Assessment of Cardiopulmonary Resuscitation Knowledge Among Physicians in the Pediatrics Department of an Urban Tertiary Referral Hospital in Ethiopia: A Cross‐Sectional Study
Authors: Dinberu Muluwork Tefera , Yemane Dagmawi Hailu 
Published: October 2024

Background: Early recognition of cardiac arrest and prompt start of cardiopulmonary resuscitation (CPR) boost survival rates and reduce postarrest consequences. Little information is available about the fundamental CPR knowledge of healthcare workers who work with children in Ethiopia.Methods: All physicians, regardless of seniority, participated in this cross‐sectional survey from June to August 2022. They received a structured survey that was modified from the American Heart Association (AHA) Basic Life Support (BLS) test which was made up of 10 questions about participants’ job experience and 25 multiple‐choice CPR knowledge questions. Data analysis was done using a multinomial logistic regression test with a p value of 0.05.Result: One hundred sixty‐eight doctors with various levels of seniority participated in this study. The participants included a male‐to‐female ratio of 1.3:1, a median age of 28 years, 92 (57.9%) male participants, and 124 (78%) participants with less than 5 years of clinical experience. Ninety‐seven participants, or 61%, had scored less than 75% whereas 13 (8.2%), participants, had good knowledge that is scoring above 75%. Participants who had training in CPR within the previous year showed significantly higher levels of knowledge than those who hadn’t. Even though 90% of the participants claimed to have CPR knowledge, the majority of participants were found not to have below 75%.Conclusion: The study concludes that while many doctors believe they have adequate CPR knowledge, actual knowledge levels are insufficient. Staff should undergo regular certification and assessments to ensure they retain their resuscitation knowledge. This ongoing evaluation is crucial for maintaining high standards of care and preparedness in emergencies.

Background It is unclear how rising obesity among people with HIV (PWH) impacts their risk of type 2 diabetes mellitus (diabetes). We examined associations between HIV, prevalent diabetes and adiposity among South African PWH and their peers without HIV (PWOH). Methods HIV status was ascertained by antibody testing. Diabetes was defined as current use of oral hypoglycemics, insulin, and/or HbA1c ≥6.5%. Adiposity was measured by body mass index (BMI), waist circumference and waist-to-height ratio. Their associations were examined using sex-stratified multivariable fractional polynomial generalized linear models, reporting adjusted prevalence and prevalence ratios (adjPR). Results The mean age among 1,254 PWH and 4,381 PWOH was 41 years (95%CI 28, 56). The prevalence of diabetes among males was similar between PWH [11.3% (7.1, 15.5)] and PWOH [9.8% (8.5, 11.1); p=0.740]. By contrast, diabetes prevalence was higher among female PWOH [15.7% (14.4, 17.0)] than female PWH [10.5 (8.3, 12.8)%; adjPR: 0.67 (0.51, 0.82); p<0.001]. This difference was accentuated with obesity but reversed with leanness. At BMI ≥25 kg/m2, female PWH had lower diabetes prevalence [adjPR: 0.58 (0.41, 0.76); p<0.001] than female PHIV. In contrast, at BMI <18 kg/m2, female PWH had higher prevalence [adjPR: 1.72 (−1.53, 4.96); p=0.756] than female PWOH. Conclusion We found sex-specific differences in the relationship between adiposity and diabetes prevalence by HIV serostatus in South Africa. Notably, females living with obesity and HIV had lower prevalence of diabetes than females living with obesity and without HIV, which may have particular implications for diabetes prevention programs in the region.

Published: October 2024

Abstract
Background
In the demanding environment of the neonatal intensive care unit (NICU), quality nursing care hinges on effective teamwork and communication among nurses. However, this requirement for close cooperation can expose nurses to significant levels of moral distress. This study aims to explore the connection between the quality of teamwork and the experience of moral distress among NICU nurses.

Methods
Employing a cross-sectional, multicenter descriptive correlational design, this study surveyed female NICU nurses across the cities of Khorramabad and Semnan. Census sampling was utilized over five months, from July to November 2023, resulting in the participation of 190 nurses. Tools for data collection included demographic questionnaires, the Team-STEPPS Teamwork Perception Questionnaire (T-TPQ), and the Moral Distress Scale-Revised (MDS-R) for nurses.

Results
The findings revealed an average teamwork score of 3.73 ± 0.78, denoting an acceptable level, and an average moral distress score of 91.2 ± 56.7, indicating a low level. In multiple linear regression, marital status showed a direct positive correlation (β = 38.5, SE (β) = 9.3, p < 0.001), while the number of children (β = -14.6, SE (β) = 4.9, p = 0.003) and the teamwork score (β = -1.1, SE (β) = 0.12, p < 0.001) were inversely correlated with moral distress.

Conclusion
The study’s results suggest that stronger teamwork among nurses correlates with reduced moral distress. Enhancing teamwork within NICUs could lead to policy development focused on the safety and quality of newborn care, also potentially alleviating moral distress experienced by nurses.
Methods to optimize optical sensing of biotic plant stress – combined effects of hyperspectral imaging at night and spatial binning
Authors: Nansen Christian , Savi Patrice J. , Mantri Anil 
Published: October 2024

AbstractIn spatio-temporal plant monitoring, optical sensing (including hyperspectral imaging), is being deployed to, non-invasively, detect and diagnose plant responses to abiotic and biotic stressors. Early and accurate detection and diagnosis of stressors are key objectives. Level of radiometric repeatability of optical sensing data and ability to accurately detect and diagnose biotic stress are inversely correlated. Accordingly, it may be argued that one of the most significant frontiers and challenges regarding widespread adoption of optical sensing in plant research and crop production hinges on methods to maximize radiometric repeatability. In this study, we acquired hyperspectral optical sensing data at noon and midnight from soybean (Glycine max) and coleus wizard velvet red (Solenostemon scutellarioides) plants with/without experimentally infestation of two-spotted spider mites (Tetranychus urticae). We addressed three questions related to optimization of radiometric repeatability: (1) are reflectance-based plant responses affected by time of optical sensing? (2) if so, are plant responses to two-spotted spider mite infestations (biotic stressor) more pronounced at midnight versus at noon? (3) Is detection of biotic stress enhanced by spatial binning (smoothing) of hyperspectral imaging data? Results from this study provide insight into calculations of radiometric repeatability. Results strongly support claims that acquisition of optical sensing data to detect and characterize stress responses by plants to detect biotic stressors should be performed at night. Moreover, the combination of midnight imaging and spatial binning increased classification accuracies with 29% and 31% for soybean and coleus, respectively. Practical implications of these findings are discussed. Study results are relevant to virtually all applications of optical sensing to detect and diagnose abiotic and biotic stress responses by plants in both controlled environments and in outdoor crop production systems.
Gastric metastasis from renal cell carcinoma with submucosal invasion treated by surgical full-thickness resection: a case report
Authors: Magara Nanako , Takahashi Naoto , Takano Yuta , Takeshita Kenji , Toya Naoki , Yano Fumiaki , Eto Ken 
Published: October 2024

Abstract
Background
Metastatic gastric tumors are rare and malignant melanoma, breast cancer, lung cancer, and esophageal cancer are common as primary lesions. On the other hand, renal cell carcinoma is easy to metastasize hematogenously to the whole body. However, metastasis to the stomach is rare and the detailed treatment of gastric metastasis is not mentioned. In this study, we report an uncommon case of gastric metastasis from renal cell carcinoma that underwent surgical full-thickness resection and reviewed the literature for treatment options.

Case presentation
The patient was a female in her 60s and in January 2007, she underwent a transabdominal left nephrectomy for clear cell carcinoma of the left kidney. The pathological diagnosis was pT2N0M0 stage II. In October 2017, a total pancreatectomy with D2 dissection was performed for multiple pancreatic masses, in which the pathological diagnosis was pancreatic metastasis of renal cell cancer. In May 2019, an esophagogastroduodenoscopy for heartburn revealed redness and erosion in the greater curvature of the residual gastric body. The pathological diagnosis was gastric metastasis from renal cell carcinoma. No metastatic findings were observed and gastric wedge resection was performed. Pathological diagnosis of the resected specimen showed a 4-mm tumor, mainly within the mucosa and partly extended to the submucosal layer in 500 µm. The resected specimen had a clear resection margin.

Conclusions
In this study, we report a case in which a full-thickness resection was performed for gastric metastasis 12 years after renal cancer surgery and 2 years after pancreatic metastasis surgery. The patient survived 4 years and 8 months after gastric wedge resection. Although gastric metastasis often takes the form of submucosal tumors, it is necessary to select full-thickness resection for R0 resection, even in small and flat lesions.

Abstract
Background
COVID-19 has significant effects on organ function, particularly on lung function and iron metabolism. Studies have shown increased levels of ferritin, an iron storage protein, in COVID-19 patients, indicating potential changes in iron utilization. Research has focused primarily on adults, with limited studies on paediatric patients and a lack of comparisons with MIS-C patients. This study aimed to assess iron status in paediatric COVID-19 patients using traditional and new biomarkers, soluble transferrin receptors (sTfR) and Reticulocyte hemoglobin equivalent (RET-He), to improve diagnosis and prognosis. Additionally, we sought to compare iron status between acute COVID-19 patients and MIS-C patients and evaluate the relationships among iron dysmetabolism, disease severity, and prognosis in paediatric patients. The study also involved monitoring iron status during and after infection to understand its impact on patient severity and prognosis.

Methods
A cohort study involving 49 patients aged 1 month to 18 years was conducted at the isolation department of Mansoura University Children's Hospital. The study included 36 patients with acute COVID-19 and 13 with multisystem inflammatory syndrome of childhood (MIS-C). Diagnosis was based on PCR from a deep nasopharyngeal swab or a positive antibody test. Follow-up of survivors was conducted 3 months after recovery. Blood samples were obtained during infection and at follow-up for CBC, Ret-He, iron kinetics, and sTfR analyses.

Results
Significant iron deficiency anaemia was observed in all patients during infection, with improvement after 3 months of recovery in survivors. The improvement was more obvious in MIS-C patients, with Hb and iron kinetics not significantly affected by disease severity. The STfR was significantly lower in nonsurvivors than in survivors. The ROC curve showed that a baseline sTfR ≤ 18 nmol/L was a statistically significant difference between nonsurvivors and survivors (area under the curve (AUC) = 0.810, p < .001), with 66.7% sensitivity and 82.5% specificity. Regression analysis revealed that patients with baseline sTfRs ≤ 18 nmol/L were 5.9 times more susceptible to death.

Conclusion
This study revealed that COVID-19 in children caused iron deficiency anaemia, which improved within 3 months after recovery. Haemoglobin and sTfRs were identified as reliable indicators of IDA in these patients, unlike iron kinetics and RET-He.
Organizacja bezpieczeństwa granic w I Rzeczypospolitej
Authors: Wawrzusiszyn Andrzej 
Published: October 2024

Wraz z rozwojem osadnictwa wytyczano granice, a umacnianie porządku władzy plemiennej pozwalało powiększać zajmowane tereny oraz skuteczniej nimi zarządzać. Pierwsze granice były granicami naturalnymi i przebiegały wzdłuż rzek, szczytów górskich, lasów, wybrzeży mórz itp. Granica stanowiła pas przejściowy znajdujący się na krańcach władztwa poszczególnych plemion czy włodarzy. Z upływem czasu granice chroniono nie tylko dzięki naturalnym przeszkodom, ale budowano systemy obronne w postaci grodów, wałów ziemnych, zasieków i innych umocnień.
Celem rozważań jest organizacja zabezpieczenia granic państwa polskiego w okresie I Rzeczypospolitej wobec zmian zachodzących w środowisku bezpieczeństwa zewnętrznego i wewnętrznego. W aspekcie metodologicznym wykorzystana została metoda historyczna i komparatystyczna w oparciu o analizę materiałów źródłowych i literaturę przedmiotu. Wynikiem powyższego jest stwierdzenie, że granice I Rzeczypospolitej formowały się różnie i podlegały znacznym zmianom, zapewniając bezpieczeństwo państwu i jego obywatelom na zróżnicowanym poziomie.
Strategic Expert Committees and the Markets That Assess Them: A Laboratory Experiment
Authors: Renes Sander , Visser Bauke 
Published: October 2024

Committees of experts are widely used to make decisions. We experimentally investigate the relationship between decision making in committees and the assessment of the ability of committee members by evaluators, comparing observed behavior with theoretical predictions. Treatments vary in whether members care only about a state-dependent project payoff or also about assessments and whether evaluators can base their assessments only on the decision the committee makes or also on cheap-talk statements made by committee members on their confidence in the committee decision. Evidence for the equilibrium predictions is mixed; for example, contrary to theory, committees with a concern for their assessment do not distort their decisions more than committees without, whereas in line with theory, evaluators give higher assessments to committees that take the risky decision rather than the riskless. We analyze whether evaluators rationally base their assessments on observed behavior of committees using an orthogonality test. In treatments with cheap-talk statements, assessments are quite rational; in treatments without, they are too low on average. We investigate whether committees best reply to expected project payoffs and, in treatments in which members’ payoffs also depend on assessments, to predicted assessments conditional on observed committee behavior. In all treatments, committees respond to the possibilities to raise expected payoffs but do not use them as much as predicted by theory. We conclude by showing that the amount of information about committee members’ abilities that ends up in assessments is considerably larger when evaluators observe committees’ decisions and statements rather than only decisions.

Can Random Friends Seed More Buzz and Adoption? Leveraging the Friendship Paradox
Authors: Kumar Vineet , Sudhir K. 
Published: October 2024

A critical element of word of mouth (WOM) or buzz marketing is to identify seeds, often central actors with high degree in the social network. Seed identification typically requires data on the relevant network structure, which is often unavailable. We examine the impact of WOM seeding strategies motivated by the friendship paradox, which can obtain more central nodes without knowing network structure. Higher degree nodes may be less effective as seeds if these nodes communicate less with neighbors or are less persuasive when they communicate; therefore, whether friendship paradox–motivated seeding strategies increase or reduce WOM and adoption remains an empirical question. We develop and estimate a model of WOM and adoption using data on microfinance adoption across village social networks in India. Counterfactuals show that the proposed strategies with limited seeds are about 13%–30% more effective in increasing adoption relative to random seeding. These strategies are also on average 5%–11% more effective than the firm’s leader seeding strategy. We also find these strategies are relatively more effective when we have fewer seeds.

Efficacy of a gelling-fibre dressing and a gelling-fibre dressing with silver nanoparticles at controlling exudate and infection: a 4-week multicentre clinical evaluation
Authors: Fong Choi Ching , Graham Anna , Hamilton Sandie , Jelly Melissa , Linsley James , Perry Hannah , Weaver Hilary 
Published: October 2024

Background: Suprasorb Liquacel Pro (standard test dressing) and Suprasorb Liquacel Ag (test dressing with silver nanoparticles) are absorptive gelling-fibre dressings designed to manage wound exudate levels and promote moist wound healing, with the latter having additional antimicrobial properties. Aims: To assess the impact of the test dressing on healing, exudate levels and signs of infection. Methods: Patients with moderately-to-highly exuding hard-to-heal wounds of any type were dressed with the standard test dressing or the test dressing with silver nanoparticles if they showed covert or overt signs of local infection. Comparative data were collected at baseline and 4-week conclusion. Adverse events and patient and professional opinions were also reported and collated. Findings: There were 19 patients with lower-limb wounds of various types present for a mean of 26 months. At baseline, most wounds were deteriorating or static (68%), while at conclusion most were improving or healed (84%), with additional indicators of improved healing. The number of patients with moderate-to-high exudate levels decreased from 84% to 53%. The 15 patients using the test dressing with silver nanoparticles saw reductions in covert signs of infection from 93% to 80%, overt signs of infection from 33% to 13% and antibiotic use from 13% to 7%. Conclusions: On average, the test dressings were effective in managing and reducing the barriers to healing, including high exudate, infection and biofilm, and in restarting stalled healing.
Effects of upper thoracic Mulligan mobilization on pain, range of motion and function in patients with mechanical neck pain: A randomized placebo-controlled trial
Authors: Cevik Ramazan , Pala Omer Osman 
Published: October 2024

Objective
This study aimed to assess the impact of Mulligan Reverse Natural Apophyseal Glides (RNAGS) applied to the upper thoracic region on pain, movement limitation, and function in individuals with mechanical neck pain.

Methods
Conducted between January 2021 and May 2021, the study involved 69 participants randomly assigned to a sham group, physiotherapy group, and Mulligan group. A two-week, 11-session treatment program was administered with shared physiotherapy interventions and stretching exercises to all groups. The Mulligan group received additional mobilization with the Mulligan RNAGS technique. The sham group received sub-standard Mulligan mobilization. Outcome measures included Range of Motion (ROM), Visual Analogue Scale (VAS), and Neck Disability Index (NDI).

Results
No baseline differences were found in measurements among the groups. After the intervention, all groups showed increased ROM and decreased VAS and NDI scores (p<0.001). The Mulligan group exhibited significantly greater improvement in VAS, ROM, and NDI compared to other groups (p<0.001). The sham group demonstrated greater improvement in NDI and extension ROM compared to the physiotherapy group (p<0.001).

Conclusion
Mulligan RNAGS technique in the upper thoracic region proved beneficial for pain relief, range of motion, and functionality in mechanical neck pain. Long-term effects warrant further exploration through population-based studies.

Authors: Abed Sahar , Beig Masoumeh , Barzi Seyed Mahmoud , Shafiei Morvarid , Hashemi Shahraki Abdolrazagh , Sadeghi Sara , Sohrabi Aria 
Published: October 2024

Background
Chronic wound infections caused by Enterococcus faecalis pose formidable challenges in clinical management, exacerbated by the emergence of vancomycin-resistant strains. Phage therapy offers a targeted approach but encounters delivery hurdles. Due to their biocompatibility and controlled release properties, hydrogels hold promise as carriers.

Objective
This study aimed to fabricate phage-containing hydrogels using sodium alginate (SA), carboxymethyl cellulose (CMC), and hyaluronic acid (HA) to treat E. faecalis-infected wounds. We assessed the efficacy of these hydrogels both in vitro and in vivo.

Methods
The hydrogel was prepared using SA-CMC-HA polymers. Phage SAM-E.f 12 was incorporated into the SA-CMC-HA hydrogel. The hydrogel’s swelling index was measured after 24 h, and degradation was assessed over seven days. Surface morphology and composition were analyzed using Scanning Electron Microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). Antibacterial activity was tested via optical density (OD) and disk diffusion assays. Phage release and stability were evaluated over a month. In vivo efficacy was tested in mice through wound healing and bacterial count assays, with histopathological analysis.

Results
Hydrogels exhibited a swelling index of 0.43, a water absorption rate of %30, and 23% degradation over seven days. FTIR confirmed successful polymer incorporation. In vitro studies demonstrated that phage-containing hydrogels significantly inhibited bacterial growth, with an OD of 0.3 compared to 1.1 for the controls. Hydrogels remained stable for four weeks. In vivo, phage-containing hydrogels reduced bacterial load and enhanced wound healing, as shown by improved epithelialization and tissue restoration.

Conclusion
Phage-containing hydrogels effectively treat wounds infected with E. faecalis-infected wounds, promoting wound healing through controlled phage release. These hydrogels can improve clinical outcomes in the treatment of infected wounds.
