimicrobials was 58% versus 38%. Co-amoxiclav, a ‘Red’ agent was the most commonly prescribed antibiotic for treatment of infection (31%). Adherence with choice of antimicrobial agent as per national antimicrobial guidelines was 76%; adherence of dosing regimen was 75% and adherence with recommended duration was 46%. The main themes for non-adherence with choice of agent were use of unnecessarily broad spectrum agents, nitrofurantoin prescribed in renal impairment and inappropriate formulation of nitrofurantoin chosen. Dipstick urinalysis was performed routinely (on admission and/or at designated intervals) for persons asymptomatic of UTI in 53% (n=27) of MHFs.
Conclusions
This PPS established antimicrobial use practices in HSE MHFs and identified opportunities for improvement relating to the safe and optimal use of antimicrobials. Key national recommendations from this survey were:

Abstract
Background
Antimicrobial use in Irish older persons residential care facilities (OP RCFs) is higher than in other European countries. In 2020/21, for the first time, an antimicrobial pharmacist (AMP) was appointed to each community healthcare organization (CHO) to monitor, develop and promote antimicrobial stewardship in community settings.
Objectives
To establish baseline antibiotic use, develop antimicrobial stewardship tools for OP RCFs, promote best practice in relation to antimicrobial stewardship (AMS) and monitor trends in antimicrobial use in HSE (state-run) OP RCFs.
Methods
A baseline point prevalence survey (PPS) of antimicrobial use was conducted across all HSE OP RCFs between October 2020 and August 2021. Following the survey, key national recommendations and AMS resources were developed in collaboration with the national Antimicrobial Resistance and Infection Control Programme. Feedback was provided to participating facilities by CHO AMPs with antimicrobial stewardship support and education for nursing and medical staff. In September 2021, monthly monitoring of antibiotic use was established in HSE OP RCFs in collaboration with local managers, to capture the proportion of antibiotics used for prophylaxis or treatment each month.
Results
A baseline PPS of antimicrobial use in 2020/21 showed that 11.9% (528/4446) of residents were on a systemic antibiotic, with 6.3% on antibiotic prophylaxis. Urinary tract infection accounted for 51% of antibiotic prescriptions. Following the baseline PPS, CHO AMPs developed an AMS toolkit for OP RCFs, engaged with nursing and medical staff to communicate PPS results, AMS resources and support implementation of AMS recommendations. Subsequently, monthly self-reporting of antimicrobial use in HSE OP RCFs was commenced in September 2021 and showed a sustained decrease in antimicrobial use with 7.9% residents on an antibiotic in Quarter 2 2022, with 2.7% on antibiotic prophylaxis.
Conclusions
Newly appointed CHO AMPs have successfully promoted AMS across HSE OP RCFs. Following audit, feedback, education, development and promotion of antimicrobial stewardship resources, there was a sustained decrease in the proportion of residents on antibiotics used for treatment and prophylaxis of infection.

Abstract
BACKGROUND Dislocation following hip hemiarthroplasty is a major complication with increased mortality and morbidity. Data looking at dislocation following contemporary bipolar stems are lacking in literature. METHODS Retrospective review of our prospective national hip fracture database over a two-year period. Group 1 comprised of consecutive patients receiving bipolar Furlong prosthesis (N222) while Group 2 was made up of a historical cohort (uncemented; N254). Clinical and radiological records were reviewed to determine dislocation rates, causes and associative factors of dislocations. Data were analysed using SPSS. RESULTS Following 476 hemiarthroplasties performed during the study period, 12 (2.5%) dislocations were reported (eight in Group 1; four in Group 2). There was no significant difference in dislocation rates (3.6% vs 1.6%) between groups (p = 0.159). Subgroup analysis of Group 1 demonstrated a significant difference in dislocations with Furlong cemented (6%) as compared with Furlong uncemented (0%) hemiarthroplasties (p = 0.024). Following dislocation, death rates increased to 8.3% from 1.7% in both groups. CONCLUSION There is a statistically significant increase in dislocation rate following use of cemented Furlong prosthesis when compared to similar uncemented prosthesis at the same treatment period. However, when compared to traditional uncemented prosthesis, there is no difference in dislocation rates.

Abstract
Abstract
Background
The HALT study in 2016 found that residents in Irish OPS RCFs were twice as likely to be on systemic antimicrobial compared with European average (10% v 5%). National antibiotic prescribing guidelines are available at www.antibioticprescribing.ie and prescribers are encouraged to choose ‘green’ (preferred) over ‘red’ (reserved) agents. HSE Community Antimicrobial Pharmacists (AMPs) have been employed since 2020. We aimed to establish the quality and quantity of antimicrobial prescribing in OPS-RCFs to inform antimicrobial stewardship activities.
Methods
All residents in HSE OPS-RCFs were surveyed between October 2020 and August 2021. AMPs reviewed all medication charts for systemic antimicrobials prescribed within previous 30 days. Medical notes +/- laboratory results were reviewed for persons on antimicrobials. Adherence to guidelines was assessed and information obtained on practices related to antimicrobial use.
Results
The survey included 4,448 individuals in 121 OPS RCFs. 12% were on systemic antimicrobial at time of survey. 27% received an antimicrobial in the previous 30 days. 50% of antibiotic use on survey day was for prophylaxis (6.3% of all residents). Prophylaxis exceeded 6 months in 66% persons, and 12 months in 57%. There was high usage of green versus red agents (65% vs 30%). Co-amoxiclav (red) was most commonly prescribed antimicrobial to treat infection (19%). 42% of sites reported routine use of dipstick urinalysis to support diagnosis of UTI in asymptomatic residents. 36% of sites did not have onsite electronic laboratory access. 61% of facilities did not record residents’ pneumococcal vaccination status.
Conclusion
Key national recommendations: Review all UTI prophylaxis within 6 months of initiation with view to de-prescribing.Cease routine use of dipstick urinalysis to support diagnosis of UTI for asymptomatic persons.Electronic access to laboratory results on-site required to support timely decision-making.All staff should be aware of the national antimicrobial guidelines.Pneumococcal vaccine status should be determined, and provided as necessary.

Abstract
Abstract
Poor access to quality health services, especially in urban slums, is a global challenge. Given similar challenges in Nairobi's Kibra informal settlement area, we collaborated with the Langata/Kibra sub-county health management team to conduct a pilot program for improving the quality of child health services delivered by health care providers (HCPs). The pilot introduced a digital mHealth platform to HCPs working in Kibra informal settlement area in Nairobi. This mHealth platform was compliant to WHO's recommended guideline for integrated management of newborn and child illnesses (IMNCI) and was designed to help sick child assessment, diagnosis and management by HCPs. We aimed to determine if using this digital platform, coupled with supportive supervision and community outreach, would lead to improve compliance to the IMNCI guideline for assessment, diagnosis and treatment of sick children. We conducted baseline (February 2019) assessment, trained selected HCPs on the mHealth platform on handheld android tablets, conducted end line (March 2020) and measured any change in HCP's compliance to IMNCI guidelines. Total 89 HCPs were the mHealth platform users during end line assessment. When asked about the choice of antibiotic for treating childhood pneumonia, we found proportion of HCPs who preferred Amoxycillin dispersible tablet, the recommended treatment for childhood pneumonia, increased from 3% at baseline to 38% at end line. Proportion of HCPs who were aware that antibiotics should NOT be used for the management of simple diarrhea increased from 14% (at baseline) to 50% (at end line). At end line, more than 90% HCPs were found compliant in their practice to IMNCI guidelines for sick child assessment, diagnosis and management. These results demonstrate the use of the IMNCI compliant mHealth platforms as a potential important effective way to improve capacity and compliance among HCPs who are serving communities like Kibra informal settlement in Nairobi, Kenya.
Key messages
• WHO recommended IMNCI compliant mHealth platform enables health care providers to offer quality child health care.
• Using mHealth platform to ensure WHO’s IMNCI guideline implementation by health care providers might have potential impact on saving sick children’s lives from preventable deaths.

Abstract
Abstract
World Health Organization recommends guideline for integrated management of childhood illnesses (IMCI) where Amoxicillin Dispersible Tablet (DT) appears as the first drug of choice for treating childhood pneumonia. The Government of Bangladesh adopted the IMCI strategy in 1998, and scaled it up nationwide by 2014. But, even today, the use of Amoxicillin DT, either in public or private sector, for managing childhood pneumonia is a rare event in Bangladesh. We conducted this exploratory study to understand the existing barriers, both in public and private sector, those have influences on reduced availability of Amoxicillin DT and non-compliance of health service providers to follow IMCI guideline by using Amoxicillin DT for treating a child with pneumonia, in Bangladesh. We conducted desk review of relevant strategy and policy documents, key informant interviews with 19 key individuals from Ministry of Health and national / international NGOs. Collected information were analyzed and interpreted using thematic analysis method. Identified barriers through this study pointed to inadequate policy level focus on IMCI implementation, non-inclusion of Amoxicillin DT in the national essential drug list, single source of Amoxicillin DT producing pharmaceutical in the country coupled with bureaucracy and procurement procedural complexity, lack of training of health service providers and abundant availability of antibiotic over the counter. Study respondents recommended for policy level strengthening of IMCI program, increasing coverage of training for health care provider, including practicing pediatricians both at public and private sectors, facilitating production and procurement procedures and prohibiting antibiotic sell over the counter.
Key messages
• Facilitation of production and procurement procedure coupled with enforcement of law prohibiting antibiotics availability over the counter are urgent needs.
• Policy level support emphasizing full compliance of service providers for quality of implementation of IMCI program in Bangladesh (and similar other settings) is also important.

Abstract
Abstract
Background
Despite effective therapies, the economic burden of heart failure with reduced ejection fraction (HFrEF) is driven by frequent hospital attendances [1]. Treatment optimisation and admission avoidance relies on frequent symptom review and monitoring of vital signs [2]. RM programmes aim to prevent admissions and improve system efficiency by enabling self-management [3]. Few studies evaluate the economic impact of RM in HFrEF, compared to real-world matched controls [4]. We compare hospital attendances and costs between patients using Luscii, a novel smartphone-based RM platform, and matched controls receiving usual care for 3 months.
Purpose
To assess the impact of RM on emergency department (ED) attendances, unplanned admissions and associated healthcare costs over 3 months.
Methods
A retrospective cohort study of new HFrEF referrals to our service was undertaken using the Discover dataset [5] for two cohorts (i) “RM group”: patients who used the RM platform for at least 3 months and (ii) “control group”: consecutive patients referred before the RM platform was available. The groups were matched 1:1 for age, sex, ethnicity, New York Heart Association grade and left ventricular ejection fraction. Medical co-morbidities, ED attendances, unplanned admissions and costs were extracted over 3 months from platform onboarding (RM group) or accepted referral (control group). Platform costs were added for the RM group. Differences between outcomes were analysed using t-tests, Kaplan-Meier event analysis and Cox's proportional hazard modelling.
Results
146 patients (mean age 63 years; 23% female) were included in the analyses (73 “RM group”; 73 “Control group”). The groups were well-matched for all baseline characteristics except hypertension (p=0.03). Compared to the control group, after 3 months follow-up the RM group had significantly fewer ED attendances (p<0.01) and unplanned admissions (p<0.01). Accounting for RM platform costs, there was no difference between ED costs (p=0.42), but significantly lower unplanned admissions costs in the RM group (p=0.02) (Table 1). RM was protective against ED attendances (HR=0.43, p=0.02) and unplanned admissions (HR=0.26, p=0.02), which was sustained after controlling for hypertension (Table 1). Kaplan-Meier analyses found significantly lower probability of ED attendances (p=0.02) and unplanned admissions (p=0.01) in the RM group (Figure 1).
Conclusions
HFrEF patients with RM were half as likely to attend ED and approximately four times less likely to need short-term unplanned admissions. The economic benefit of RM is driven by lower unplanned admission costs; the cost benefit is equivocal at the ED stage. Participants were younger than the typical HFrEF cohort. RM use could free up valuable resources to enhance standard care for older patients who decline or are unable to use RM. Further evaluation is required of the long-term impact of RM and its effect on outpatient encounters and costs.

Abstract
Abstract
Introduction
Device related thrombus (DRT) has been reported in up to 7% of patients post LAAC even while on anticoagulation. Clinical predictors of DRT are poorly understood and may be related to patient, procedural and device factors. A next generation WATCHMAN LAAC device (NG) is identical in shape and geometry to the current WATCHMAN FLX device (CW) but has a device coating designed to make it hemocompatible and less thrombogenic.
Objective
To evaluate the incidence and burden of WM surface thrombus formation as detected longitudinally by TEE and at necropsy in a canine model implanted with the NG device.
Methods
The study included 12 canine (6 implanted with CW and 6 implanted with NG) that underwent serial TEE follow up at 14, 28 and 45 days to evaluate surface thrombus on WM face. This was a challenged canine model designed to induce thrombus with no anticoagulation or antiplatelet use throughout the study. D-dimer levels were measured at 7 days and 45 days and compared to baseline measurements.
Results
All devices were successfully implanted. TEE follow up at 14 days showed noticeably reduced thrombus burden on the NG device compared to CW (fig.1) with even further diminution by 28 days in the NG (6/6) as compared to only in 1/6 in the CW group (fig.2). After 45 days in-life, the post-fixation trim en-face images show a smooth, glistening neoendocardial covering (absence of acute thrombus material) in all (6/6) NG compared to only 2/6 in the CW (fig.3). The CW had 3/6 devices with exuberant, bulging calcified thrombus mass one of which was considered to be a mobile DRT. D Dimer levels at 7 and 45 days were significantly lower relative to baseline in the NG compared to CW.
Conclusion
The NG device compared to the CW device was associated with markedly less thrombus formation at 14 days and no thrombus formation at 28 days post implant on no anticoagulant and no antiplatelet therapy along with a more mature uniform tissue coverage at 45 days. The WATCHMAN FLX Pro device coating is a promising step to reduce DRT even without the use of anticoagulation and antiplatelets and merits further investigation in human studies.

Abstract
Abstract
Background
Aortic emergencies, dissection and rupture, are rare but catastrophic entities, with the cornerstone to survival being prompt diagnosis and treatment. Insurance status often limits access to healthcare, and our study aims to determine if it plays a role in the outcomes of aortic emergencies.
Method
A retrospective analysis of the 2019 Nationwide Inpatient Sample was conducted to identify hospitalization (Age ≥18 & non-elective) with aortic dissection and ruptured aortic aneurysms using ICD-10 codes. Discharge-level weight analysis was used to produce a national estimate. Variables were screened with univariate regression, and intermediate and co-linear variables were screened-out before a multivariable regression analysis model was built and performed to calculate the odds ratio.
Results
A total of 19,685 (0.06%) hospitalizations are identified for aortic emergencies (14965 dissections & 4720 ruptured aneurysms). The mean age was 58.56, 62.7% were males, and ethnic distribution was 65.1% white, 19.5% blacks, 7.6% Hispanics, and others.
11.4% of the hospitalizations underwent diagnostic imaging with either CTA/MRA/TEE/Aortography within 24 hours. Hypotension/shock was present in 32% of these hospitalizations and was a risk factor for mortality OR 3.21 (p<0.00), increasing LOS by an average of 5.1 days and resource utilization by 156,000$. Another risk factor for mortality was stroke/TIA (OR-1.76, p<0.00), increasing LOS and resource utilization by 3.1 days and 80,662$, respectively.
3220 hospitalizations (16.4%) did not survive the course, and the mortality rate in uninsured, Medicare, and Medicaid was 17%, 20%,9% compared with 12% in privately insured. On crude analysis, uninsured and medicare patients appeared to have higher odds of mortality [OR 1.50, p<0.04, and OR 1.83 p-value <0.002 respectively], however upon adjusting for confounders, only uninsured patients showed statistically significant difference (OR 2.13, p<0.002). Similar results were corroborated on analyzing hospitalizations for aortic dissection; however, insurance status did not influence mortality in a ruptured aneurysm.
When comparing hospitalization of median household income of ≥79,000$ with household of median income of 59,000–78,999 $, 46,000–58,999 $ and <46,000$ had higher odds of mortality (OR-1.38, p<0.04), (OR-1.44, p<0.02) and (OR-1.44, p<0.03) respectively. Of all the insurance types, a statistically significant difference compared with private insurance, Medicaid on average, had 2.8 more days and incurred an additional 62,912$ in resource utilization (p<0.00).
Conclusion
Inequalities in accessing healthcare, median household income, and insurance status are risk factors for mortality in aortic emergencies. Efforts are needed to bridge the gap in this particular facet of social determinants of health to find a sustainable and equitable solution for quality healthcare for aall regardless of their insurance status.

Abstract
Abstract
Background
Cardiac graft failure may require repeat heart transplantation (HTx). Outcomes of patients that undergo repeat HTx have not been well described.
Methods
We compared patients that received repeat HTx with patients that received initial HTx by inquiring the United Network for Organ Sharing database between 2015–2021. The primary endpoint was all-cause mortality.
Results
A total of 19,805 HTx patients were included in the study. Patients that underwent repeat HTx (n=578, 3%) were younger (43.8±15.3 vs. 53.7±12.7 years, p<0.001) with lower body mass index (26.8±5.3 vs. 27.6±4.9 kg/m2, p<0.001) and worse renal function (Cr 1.8±1.4 vs. 1.4±0.9 mg/dl). Patients with repeat HTx had increased risk for 1-year mortality (hazard ratio 1.49 [1.16–1.90], p=0.002) compared to patients with initial HTx after adjusting for age, ethnicity, use of left ventricular assist device, UNOS recipient status, diabetes, ischemic time, donor age and predicted heart mass mismatch (Figure 1). Results did not change with the new allocation system (10/2018).
Conclusion
Repeat HTx occurred in 3% of a contemporary UNOS cohort and carried an increased and independent risk for mortality.
