Background: There is limited evidence on prevalence and risk factors for hepatitis C virus (HCV) infection among waste handlers in Sidama region, Ethiopia; however, this knowledge is necessary for effective prevention of HCV infection in the region. Methods: A cross-sectional study was conducted among randomly selected waste collectors from October 2021 to 30 July 2022 in different public hospitals of Sidama region of Ethiopia. Serum samples were collected from participants and screened for anti-HCV using rapid immunochromatography assay. Socio-demographic and risk factor information of waste handlers was gathered by pretested and well-structured questionnaires The generalized linear model (GLM) was conducted using R software, and P -value <0.05 was declared statistically significant. Results: From a total of 282 participating waste handlers, 16 (5.7%) (95% CI = 4.2–8.7) were infected with hepatitis C virus. Educational status of waste handlers was the significant demographic variable that was associated with hepatitis C virus (AOR = 0.055; 95% CI = 0.012–0.248; P = 0.000). More married waste handlers, 12 (75%), were HCV positive than unmarried, 4 (25%) and married waste handlers were 2.051 times (OR = 2.051, 95% CI = 0.644–6.527, P = 0.295) more prone to HCV infection, compared to unmarried, which was statistically insignificant. The GLM showed that exposure to blood (OR = 8.26; 95% CI = 1.878–10.925; P = 0.037), multiple sexual partners (AOR = 3.63; 95% CI = 2.751–5.808; P = 0.001), sharp injury (AOR = 2.77; 95% CI = 2.327–3.173; P = 0.036), not using personal protective equipment (AOR = 0.77; 95% CI = 0.032–0.937; P = 0.001), contact with jaundiced patient (AOR = 3.65; 95% CI = 1.093–4.368; P = 0.0048) and unprotected sex (AOR = 11.91; 95% CI = 5.847–16.854; P = 0.001) remained statistically significantly associated with HCV positivity. Conclusions: The study revealed that there was a high prevalence of hepatitis C virus infection among waste handlers in Sidama region, Ethiopia. This demonstrated that there is an urgent need to increase preventative efforts and strategic policy orientations to control the spread of the hepatitis C virus. [ABSTRACT FROM AUTHOR]

CLIMATE change & health ,CLIMATE change ,RESOURCE-limited settings ,GLOBAL burden of disease ,MEDICAL wastes - Abstract
Climate change is an emerging global health crisis, disproportionately affecting low- and middle-income countries (LMICs) where health outcomes are increasingly compromised by environmental stressors such as pollution, natural disasters, and human migration. With a focus on promoting health equity, Global Surgery advocates for expanding access to surgical care and enhancing health outcomes, particularly in resource-limited and disaster-affected areas like LMICs. The healthcare industry—and more specifically, surgical care—significantly contributes to the global carbon footprint, primarily through resource-intensive settings, i.e. operating rooms that generate greenhouse gases and substantial medical waste. Therefore, Global Surgery efforts aimed at improving surgical access through an increase in surgical volumes may inadvertently exacerbate health challenges for vulnerable populations by further contributing to environmental degradation. This predicament is particularly pronounced in LMICs, who already suffer from a disproportionate share of the global burden of disease, and where the demand for surgery is rising without corresponding resilient infrastructure. LMICs face a double jeopardy of health inequity coupled with climate vulnerability. As a movement positioned to improve health around the world, Global Surgery has an increasingly significant role in envisioning and ensuring a sustainable future. Global Surgery initiatives must prioritise sustainable infrastructure in both high-income countries (HICs) and LMICs, all while accounting for the unequal polluting contributions between HICs and LMICs and, consequently, moral responsibilities moving forward. Moreover, through targeting upstream causes of poor health at urban and perioperative levels, Global Surgery's interventions may help to reduce the global burden of disease—avoiding preventable surgeries and their carbon footprints from the outset. Altogether, Global Surgery and climate change are two matters of social justice whose solutions must synergistically centralise the health of both the planet and its most vulnerable people.

MEDICAL wastes , *COVID-19 pandemic , *WASTE management , *POLLUTION , *WASTE recycling , *MEDICAL waste disposal - Abstract
Medical waste is generated during the provision of care, protection, and preservation of human health, as well as through various services that involve contact with blood and bodily secretions. Procedures for the proper collection and disposal of waste, including medical waste, are a crucial component of public health preservation, as they prevent the direct or indirect transmission of infection. With the advancement of waste management systems, the management of medical waste has also evolved - from its point of origin to final disposal. Medical waste management includes the collection, transportation, processing, and disposal of the waste. The COVID-19 pandemic led to a significant increase in the production of medical and pharmaceutical waste, with four times more medical waste generated in 2020 than in 2019. According to data from the Register of Environmental Pollution (Croatian abbrev. ROO), 96 % of reported medical waste was classified under category 18 01 03* - waste that requires special collection and disposal procedures to prevent infection. The aim of this study was to point out the differences in the amounts of medical and pharmaceutical waste generated before and during the COVID-19 pandemic in Split-Dalmatia County, as well as the procedures for their disposal.

Background/Aims: Although gastrointestinal endoscopy (GIE) is a major contributor to the carbon footprint of national healthcare, the amount of medical waste generated by GIE procedures is not reported in South Korea. This study aimed to measure the amount of medical waste generated from GIE procedures in South Korea. Methods: We conducted a 5-day audit of medical waste generated during GIEs at seven hospitals. During the study period, medical waste in the endoscopy examination rooms was measured twice daily and documented as mass (kg). To calculate the mean mass of disposable waste generated during one esophagogastroduodenoscopy (EGD) and one colonoscopy, the mean mass of medical waste generated from seven examinations was calculated. The mean mass of medical waste generated during GIEs was calculated by dividing the total mass of medical waste generated by the number of GIE procedures. Results: Overall, 3,922 endoscopies were performed and 4,558 kg of waste was generated. The mean weight of medical waste generated per endoscopy was 1.34 kg. Each EGD and colonoscopy generated a mean of 0.24 kg and 0.43 kg of disposable waste, respectively. Applying the mean waste estimates from this study to annual GIE procedures performed in South Korea in 2022 showed that the total medical waste produced from GIE was 13,704,453 kg. In addition, the total masses of medical waste produced during EGD and colonoscopy procedures were 819,766 kg and 2,889,478 kg, respectively. Conclusions: Our quantitative measurement showed that a large amount of medical waste is generated from GIE procedures. However, further research is warranted to reduce medical waste generated during GIE, which is an urgent unmet need. [ABSTRACT FROM AUTHOR]

ABSTRACT: Background: For those who often use needles, such as nurses and laboratory professionals, needle stick injuries are a fact of life. Even if it's not medical waste, it can still happen if you touch garbage. Approximately 385,000 healthcare professionals stab themselves unintentionally each year. The likelihood of virus transmission after a skin puncture injury depends on the person who used the object in the first place, the quantity of blood involved, the type of needle or syringe in question, the length of time since it was last used, and the type of injury. Post-exposure prophylaxis should be taken into account. Objective: The objective of the study is to assess the impact of a structured educational campaign on nursing students' understanding of needle stick injuries and related post-exposure prophylaxis for HIV/AIDS. Methodology: Quasi experimental research design was used. Sixty nursing students B.Sc (N) and GNM (N) 1st year students were selected by using purposive sampling technique. The study was conducted at selected private nursing colleges at District Kangra, Himachal Pradesh. Results: In the pre-test knowledge score, (25%) nursing students had poor level of knowledge, (66.66%) nursing students had average level of knowledge, and (8.34%) nursing students had good level of knowledge. The post-test knowledge score (43.34%) nursing students had good level of knowledge, (56.66%) nursing students had average level of knowledge, and (0%) nursing students had poor level of knowledge The t value in the group was 9.50 which were highly significant at P < 0.05 level. Conclusion: Compared to video-assisted instruction, the lecture and demonstration technique is more successful. The fact that both teaching techniques contribute to improving understanding of HIV/AIDS and needle stick injuries. [ABSTRACT FROM AUTHOR]

Environmental protection issues have received widespread attention, making material recycling increasingly important. The upcycling of polysulfone (PSF) medical waste, recognized as a high-performance plastic with excellent mechanical properties, deserves promotion. While PSF is suitable for use as an orthopedic implant material, such as internal fixation, its osteogenesis capabilities must be enhanced. Mechanical stability, particularly over the long term, is a significant concern for bone implants in load-bearing applications. This study recycled PSF medical waste to create bone composites by incorporating osteogenic calcium silicate (CaSi) at three different contents: 10%, 20%, and 30%. We evaluated the phase, morphology, weight loss, and three-point bending strength of the PSF-based composites after they were soaked in dynamic simulated body fluid (SBF) at pH levels of 7.4 and 5.0 for up to 12 months. Human mesenchymal stem cells (hMSCs) were utilized to assess the osteogenic activity of these composites. Our findings revealed that, while the bending strength of PSF-based composites declined with prolonged exposure to SBF, the dissolution of CaSi particles led to a manageable weight loss of about 4% after 12 months, regardless of pH 7.4 or 5.0. Importantly, the incorporation of CaSi into the PSF matrix exhibited a positive effect on the attachment and proliferation of hMSCs. The levels of alkaline phosphatase (ALP) and calcium deposits directly correlated with the CaSi content, indicating superior osteogenic activity. Considering biostability and osteogenic ability, the 20% CaSi-PSF composite demonstrated promise as a candidate for load-bearing implant applications. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Methods Results Discussion Orthopedic implants may need to be removed for various reasons. There is little data on the appropriate handling of implants after their removal from patients. This study aimed to analyze how orthopedic surgeons handle removed implants and their underlying philosophies, using data collected from a survey.This study, conducted between May 2024 and June 2024, utilized an online survey targeting orthopedic surgeons and residents in Turkey to investigate practices and views regarding removed implants. A total of 205 participants completed an 11‐question online survey via Google Forms. The survey covered hospital types, professional experience, protocols for handling removed implants, practices for archiving and disposing of implants, and perspectives on current practices and future direction.Participants' professional experience varied widely. None of the participants followed a specific protocol for managing removed implants. Opinions on giving implants to patients were diverse: 17.1% would never give the implant to the patient, 32.2% would comply with the patient's request, and 50.7% had no definitive approach. A minority (2.9%) systematically archived implants, while others archived selectively or disposed of them as medical waste. The primary motivations for archiving included medicolegal protection (21%) and professional curiosity (75.2%). Only 2.9% had experience with legal requests for removed implants, and 80% supported establishing regulations for handling removed implants.Orthopedic surgeons' legal and ethical perceptions regarding removed implants, as well as their preference of handling, vary widely. Establishing a standardized approach can reduce this variability in practice and ensure uniformity in healthcare. [ABSTRACT FROM AUTHOR]

Background: Lung adenocarcinoma patients are often found to have developed bone metastases at the time of initial diagnosis. With the continuous development of technology, we have successfully entered the era of immunotherapy. This study aimed to determine the efficacy of immunotherapy in lung adenocarcinoma patients with bone metastases (LABM) through a multicenter retrospective analysis and to develop a novel tool to identify the population that could benefit most from immunotherapy. Methods: To assess the impact of immunotherapy on LABM in terms of overall survival, we used analytical tools such as Kaplan-Meier analysis, Log-ranch test, and propensity score matching (PSM) method. A predictive model for constructing overall survival was constructed using Cox regression modeling. Based on this, we developed a risk classification system depicting Kaplan-Meier curves for subgroup analysis to determine the optimal beneficiary population for immunotherapy in different risk subgroups. Results: A total of 20073 eligible patients were enrolled in this study, of whom 8010 did not receive immunotherapy, while 12063 patients received immunotherapy. After 1:1 PSM, 15848 patients were successfully coordinated, yielding a balanced cohort. Kaplan-Meier survival curves showed significantly enhanced overall survival (P < 0.001) in patients who received immunotherapy compared to those who did not. The results of Cox regression analyses showed that age, race, sex, primary site, immunotherapy, surgery, chemotherapy, brain metastasis, liver metastasis, lung metastasis, and marital status were independent prognostic factors. The area under the curve for all three cohorts was close to 0.7, indicating that the model was well-discriminating. The calibration curves further proved that the model had a high predictive accuracy. Decision curve analysis demonstrated that the model could achieve a high net clinical benefit. The risk classification system developed based on the model successfully screened the best beneficiary population for immunotherapy. Conclusion: This study provides convincing evidence that immunotherapy provides a significant survival advantage for LABM. Secondly, the clinical tools constructed in this study can help clinicians identify the optimal population to benefit from immunotherapy in LABM, thus enabling precise treatment and avoiding the waste of medical resources and over-treatment of patients.

Background: The aim of this study is to establish a nomogram that can predict the risk factors for delayed bleeding after endoscopic submucosal dissection (ESD). This model can be used to assess the probability of delayed bleeding before ESD surgery, thereby avoiding wasting medical resources and improving patient satisfaction. Methods: This was a retrospective study in which all patients underwent ESD surgery for colorectal tumors between August 2021 and February 2024. Patient demographics and surgical characteristics were collected. All patients were randomly divided into a training set and a testing set. Univariate and multivariate regression analyses of the training set revealed the independent risk factors for delayed bleeding after ESD. These independent risk factors were used to construct a nomogram model. This model was validated using internal validation methods such as the C-index, calibration curve, and decision curve analysis. Results: This study included 587 patients. The occurrence rate of delayed bleeding after ESD in the training set was 8.98%. Multivariate regression analysis revealed that the location of the lesion in the rectum, a large lesion, and a prolonged surgery time were independent risk factors for delayed bleeding after ESD. The C-index for this model was 0.89, and validation of this nomogram model demonstrated good consistency between the predicted and actual values. Conclusion: Multivariate regression analysis revealed the independent risk factors for delayed bleeding after ESD, and a nomogram with a relatively consistent accuracy was established. The clinical application of this model can reduce the incidence of delayed bleeding and therefore improve patient healing. [ABSTRACT FROM AUTHOR]

The study aims to synthesize Titanium Dioxide (TiO2) nanoparticles using expired disprin and paracetamol, exploring an innovative approach to curb the hazards posed by discarded expired medicines thereby reducing drug pollution and improving ecological footprint. The sol-gel method was employed to synthesize TiO2 nanoparticles using expired disprin and paracetamol. Various characterization techniques, such as X-Ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS), Field Emission Scanning Electron Microscopy (FESEM), Selected Area Electron Diffraction (SAED), and Vibrating Sample Magnetometer (VSM), were used to analyse the synthesized nanoparticles. The XRD and EDS analyses confirmed the formation of TiO2 nanoparticles. The nanoparticles synthesized from both paracetamol and disprin showed a dominant anatase phase with stray peaks of rutile and brookite phases. SAED of paracetamol-derived nanoparticles showed a highly crystalline structure. FESEM confirmed the synthesis of uniformly distributed spherical nanoparticles with size range between 5-20 nm. The size of nanoparticles estimated from both XRD and FESEM appear to be in good agreement. VSM confirmed the diamagnetic nature of both paracetamol and disprin-derived nanoparticles. The study demonstrates that synthesizing TiO2 nanoparticles using expired pharmaceuticals can be a promising approach to mitigate the environmental hazards posed by discarded expired medicines. This novel method has the potential to revolutionize the synthesis of nanoparticles and contribute to a more sustainable future. [ABSTRACT FROM AUTHOR]

The purpose of this study was to identify and explore certified registered nurse anesthetists' (CRNA) knowledge, current practices, and barriers to proper sharps waste disposal practices in the operating room. Approximately 100 CRNAs who practice anesthesia in the Mid-Atlantic region at 10 different hospitals were given an electronic survey. Forty CRNAs completed the 15-question de novo quantitative descriptive survey. The survey was created by three researchers and five experts in the field to ensure validity. Data were analyzed using the chisquared test and the Mann-Whitney U test. Thirty-seven percent of respondents reported placing unbroken vials, and 46.4% reported placing empty plastic syringes with needles still attached in sharps containers. Most survey respondents (73.7%) agreed that they had inadequate information creating a knowledge deficit on the proper disposal of sharps and that additional teaching material would be helpful.

Pseudomonas aeruginosa is a pathogenic bacterium widely distributed in the environment, with increasing concerns about multidrug-resistant (MDR) strains in riverine systems. In this study, we assessed the antibiotic resistance of 50 P. aeruginosa isolates from surface water samples collected at seven distinct sites along the Buriganga River. Antibiotic sensitivity was tested using the Kirby–Bauer Disk Diffusion method. The results showed widespread antibiotic resistance, with 88% of isolates resistant to cefotaxime and tetracycline, followed by 48% resistance to cefepime and 24% to ciprofloxacin. Conversely, most isolates were susceptible to penicillin, aminoglycosides, carbapenems, and fluoroquinolone-class antibiotics, with sensitivity rates of 100, 98, 92, 94, and 96%, respectively. Thirteen isolates (26%) were classified as MDR, predominantly from point-source pollution sites such as industries, medical waste, and municipal waste discharges. Notably, 4% of isolates exhibited resistance to both imipenem and meropenem, raising concerns about the spread of carbapenem-resistant P. aeruginosa in the river. This study highlights the contamination of river water with antibiotic-resistant P. aeruginosa and its potential transmission through aquatic systems. Proper waste management and treatment are critical to controlling the spread of MDR isolates, which pose risks to both public health and the environment. [ABSTRACT FROM AUTHOR]

Value-based healthcare payment models are an alternative insurance payment system that compensates healthcare providers based on their patients' outcomes rather than the individual services healthcare workers provide. This shift from the current fee-for-service model that predominates our medical system has received renewed popularity and attention within organized medicine such as the American Medical Association. Advocates believe that this new payment model will address many of the unsolved issues in healthcare such as medical waste and unsustainable healthcare costs. In practice, however, this model is plagued with a myriad of unresolved issues of its own. In this commentary, we outline these issues and suggest that the intentions of those advocating for value-based payment models are either misguided or disingenuous. We then offer solutions that preserve our current fee-for-service model while making necessary changes that will benefit both physicians and patients nationwide. [ABSTRACT FROM AUTHOR]

Solid waste incineration (SWI) can release numerous air pollutants although the geographic reach of emissions is not routinely monitored. While many studies use moss and lichens for biomonitoring trace elements, including around SWIs, few investigate the complex, multi-element footprint expected from SWI emissions. This study develops using native moss as a screening tool for SWI while also informing community concerns about an aging incinerator in rural Oregon, USA. Trained community volunteers helped collect 36 composite samples of epiphytic moss (Orthotrichum s.l.) along a 32-km transect from the SWI. We used ICP-MS to measure 40 elements in moss, including 14 rare earth elements (REEs) previously unexplored for SWI. We compared the elemental signatures of samples with an emissions profile for SWI and modeled relationships between element concentrations and distance from the facility using nonparametric regression. The chemical signatures in moss pointed to SWI as a source, potentially through both stack and fugitive dust emissions. The strongest models described farther-dispersing elements, including mercury and cadmium (xR
2 = 0.65 and 0.62, respectively), and suggested most deposition occurs within 5 to 10 km of the facility. Elements often associated with soil and dust, like arsenic and chromium, exhibited localized peaks within 0.2 km of the incinerator (xR2 = 0.14–0.3). Three novel elements—cesium and REEs europium and gadolinium—also showed promise as atmospheric tracers for SWI. Gadolinium, a contrast reagent for MRIs, could reflect medical waste incineration by the facility. We include additional analysis and discussion to help stakeholders use results effectively.

Healthcare waste (HCW) affects the sustainable development of the environment greatly. The choice of medical waste treatment methods has become a significant concern for public health and safety due to the rapid surge in the volume and diversity of medical waste. As an important aspect of environmental risk assessment (ERA), HCW risk assessment plays a crucial role in environmental protection to develop sustainability strategies. Failure Mode and Effects Analysis (FMEA) has been extensively utilized in HCW risk assessment in the past few decades. In this paper, we aimed to address the limitations of traditional FMEA while incorporating the benefits of diverse FMEA methods and employ a novel ensemble learning technique-based FMEA method to perform risk assessment of HCW. A real-world case of HCW risk assessment is investigated for the verification of the performance and effectiveness of the ensemble learning technique-based Environment FMEA (EFMEA). Result of the case study shows that this ensemble learning technique-based EFMEA can provide a more reliable assessment result for HCW risk management. [ABSTRACT FROM AUTHOR]

Background: The significant increase in home healthcare (HHC) driven by technological advancements, an ageing population, and heightened disease outbreaks—especially evident during the COVID-19 pandemic—has created an urgent need for improved medical waste management. Methods: This paper presents the development of a decision support system with a web-based interface designed for efficient medical waste collection in the HHC sector. Results: The system utilises Flask for backend operations, with HTML and CSS for the user interface, and manages data using JSON files. Its flexible design supports real-time adjustments for various vehicle types and changing waste production locations. It incorporates dynamic routing by employing two sophisticated metaheuristic algorithms: the Strength Pareto Evolutionary Algorithm (SPEA-2) and the Non-Dominated Sorting Genetic Algorithm (NSGA-II). This setup supports different dataset sizes and vehicle fleets, including Internal Combustion Engine (ICE) vehicles and Electric Vehicles (EVs). Conclusions: The automation reduces uncertainties in waste collection by minimising human intervention. The system is built to be easily adaptable for other sectors with minor modifications and can be expanded to test various scenarios with new selectable parameters. [ABSTRACT FROM AUTHOR]

Background: Acute care of patients in the emergency department (ED) can be very challenging when patients attend EDs without their important medical information. This is especially problematic for multimorbid patients under polypharmacy. The aim of this study was to assess systematically the frequency and clinical relevance of incomplete medical data upon ED admission. Methods: The study was conducted in the neurological ED of a German tertiary hospital. The availability and accuracy of medical data of all neurological patients in the ED were assessed upon arrival. Treating ED physicians were asked about the acute care of the patients to clarify whether missing data resulted in delays or complications in the emergency treatment. Additionally, doctors responsible for the inpatient care of patients who were admitted to a ward via the ED were questioned about the course of the inpatient stay to monitor how initially missing data might have influenced the hospital stay. Results: Medical data of 27% of the 272 included patients were missing or incomplete upon admission in the ED. The ED physicians had to make additional phone calls to gather information in 57% of these cases (vs. 22% in patients with complete data, p < 0.0001). Delays between 5 and 240 min were documented due to initially missing data. Unnecessary diagnostic procedures (e.g., lumbar puncture) were performed in 5% of these patients, thus compromising patient safety. Even the inpatient stay was complicated by initially missing data, as doctors still had to spend time (between 10 and 180 min) to gain relevant information. Retrospectively, 5% of hospitalizations could have been avoided if all medical information had been available upon ED admission. Conclusions: Missing medical data caused complications and delays in acute as well as inpatient care of patients admitted to the neurological ED. This compromised patient safety and led to a waste of medical resources and valuable time of the responsible medical team. Therefore, a comprehensive, digital data management system is urgently needed to improve patient safety and facilitate efficient patient care in the ED and beyond. [ABSTRACT FROM AUTHOR]

Introduction: The disposal of regulated medical waste (RMW) in the healthcare setting can be both costly and environmentally harmful. Prior studies have found large amounts of waste disposed of in RMW containers are inappropriately placed. Few studies to date have investigated the efficacy of waste reduction practices in the dermatology setting. Methods: This study aims to evaluate the effectiveness of a practice-wide intervention in reducing RMW in the outpatient dermatology setting. By performing daily waste audits and two concurrent educational interventions, the amount of RMW produced and percent of appropriately placed RMW will be measured. Further analysis will occur by comparing pre-intervention values to post-intervention values. Results: The percentage of waste properly placed in RMW containers prior to any intervention was 11%. Following both educational interventions, the percentage of waste properly placed in RMW containers increased by 56.1% (CI 43.7–68.5%) and the percentage of total waste produced that was identified and disposed of as RMW decreased by 6.0% (95% CI 1.2–10.8%). Conclusion: Our study provides practical data for dermatology providers to make small changes which can result in significant reductions of regulated medical waste, potentially providing benefits to the environment and cost-savings.

Polysulfone (PSF) medical waste can be effectively repurposed due to its excellent mechanical properties. Due to the increasing need for load-bearing bone implants, it is crucial to prioritize the development of biocompatible polymer–matrix composites. Calcium silicate (CaSi), known for its osteogenesis and antibacterial properties, is widely used in medical applications. In this study, recycled PSF plastics in fiber or nanoparticle forms and commercial PSF products were used to create PSF-based composites filled with three different amounts (10, 20, and 30 vol%) of CaSi. The green compact was heat-treated at various temperatures. Experimental results showed that the mechanical interlocking of the PSF matrix and CaSi filler occurred due to the liquefaction of PSF fibers or nanoparticles during heat treatment. When the composite contained 20% CaSi, the obtained three-point bending strength exceeded 60 MPa, falling within the reported strength of compact bone. There was a concurrent improvement in the biocompatibility and antibacterial activity of the PSF-based composites with the increasing amount of CaSi. Considering their mechanical properties and antibacterial activity, the 20% CaSi-containing PSF-based composites treated at 240 °C emerged as a promising candidate for bone implant applications. This study demonstrated the feasibility of upcycling medical waste such as PSF as a matrix, opening doors for its potential usage in the medical field. [ABSTRACT FROM AUTHOR]

Climate change poses an increasing threat to human health, with well-documented impacts on dermatologic conditions. However, the U.S. healthcare sector is paradoxically a significant contributor to climate change--worsening greenhouse gas emissions. To address this negative externality, calls to action to decarbonize healthcare delivery have spurred research and initiatives around improving the environmental sustainability of medicine. Published sustainability recommendations for dermatologic practices have addressed themes such as renewable energy, single-use disposable materials, regulated medical waste, and clinician advocacy. Our current commentary provides an analysis of the potential of existing recommendations and outlines additional, novel, and actionable interventions. We highlight recently released decarbonization resources and regulatory changes. We emphasize the importance of reassessing procedure kits, minimizing medication waste, and implementing green procurement policies. We also address nuances in promoting environmentally-conscious transit, maximizing the efficient use of technology, supporting alternatives to single-use items, leveraging resources for patient education, assessing appropriate use of carbon credits, and bolstering community climate resilience.

Proper hospital waste management poses important concerns due to the risk capacity of hospital waste to health and the environment. Healthcare management approaches have changed in recent years, motivated by the desire to minimize the environmental impact. The review aims to examine the current HCW and considers the local challenges associated with establishing a circular economy (CE) to improve hospital waste management regarding training along Plan, Do, Check, and Act (PDCA). The study found that mean medical and general waste segregation rates in public hospitals were 50.15 and 49.85, respectively. On average, 3.6 kg of waste was generated per bed per day. Analysis revealed a significant correlation between total waste and infectious waste with the number of occupied beds in the hospital (p < 0.05). Updating national laws by the CE approach is necessary. Our insights into circular hospital waste urge establishing a green management team, new training methods, and continuous supervision. Using PDCA to enhance waste segregation, training, and other aspects of hospital waste management is vital. [ABSTRACT FROM AUTHOR]

Background Pisum sativum: (PS) is a universal legume plant utilized for both human and animal consumption, particularly its seeds, known as green peas. The processing of PS in food industries and households produces a significant amount of waste that needs to be valorized. Methods: In this study, the metabolite profiles of the 70% ethanolic extracts of PS wastes, namely peels (PSP) and a combination of leaves and stems (PSLS), were investigated by liquid chromatography-electrospray ionization-quadrupole time-of-flight tandem mass spectrometry (LC-ESI-QTOF-MS/MS) followed by molecular networking. Results: Different classes of metabolites were identified, being flavonoids and their derivatives, along with phenolic acids, the most abundant categories. Additionally, a comprehensive network pharmacology strategy was applied to elucidate potentially active metabolites, key targets, and the pathways involved in cytotoxic activity against breast cancer. This cytotoxic activity was investigated in MCF-7 and MCF-10a cell lines. Results revealed that PSLS extract exhibited a potent cytotoxic activity with a good selectivity index (IC
50 = 17.67 and selectivity index of 3.51), compared to the reference drug doxorubicin (IC50 = 2.69 µg/mL and selectivity index of 5.28). Whereas PSP extract appeared to be less potent and selective (IC50 = 32.92 µg/mL and selectivity index of 1.62). A similar performance was also observed for several polyphenolics isolated from the PSLS extract, including methyl cis p-coumarate, trans p-coumaric acid, and liquiritigenin/ 7-methyl liquiritigenin mixture. Methyl cis p-coumarate showed the most potent cytotoxic activity against MCF-7 cell line and the highest selectivity (IC50 = 1.18 µg/mL (6.91 µM) and selectivity index of 27.42). The network pharmacology study revealed that the isolated compounds could interact with several breast cancer-associated protein targets including carbonic anhydrases 1, 2, 4, 9, and 12, as well as aldo-keto reductase family 1 member B1, adenosine A3 receptor, protein tyrosine phosphatase non-receptor type 1, and estrogen receptor 2. Conclusion: The uncovered therapeutic potential of PSLS and its metabolite constituents pave the way for an efficient and mindful PS waste valorization, calling for further in-vitro and in-vivo research.

The COVID-19 pandemic has led to a surge in medical waste generation, posing hazards to both the environment and global health. The impacts of the COVID-19 pandemic's medical waste hazard may persist long after the pandemic itself subsides. Improper disposal of medical waste can contaminate environment, posing risks to ecosystems and public health. Discarded medical rubber gloves, for example, can become a source of infection, improper disposal of these gloves can escalate the spread of infectious diseases and increase the risk of transmission of the virus to the general public. This study proposes an innovative and sustainable method to reinforce cement mortar by adding recycled glove rubber as an additive to cement mortar to increase its resistance to impact loads. This study conducted uniaxial compression tests, separating hopkinson pressure bar (SHPB) experiments and SEM observations to evaluate the quasi-static compressive strength and dynamic stress of recycled rubber fiber mortar (RRFM) with varying recycled rubber fiber (RRF) contents (0, 1%, 2%, 3%). Strain curves, dynamic increase factor (DIF), energy absorption rules, failure modes, and microstructure of RRFM mixtures. The experimental results demonstrate that with the addition of RRF, the dynamic stress-strain curve flattens and the peak strain gradually increases. The RRFM sample shows stronger toughness. In comparison to regular cement mortar (NM), RRFM has a higher DIF and specific absorbed energy, a faster increase in dynamic compressive strength, and the ability to absorb more energy per unit volume. Under the same impact load, RRFM has fewer and smaller cracks than NM. Scanning electron microscopy (SEM) testing also observed that RRF formed a strong connection pattern with the cement mortar matrix. [ABSTRACT FROM AUTHOR]

Medical waste management is a crucial issue due to its potential health risks to humans and harm to the environment. The World Health Organization (WHO) advises separating medical waste into seven groups based on its type. However, despite the implementation of color-coded bin bags, cases of missegregation still occur frequently, leading to injuries and spreading diseases. Infectious waste such as sharps, human tissue, and body parts are often found mixed in waste bins, posing a severe threat to waste employees. To address this issue, this paper proposes exploring the potential of digitalization in waste segregation. The literature on current segregation methods and technology applications is analysed and compared, and a framework for utilizing barcode tagging and scanning to ensure waste is correctly categorized is presented. The barcodes and scanner will be connected through a monitoring system, which can notify waste generators and collectors of misplacing or mixed waste. This digitalization system is expected to serve as a monitoring agent for segregating waste before it is collected from any health facilities. Additionally, the exchanged data from waste generator bins can inform collectors and other waste stakeholders about the waste's condition, potentially opening up opportunities for recycling companies to purchase used plastics or metals from hospital wastes. By implementing digitalization in medical waste management, waste segregation can improve, reduce the spread of diseases and injuries, and promote the recycling of hospital waste materials.

Taiwan has been an active participant in waste recycling for a long period of time due to the need for resource sustainability. The country believes it can one day eventually achieve the goal of zero waste through the effective use of strategies such as source reduction, resource recovery, reuse, and recycling. Despite Taiwan's long‐standing commitment to waste recycling for purposes of resource sustainability, achieving the goal of zero waste remains an immense challenge. Therefore, putting into effect the previously mentioned strategies will obviously be necessary in order to realize this goal. However, the effective implementation of these strategies requires both comprehensive planning and coordination, particularly in large medical institutions. Here, we have aimed to promote waste reduction throughout the entire hospital system in Taiwan using 3 strategies: (1) standardizing the colors of garbage bags, marking patterns of waste, and reviewing and establishing an internal audit mechanism on a regular basis; (2) the systematic monitoring of individual departments with regard to on waste consumption, brands, and materials while linking departments to the procurement source management team. In addition, any related hardware has been upgraded, precisely controlled, and automatically uploaded to the cloud system for an improved intelligent management system. In addition, the Department of Nutrition has adjusted the handling of ingredients and consumption patterns of hospital employees in order to reduce food waste; and (3) with regard to the disposal of medical waste, medical centers will be consolidating and advancing the knowledge and ability of all hospital personnel through education and training programs established for them. After the implementation of this program to promote awareness, the ratio of biological waste percentage in regard to total hospital waste dropped from 37.3% in 2018 to 33.6% in 2022, with a 49% decrease being seen in food waste, and a 99.32% increase being realized in green designated procurement items. Such an efficient management of medical waste has no doubt been extremely beneficial to the hospital. [ABSTRACT FROM AUTHOR]

The escalating generation of household medical waste, a byproduct of industrialization and global population growth, has rendered its transportation and logistics management a critical societal concern. This study delves into the optimization of routes for vehicles within the household medical waste logistics network, a response to the imperative of managing this waste effectively. The potential for environmental and public health hazards due to improper waste disposal is acknowledged, prompting the incorporation of contamination risk, influenced by transport duration, waste volume, and wind velocity, into the analysis. To enhance the realism of the simulation, traffic congestion is integrated into the vehicle speed function, reflecting the urban roads' variability. Subsequently, a Bi-objective mixed-integer programming model is formulated to concurrently minimize total operational costs and environmental pollution risks. The complexity inherent in the optimization problem has motivated the development of the Adaptive Hybrid Artificial Fish Swarming Algorithm with Non-Dominated Sorting (AH-NSAFSA). This algorithm employs a sophisticated approach, amalgamating congestion distance and individual ranking to discern optimal solutions from the population. It incorporates a decay function to facilitate an adaptive iterative process, enhancing the algorithm's convergence properties. Furthermore, it leverages the concept of crossover-induced elimination to preserve the genetic diversity and overall robustness of the solution set. The empirical evaluation of AH-NSAFSA is conducted using a test set derived from the Solomon dataset, demonstrating the algorithm's capability to generate feasible non-dominated solutions for household medical waste recycling path planning. Comparative analysis with the Non-dominated Sorted Artificial Fish Swarm Algorithm (NSAFSA) and Non-dominated Sorted Genetic Algorithm II (NSGA-II) across metrics such as MID, SM, NOS, and CT reveals that AH-NSAFSA excels in MID, SM, and NOS, and surpasses NSAFSA in CT, albeit slightly underperforming relative to NSGA-II. The study's holistic approach to waste recycling route planning, which integrates cost-effectiveness with pollution risk and traffic congestion considerations, offers substantial support for enterprises in formulating sustainable green development strategies. AH-NSAFSA offers an eco-efficient, holistic approach to medical waste recycling, advancing sustainable management practices. [ABSTRACT FROM AUTHOR]

After attaining menarche adolescents, due to shyness and fear, often refuse to seek medical treatment. Simultaneously they began to face menstrual disorders. The present review aimed to estimate the overall menstrual disorders and associated factors among adolescent girls in rural and tribal areas in India as well as to summarize the most recent research findings on the pooled prevalence of menstrual disorders. The study design was developed applying the PRISMA checklist-2020. The whole protocol was registered on PROSPERO (Registration ID: CRD42024385046). Articles (English language) related to menstrual irregularities among 10 to 19-year-old adolescent girls in India were collected based on inclusion and exclusion criteria from 2000 to 2023 followed by selected keywords. The quality assessment of the present study was evaluated using the CASP (Critical Appraisal Skills Programme) checklist. Meta-analysis was conducted by using MedCalc software version 22.0. Publication bias was checked using Egger's test. A total of 61 studies (47 from rural and 14 from tribal areas) in India have been evaluated. The random effect model showed an overall prevalence of dysmenorrhea, irregular menstruation, PMS, oligomenorrhea, polymenorrhea and menorrhagia in both areas was 54.96% (95% CI: 47.93 to 61.85), 26.21% (95% CI: 20.73 to 32.09), 47.49% (95% CI: 31.44 to 63.81), 13.88% (95% CI: 8.98 to 19.65),7.85% (95% CI: 2.30 to 16.31), 16.83% (95% CI: 10.04 to 24.96) respectively. Among these, dysmenorrhea, irregular menstruation, and PMS were found to be the most predominant in both areas. Lack of physical activities, dietary habits, BMI, socioeconomic factors, and socio-cultural taboos were found to have a strong association with menstrual irregularities. Prior and after attaining menarche, proper guidance on every aspect of menstruation should be urgently arranged in schools and at home to get rid of fear and anxiety, so that adolescent girls can cope with menstrual-related issues. Health camps should be organized in both areas to allow an easy access. [ABSTRACT FROM AUTHOR]

Aims and Objectives: To evaluate the drug wastage and additional costs (in INR) resulting from leftover or unused drugs due to limited vial strength options, and to propose vial size recommendations to pharmaceutical companies tailored to Indian requirements. Material and Methods: A total of 500 adult patients attending daycare oncology were prospectively evaluated. Mean, median, mode and left over or unused drug dose for each chemotherapy drugs were calculated. The economic loss estimation was done considering the unit cost for the drug. Result: The overall drug wastage for 500 prescriptions was 57,836 mg, accounting for 8.67% of the total prescribed dose. This resulted in an economic loss of 1,02,562 INR, which is 6.26% of the total cost. The highest proportions of drug wastage were observed for vincristine (28.72%), etoposide (23.20%), bleomycin (18.5%), pemetrexed (17.10%), nab-paclitaxel (16.37%), vinblastine (14.70%), Adriamycin (11.76%), and carboplatin (11.36%). The maximum economic loss was attributed to carboplatin (19.66%), nab-paclitaxel (17%), etoposide (14.5%), oxaliplatin (9.45%), and pemetrexed (7%). In combination chemotherapy regimens, gemcitabine-cisplatin-nab-paclitaxel (18.52%), pemetrexed-carboplatin (11.82%), and carboplatin-etoposide (8.97%) were responsible for the highest monetary losses due to drug wastage. Conclusion: Drug wastage due to oversized chemotherapy vials imposes significant financial and environmental burdens. We recommend offering additional vial size options for carboplatin, etoposide, gemcitabine, nab-paclitaxel, irinotecan, vincristine, and 5-FU. We hope this will reduce drug wastage to below 1-2%.

Traditional healthcare delivery models face mounting pressure from rising costs, increasing demand, and a growing environmental footprint. Hospital at Home (HaH) has been proposed as a potential solution, offering care at home through in-person, virtual, or hybrid approaches. Despite focus on expanding HaH provision and capacity, research has primarily explored patient care outcomes, patient satisfaction economic costs with a key gap in its environmental impact. By reducing this evidence gap, HaH may be better placed as a positive enabler in delivering healthier planet and population. This article explores the environmental opportunities and challenges associated with HaH compared to traditional hospital care and reinforces the case for further research to comprehensively quantify the environmental impact including any co-benefits. Our aim for this article is to spark conversation, and begin to help prioritise future research and analysis. [ABSTRACT FROM AUTHOR]

Military burn pits, used for waste disposal in combat zones, involve the open-air burning of waste materials, including plastics, metals, chemicals, and medical waste. The pits release a complex mixture of occupational toxic substances, including particulate matter (PM), volatile organic compounds (VOCs), heavy metals, dioxins, and polycyclic aromatic hydrocarbons (PAHs). Air pollution significantly impacts brain health through mechanisms involving neuroinflammation. Pollutants penetrate the respiratory system, enter the bloodstream, and cross the blood–brain barrier (BBB), triggering inflammatory responses in the central nervous system (CNS). Chronic environmental exposures result in sustained inflammation, oxidative stress, and neuronal damage, contributing to neurodegenerative diseases and cognitive impairment. Veterans exposed to burn pit toxins are particularly at risk, reporting higher rates of respiratory issues, neurological conditions, cognitive impairments, and mental health disorders. Studies demonstrate that Veterans exposed to these toxins have higher rates of neuroinflammatory markers, accelerated cognitive decline, and increased risks of neurodegenerative diseases. This narrative review synthesizes the research linking airborne pollutants such as PM, VOCs, and heavy metals to neuroinflammatory processes and cognitive effects. There is a need for targeted interventions to mitigate the harmful and escalating effects of environmental air pollution exposures on the CNS, improving public health outcomes for vulnerable populations, especially for Veterans exposed to military burn pit toxins.

Traditional waste incineration generates a large amount of exhaust gas, resulting in adverse environmental impacts. Therefore, we developed an organic and intelligent photochemical processing system that utilizes high-energy lasers for incineration, thereby reducing the production of exhaust gas. A large-scale laser machine was set up, incorporating low-cost 2D Light Detection and Ranging (LiDAR) technology for system sensing, which performs angle range and threshold filtering, as well as multispectral laser allocation, integrated with the laser ablation machine system. After testing, the error was <5 mm (<8%), achieving precise object scanning and ranging and solving the problem of manual laser positioning. Experimental results showed that CO
2 lasers can effectively process organic materials and medical waste of different sizes. This innovative research will have profound implications for the future development of environmental protection and incineration technologies. In the future, it has widespread application prospects in areas such as pet waste disposal and medical waste treatment. [ABSTRACT FROM AUTHOR]- Published

This research explored the life cycle analysis and environmental cost-benefit assessment of converting ash waste from hospital medical waste incineration into environmentally safe paving block raw materials. The growing concerns about medical waste disposal and its environmental impact necessitate innovative solutions for sustainable waste management. This research aimed to evaluate the feasibility and environmental implications of reusing hospital waste into raw materials for paving block mixtures. This research, a comprehensive life cycle analysis, examined the environmental impacts of medical waste collection for the production and use of paving blocks. Additionally, we conducted an environmental cost-benefit assessment to ascertain the economic feasibility and potential environmental impact forecasts of this recycling approach. The research results show that converting hospital medical waste ash into mixed raw materials for paving blocks not only immobilizes heavy metals but also provides a sustainable alternative for non-building materials. These findings highlight the potential for significant environmental and economic benefits, making this approach a promising strategy for waste management and sustainable construction practices. The cost of preventing environmental damage (eco-cost) in the process of converting ash from the incineration of medical waste into a mixture of raw materials for paving blocks is IDR 600,180.9 per cycle.

The use of plastic products or components in medical equipment and supplies results in challenges in terms of environmental sustainability and waste management for disposable, non-recyclable, and non-biodegradable materials. Medical plastic waste includes items ranging from syringes, tubing, intravenous (IV) bags, packaging, and more. Developing biodegradable replacements to petroleum-based plastics in medical equipment has not yet become an urgent priority, but it is an important endeavor. Examining alternatives involves several key themes, including material selection, testing, validation, and regulatory approval. To date, research includes studies on biodegradable polymers, composite materials, surface modifications, bacterial cellulose, three-dimensional (3D) printing with biodegradable materials, clinical trials and testing, collaboration with industry, regulatory considerations, sustainable packaging for medical devices, and life cycle analysis. The incorporation of bio-based and biodegradable plastics in the healthcare industry holds immense potential for reducing the environmental impact of medical plastic waste. The literature suggests that researchers and industry professionals are actively working towards finding sustainable alternatives that meet the stringent requirements of the medical industry. This paper reviews the efforts made so far to develop biodegradable and sustainable alternatives to plastic in medical equipment using a meta-analysis of resources, which include relevant papers published in English until June 2024. A total of 116 documents were found and screened by three reviewers for relevance. The literature reviewed indicated that various medical uses require plastics due to their unique properties, such as having strength and flexibility; being lightweight; and being able to prevent bacterial contamination. Among the alternatives, polycaprolactone (PCL), polylactic-co-glycolic acid (PLGA), starch-based acid, and polybutyric acid (PBS) have demonstrated favourable outcomes in terms of biocompatibility, safety, and efficacy. Additionally, a set of approaches to overcome these barriers and strategies is discussed alongside potential future solutions. This review aims to catalyze discussions and actions toward a more environmentally sustainable future in the medical industry by providing a comprehensive analysis of the current state, challenges, and prospects of this domain.

Wearing face masks is the best way to stop the spread of respiratory infections. However, if masks are not sterilized, changing them too frequently can actually increase the risk of cross‐contamination. Herein, the construction of an antipathogen photocatalytic mask with carbon vacancy‐modified carbon nitride nanosheets (g‐C3N4‐VC Ns) coated on the non‐woven fabrics of the out layer of the mask, offering effective and long‐term protection against damaging pathogens when exposed to light is reported. The introduced carbon vacancies are found capable of creating energy‐disordered sites and inducing energetic electric force to overcome the Coulomb interactions between electron‐hole pairs, thus promoting the electron‐hole separation to achieve a high generation of reactive oxygen species (ROS). Thanks to its high activity in generating ROS upon exposure to light, the as‐prepared photocatalytic mask shows high pathogen sterilization performance. This, in turn, prolongs the mask's protective lifetime, decreases the need for regular replacement, and decreases medical waste production. The work demonstrated here opens new viewpoints in designing pathogens biocidal protective devices for health protection, offering significant promise in specific environment self‐protection.

Operating rooms (ORs) use energy-intensive equipment such as anesthesia gas machines, patient monitors, and lights. They are major contributors to an institution's carbon footprint; yet ORs are unoccupied 40% of the time. Implementing an initiative to power down electrical devices can reduce energy consumption, equipment failure, and financial outlay. This quality improvement project developed and implemented a power down initiative for anesthesia staff to use in ORs. The initiative included turning off anesthesia gas machines, patient monitors, auxiliary oxygen delivery, and room lights at the end of scheduled cases in ORs that were not used for emergencies. Convenience audits were conducted. Pre- and postimplementation compliance outcomes showed that there was an increase in powering down the anesthesia gas machine, patient monitor, auxiliary oxygen, and room lights. Powering down unnecessary equipment at this facility has the potential to save approximately $50,000 and prevent the emission of over 80 metric tons of CO2 per year. Other facilities can implement a similar quality improvement project aimed at fiscal and ecological conservation. [ABSTRACT FROM AUTHOR]

Addressing the pollution problems caused by improper disposal of effluents and wastes from pharmaceutical companies and medical facilities are important for the safety of humans and animals. This work highlights the challenges and developments in medical and pharmaceutical waste management practices across the world as well as their potential for bio-energy production. It involves the study of these waste properties, their impacts on the ecosystem and treatment or recycling methods. Various studies have shown that successes have been recorded in converting some antibiotic contaminated wastewater to biogas in advance anaerobic digesters. Moreover, not all medical wastes are degradable, the use of placentas, hospital cotton waste, human urine, waste blood and surgery waste has been used in biogas plants built at close proximity to hospitals, in some cases. However, such plants are few and are only located in Tanzania, India and Philippines, among others to generate biogas to power hospitals, boil hot water needed by patients and for cooking. This is because the level of awareness as regards the dangers associated with indiscriminate disposal of medical and pharmaceutical waste is low and hence the development of waste disposal policy by countries is often overlooked. The implication of this is the spread of diseases in affected areas which can results in epidemics. It is therefore necessary to formulate policies that allow the harnessing of these wastes to biogas/ bioenergy or the creation of better waste management practices that is environmentally safe.

Objective: This study aims to identify the obstacles to recycling and environmental sustainability habits in a university hospital's operating room (OR) environment in Turkey and lay the groundwork for potential solutions. Methods: A questionnaire was used to measure current views among the 140 OR staff members aged 20-54 years. The survey assessed awareness and behaviors of recycling at home and in the OR, as well as awareness of environmentally safe anaesthesia practices. Results: Half of the participants believed that ORs significantly affected their carbon footprint, and most agreed that these environmental effects could be reduced. The primary barriers to recycling were inadequate knowledge, negative staff attitudes and insufficient services. Notably, 76% of participants paid attention to segregating OR waste, yet many lacked formal education about the environmental impact of their practices. Approximately 89% agreed that the environmental effects of ORs could be further reduced, with education being a critical need. Conclusion: The healthcare sector's contribution to carbon emissions and waste production is significant, especially in ORs. The lack of education regarding ecological implications is concerning. Implementing standardized training programs and enhancing recycling services can substantially reduce the environmental impact of ORs, highlighting the need for a more sustainable healthcare system.

The prevalent use of unsustainable polymers in current X‐ray scintillators poses a significant environmental concern. The advancement of biodegradable X‐ray scintillators holds promise in mitigating escalating environmental issues tied to electronic or medical waste and carbon footprints. Herein, a biodegradable and flexible X‐ray scintillation film is presented employing lead‐free 0D Cs3Cu2I5 perovskite nanoparticles integrated into densified‐delignified wood (Cs3Cu2I5@D‐Wood). The Cs3Cu2I5@D‐Wood film demonstrates precise and detailed X‐ray imaging capabilities, achieving a high spatial resolution of 10 line pairs per millimeter (lp·mm−1). To minimize the environmental impact associated with disposal, metal and halide ions (e.g., Cs+, Cu+, I−) from Cs3Cu2I5@D‐Wood can be easily retrieved by a simple solvent extraction process. The approach showcases the potential of biodegradable wood‐based X‐ray scintillation screens as alternatives to conventional, plastic‐based screens. This offers a significant contribution to environmental sustainability by reducing electronic or medical waste. [ABSTRACT FROM AUTHOR]

Serological detection of syphilis‐specific antibodies is the most widely used clinical method for diagnosing syphilis. However, the current methods in clinical practice are too diverse, complicating result interpretation and wasting medical resources. To meet the resultant demand for a simple fast naked‐eye detection method, we employed the bacterial cell‐binding domain (CBD) of bacteriophage lysin to functionalize bio‐microparticles (engineered non‐culturable red‐colored Staphylococcus aureus bacteria), forming a bioprobe that can detect the syphilis‐specific antibodies from human serum in 5 min with naked eyes. Specifically, CBD is bioengineered by fusion with one of three antigens of the syphilis‐causing bacteria Treponema pallidum separately. The three resulting fusion proteins bind to the bacteria surface through the CBD motif, generating a bioprobe with the antigens exposed. When the bioprobe is added to the serum samples collected from the syphilis patients, the syphilis‐specific antibodies bind the antigens on the bioprobes and cross‐link them, forming eye‐visible red aggregates for the naked‐eye antibody detection. The bioprobe was validated on 209 clinical samples, revealing its high clinical sensitivity and specificity. Exploiting the natural biorecognition between the bacteria‐specific phage‐derived species and the phage host bacteria represents a promising strategy for producing facile probes for rapid point‐of‐care testing of infectious diseases.

MEDICAL wastes , *ACQUISITION of data , *EPIDEMICS - Abstract
During major epidemic outbreaks, the generation of medical waste has increased dramatically. Medical waste becomes more infectious than usual under these circumstances, and turnover personnel may be affected or become ill due to infection. These unforeseen factors have significantly increased the complexity of task assignment for medical waste turnover personnel. In addition, medical waste requires daily collection and disposal. To ensure the smooth collection of medical waste, the reasonable arrangement of turnover personnel is particularly important. It is well known that the fewer times medical waste turnover personnel are assigned to different temporary storage points for medical waste, the less likely cross-infection occurs. In this paper, aiming to minimize the number of assignments and the number of medical waste turnover personnel assigned, while ensuring a balanced collection task for the assigned medical waste turnover personnel, a multi-objective medical waste turnover personnel assignment model is established, aiming to minimize the number of assignments while ensuring a balanced workload among the assigned personnel. To facilitate solving, this paper converts nonlinear constraints in the model into linear constraints using the Big M method. Finally, based on the medical waste collection and disposal data of a medical waste disposal unit in a certain district of Chengdu city on April 13, 2022, relevant numerical examples are designed and solved using IBM ILOG Cplex Studio IDE 12.7.1, thereby verifying the efficiency and applicability of the model. Our model is designed to provide a relatively rational personnel scheduling plan under the context of major epidemic outbreaks, where the uncertainty for medical waste collection and transportation personnel is heightened. This model aims to minimize the number of personnel required for medical waste collection and transportation while ensuring a balanced workload distribution among them. In comparison to manual scheduling methods, our model significantly enhances the efficiency of scheduling. [ABSTRACT FROM AUTHOR]

Over the last 15 years, there has been substantial growth in the installation of medical cyclotrons. This is mainly due to the increased demand for the production of positron emission tomography radiopharmaceuticals. In every country, there is a regulatory body that regulates the uses of medical cyclotron intending to protect occupational workers, the public, and the environment. It regulates the entire stages of such facilities, which mainly controls regulatory activities such as construction, commissioning, operation, and decommissioning. This article primarily highlights the key practices for planning and installation of a medical cyclotron facility (MCF). It also covers the particular aspects that should be considered in the early stages of project planning and provides information for best practices and challenges. If these aspects are properly addressed, then it ensures the safe operation of the MCF. The texts also elaborate on the necessary requirements for effective planning of the MCF, such as layout and space considerations, workload plan and maximum research capacity of the institute and equipment, shielding requirements, water cooling circuit, storage of radioactive components, management of radioactive waste from medical cyclotron and radiochemistry laboratory, construction and commissioning project management, exhaust system and filtration options, plans for staffing and training, and combination of equipment safety systems and building safety systems.

The annual production of medical waste from healthcare facilities in Pakistan is around 250,000 tons. An effective waste management system is essential for disposing of hazardous medical waste, and incineration is considered the most effective and accessible technology. Disposal of medical waste ash in landfills without proper treatment could lead to groundwater contamination due to leachate. This research paper aims to evaluate the feasibility of using hospital waste ash obtained from the National Cleaner Production Center (NCPC) in Rawalpindi as a partial replacement for cement. The primary variable in this study was the amount of hospital waste ash (0%, 3%, 7%, and 10% by weight of cement), while the amount of cementitious material, water-to-cement ratio, and fine and coarse aggregate content were kept constant. A total of 36 cubes were cast, with nine cubes for each replacement level for curing periods of 7, 14, and 28 days. The slump value and density of fresh concrete decreased with the increase in the proportion of hospital waste ash in the mix. The compressive strength of mixes with 3% hospital waste ash was higher than that of the control mix. The best results (20.13 MPa) were obtained from the 3% mix after 28 days of curing, while the result obtained with the 7% mix was nearly equal to that of the control mix. [ABSTRACT FROM AUTHOR]
