A Comparative Study of Effects of Biodegradable and Non-biodegradable Microplastics on the Growth and Development of Black Soldier Fly Larvae (Hermetia illucens).

Purpose: This study aimed to investigate the digestion process of biodegradable and non-biodegradable microplastics (MPs) within black soldier fly larvae (BSFL) and assess their impact on larval growth and development. The goal was to understand the fate of MPs within BSFL, considering their potential for waste conversion polluted with MPs. Methods: BSFL were exposed to two types of MPs, and their growth, development, potential accumulation and excretion of MPs were monitored. Results: The findings revealed that the MPs accumulated solely in the larval gut and had no adverse effects on the growth and development of BSFL. Larvae efficiently excreted MPs before reaching the pupation stage. Conclusion: This research emphasizes the potential of BSFL as a bioconversion agent for organic waste, even in the presence of MPs. The effective excretion of MPs by BSFL before pupation suggests their ability to mitigate potential harm caused by MP accumulation. The fact that BSFL may excrete MPs before pupation would contribute to their safe use as animal feedstock. A careful evaluation of the effects of using BSFL reared on contaminated substrates especially containing visually non-detectable residuals like nanoplastics, chemicals or toxic metals and further examination of the broader implications for waste management and sustainable livestock farming remains important. Graphical Abstract: Experimental design outlining the workflow for the analyses used to investigate the effect of two types of microplastics, polyamide (PA), and polylactic acid (PLA), on growth and development of black soldier fly larvae.

Knowns and unknowns of plastic waste flows in the Netherlands.

Plastic entering the environment is a growing threat for ecosystems. We estimate the annual mass of known Dutch plastic waste generated and littered and where it ends up. We use two methods: (1) a material flow analysis of plastic waste separately collected from 13 economic sectors (including households, industry and imports) and estimate the amount sent to processing plants or exported and (2) a mismanagement model from observations of litter (on Dutch beaches and riverbanks) plus estimates of inadequately managed exported plastic scraps entering the environment abroad. In 2017 (the most recent complete data set available), an estimate of 1990 (±111) kilotonnes [kt] of plastic waste was separately collected. The top three plastic waste generating sectors (74% of the total) were households, clothing and textiles, and importation. Our mismanagement model estimates that 4.3-21.2 kt enters the environment annually; almost all of which occurs in foreign countries after inadequate management of imported Dutch waste. We highlight unknowns, including the source and/or destination of imported (623 kt) and exported (514 kt) plastics, plastics in non-household mixed waste streams and the plastic fraction of some separately collected waste, for example, e-waste. Our results stress the need for improved monitoring and reporting of plastic waste. Beyond the Netherlands, our recommendations could also help other high-income countries' decision-makers reach their circular economy goals.

How Not To Fix a Tibial Fracture: A Case Report on Treatment By a Quack.

Quackery in the orthopaedic profession has existed for quite a long time. Due to the shortage of orthopaedic healthcare staff in public hospitals and the high costs in private facilities, members of disadvantaged communities turn to unlicensed and unskilled practitioners (quacks). The main factors responsible for the increased number of quacks performing orthopaedic treatment are illiteracy, high treatment cost, mismatch in the orthopaedic surgeon-to-population ratio, especially in rural areas, and the absence of any form of health insurance. Moreover, their easy availability and offer of low-cost treatment draw innocent and illiterate patients to them, even though these quacks perform orthopaedic treatment in the most unhygienic, unsterilized, and unconventional manner. The government should intervene and take measures to make orthopaedic treatment more affordable and accessible, especially to the rural population.

Investigation of litigation in trauma orthopaedic surgery.

BACKGROUND: It has been said that the number of orthopaedic claims has increased in the last few years. Investigation through the most prevalent cause would help to prevent further cases. AIM: To review the cases of medical complaints in orthopedic patients who had been involved in a traumatic accident. METHODS: A retrospective multi-center review of trauma orthopaedic-related malpractice lawsuits from 2010 to 2021 was conducted utilizing the regional medicolegal database. Defendant and plaintiff characteristics along with fracture location, allegations, and litigation outcomes were investigated. RESULTS: A total of 228 claims referred to trauma-related conditions with a mean age of 31.29 ± 12.56 were enrolled. The most common injuries were at hand, thigh, elbow, and forearm, respectively. Likewise, the most common alleged complication was related to malunion or nonunion. In 47% of the cases, the main problem that led to the complaint was the inappropriate or insufficient explanation to the patient, and in 53%, there was a problem in the surgery. Eventually, 76% of the complaints resulted in a defense verdict, and 24% resulted in a plaintiff verdict. CONCLUSION: Surgical treatment of hand injuries and surgery in non-educational hospitals received the most complaints. The majority of litigation outcomes were caused by a physician's failure to fully explain and educate the traumatic orthopedic patients and technological errors.

Hybrid Closed Loop Overcomes the Impact of Missed or Suboptimal Meal Boluses on Glucose Control in Children with Type 1 Diabetes Compared to Sensor-Augmented Pump Therapy.

Background: It is unclear whether hybrid closed-loop (HCL) therapy attenuates the metabolic impact of missed or suboptimal meal insulin bolus compared with sensor-augmented pump (SAP) therapy in children with type 1 diabetes in free-living conditions. Methods: This is an ancillary study from a multicenter randomized controlled trial that compared 24/7 HCL with evening and night (E/N) HCL for 36 weeks in children between 6 and 12 years old. In the present study, the 60 children from the E/N arm underwent a SAP phase, an E/N HCL for 18 weeks, then a 24/7 phase for 18 weeks, extended for 36 more weeks. The last 28-30 days of each of the four phases were analyzed according to meal bolus management (cumulated 6817 days). The primary endpoint was the percentage of time that the sensor glucose was in the target range (TIR, 70-180 mg/dL) according to the number of missed boluses per day. Findings: TIR was 54% ± 10% with SAP, 63% ± 7% with E/N HCL, and steadily 67% ± 7% with 24/7 HCL. From the SAP phase to 72 weeks of HCL, the percentage of days with at least one missed meal bolus increased from 12% to 22%. Estimated marginal (EM) mean TIR when no bolus was missed was 54% (95% confidence intervals [CI] 53-56) in SAP and it was 13% higher (95% CI 11-15) in the 24/7 HCL phase. EM mean TIR with 1 and ≥2 missed boluses/day was 49.5% (95% CI 46-52) and 45% (95% CI 39-51) in SAP, and it was 15% (95% CI 14-16) and 17% higher (95% CI 6-28), respectively, in the 24/7 HCL phase (P < 0.05 for all comparisons vs. SAP). Interpretation: HCL persistently improves glycemic control compared with SAP, even in case of meal bolus omission. ClinicalTrials.gov (NCT03739099).

Missed diagnosis or misdiagnosis: Common pitfalls in genetic testing.

Genetic testing has the power to identify individuals with increased predisposition to disease, allowing individuals the opportunity to make informed management, treatment and reproductive decisions. As genomic medicine continues to be integrated into aspects of everyday patient care and the indications for genetic testing continue to expand, genetic services are increasingly being offered by non-genetic clinicians. The current complexities of genetic testing highlight the need to support and ensure non-genetic professionals are adequately equipped with the knowledge and skills to provide services. We describe a series of misdiagnosed/mismanaged cases, highlighting the common pitfalls in genetic testing to identify the knowledge gaps and where education and support is needed. We highlight that education focusing on differential diagnoses, test selection and result interpretation is needed. Collaboration and communication between genetic and non-genetic clinicians and integration of genetic counsellors into different medical settings are important. This will minimise the risks and maximise the benefits of genetic testing, ensuring adverse outcomes are mitigated.

Medical Mismanagement in Southern US Immigration and Customs Enforcement Detention Facilities: A Thematic Analysis of Secondary Medical Records.

Detention facilities in the southern US hold a large percentage of individuals detained in the US and have amassed numerous reports of medical mismanagement. The purpose of this study was to evaluate expert declarations of individuals residing in these facilities to assess the appropriateness of medical care provided. We analyzed 38 medical expert declarations from individuals in detention from 2020 to 2021. A thematic analysis was conducted to explore the management of medical conditions. Major themes include inadequate workup, management and treatment of medical conditions, psychiatric conditions, and medical symptoms. Subthemes identified include incorrect workup, failure to refer to a specialist, incorrect medications and/or treatments, missed or incorrect diagnoses, and exacerbation of chronic conditions. This study supports growing evidence of medical mismanagement and neglect of individuals while in immigration detention. Enhanced oversight and accountability around medical care in these facilities is critical to ensure the quality of medical care delivered meets the standard of care.

A huge retroperitoneal ganglioneuroma in a middle-aged patient: Report of a diagnostically challenging case with review of the literature.

Ganglioneuromas (GNs) are benign, slow-growing tumors of neural crest cell origin. On rare occasions, adipose cells have been detected in these tumors. The present study reported a case of a huge retroperitoneal GN misdiagnosed and mismanaged as a liposarcoma. A 54-year-old male patient presented with gradually progressing dull back pain with abdominal discomfort for the past 6 months. The patient had abdominal distention and mild right abdominal tenderness. Ultrasound of the abdomen and pelvis revealed a large right-sided retroperitoneal mass. Contrast-enhanced computed tomography findings were consistent with sarcoma. Cytologic examination was suggestive of liposarcoma. A decision was made to start neoadjuvant radiochemotherapy, which proved ineffective. Complete surgical excision of the mass was performed via a midline laparotomy. Histopathology of the mass confirmed the diagnosis of GN. At two years post-operation, the patient developed a recurrence in the subhepatic area with the same diagnosis and the recurrent mass was surgically removed. Initially, the imaging findings were not sufficiently specific to establish the diagnosis. Rarely, cytologic techniques have detected adipose cells in these tumors, resulting in misdiagnosis. Hence, histopathology is the gold standard for definitive diagnosis. Preoperative diagnosis of GN is difficult due to the lack of specific clinical manifestations, radiological confusion with other tumors and the presence of adipocytes in rare cases, leading to misdiagnosis and mismanagement.

Life Cycle Assessment of Microplastics Reveals Their Greater Environmental Hazards than Mismanaged Polymer Waste Losses.

Concern about microplastic pollution sourced from mismanaged plastic waste losses to drainage basins is growing but lacks relevant environmental impact analyses. Here, we reveal and compare the environmental hazards of aquatic macro- and microplastic debris through a holistic life cycle assessment approach. Compared to polymeric debris, microplastics, especially smaller than 10 µm, exhibit higher freshwater ecotoxicity enhanced by watersheds' high average depth and low water temperature. High microplastic concentration within drainage basins can also cause air pollution regarding particulate matter formation and photochemical ozone formation. The environmental drawbacks of plastic mismanagement are then demonstrated by showing that the microplastic formulation and removal in drinking water treatment plants can pose more than 7.44% of the total ecotoxicity effect from plastic wastes' (microplastics') whole life cycle. Specifically, these two life cycle stages can also cause more than 50% of the plastic wastes' life cycle ecotoxicity effect related to organic chemical emissions. Therefore, reducing environmentally harmful plastic losses through advanced plastic waste recycling, collection, and effective microplastic removal technologies needs future investigation.

Human-derived effects and failure in management drive coastal urban foredune degradation and novel vegetation structure.

Urbanization can drive significant decay in species diversity and abundance; in dune ecosystems the composition changes at a pace with changes in spatial fragmentation. Infrastructure deployment and human activities may provoke synergistically a reduction in dune patch size and/or habitat loss and thus a potential for rapid establishment of exotic species, producing a 'novel' habitat configuration. In this study we examine the effects of coastal urbanization and associated human activities in foredune patch fragmentation and changes in floristic composition and abundance in an urban-rural gradient. Using samples from a recently bulldozed and managed urban foredune area, we assess the legacy of erroneous practices associated with planting of exotic species in urban settings. We found a significant increase in foredune fragmentation, estimated as the occurrence of marks left by vehicles (4WD, 2WD) and people in foredunes close to or within urban settings. A marked change from native to non-native plant species was found from rural to urban environments, with non-native species contributing to increase species richness in urban settings. A positive relationship of non-native species with level of foredunes fragmentation was found. Dominance of non-native species was persistent through time in altered foredune patches. Our findings showed that incorporation of non-native species for aesthetic or engineering purposes in bulldozed foredunes, could limit colonization of native species through rapid establishment and complete dominance of non-native ones. Historical activities associated with coastal infrastructure upgrades seem to configure the present foredune floristic pattern present in urbanized coasts. Management strategies correcting past erroneous actions and promoting foredune rehabilitation could help the conservation of services that these 'novel' habitats provide in coastal urban environments.

Activity and emission inventory of open waste burning at the household level in developing countries: a case study of Semarang City.

In this study, total burned household waste and the potential emissions released from waste burning in Semarang City, Indonesia, were estimated. Waste piles were monitored using the transect walk survey method in 16 sub-districts of Semarang City. Carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC), nitrous oxide (NOx), and total particulate matter (TPM) were directly analyzed through a simulation of waste combustion. The potential emissions from other pollutants were predicted by multiplying the weight of the burned waste by the emission factors available in the literature. The estimated waste burned in Semarang City in 2020-2021 was 58.8 Gg/year, or approximately 9.70% of the total waste generated in Semarang City. This estimation exceeds local government estimates of 2020 by two-fold. Peri-urban areas (both inner and outer) were identified as the most significant contributors to waste burning. Further, garden waste was the most burned waste (73.61%), followed by plastic waste (17.45%). Other wastes, including paper, leather, textile, rubber, and food, were also burned. Overall, a decrease in the activity of waste burning is an important step for reducing the potential of air pollution and climate change.

Litigations in trauma and orthopaedic surgery: analysis and outcomes of medicolegal claims during the last 10 years in the United Kingdom National Health Service.

This study analyses the outcomes of litigation claims in trauma and orthopaedic surgery between 2008/2009 and 2018/2019.Utilizing a formal request to the NHS Resolution under the Freedom of Information Act, the data related to claims against orthopaedic surgery were obtained. A total of 8548 claims were analysed and re-grouped to perform a meaningful analysis for the type of claims and the type of injuries.The total pay-out cost for the settled claims was over £1.2 billion. The most common types of claims were related to mismanagement (39.0%), diagnostic issues (17.6%), perioperative issues (15.9%) and alleged incompetence (10.2%). The most common primary causes for claims were patients' dissatisfaction (52.2%), damage to the limbs (19.0%) and neurological injuries (9.2%).The highest amounts of damages paid out were related to patients' dissatisfaction (37.7%), burns and bruising (31.0%), neurological injuries (24.5%) and damage to the limbs (22.3%). The number of claims and the pay-out cost were found to be steadily increasing; however, there was a slightly declining trend observed during the last two years.The cost of litigation continues to have a significant financial impact on the NHS. The recent declining trend is encouraging; however, surgeons need to take consistent diligent steps to avoid preventable causes that lead to litigation claims.The proposed change in the coding system of claims in the NHS Resolution will not only help to formulate a clear classification system but will also improve the learning from previous experience.

Antioxidants other than vitamin C may be detected by glucose meters: Immediate relevance for patients with disorders targeted by antioxidant therapies.

Owing to their ease of use, glucose meters are frequently used in research and medicine. However, little is known of whether other non-glucose molecules, besides vitamin C, interfere with glucometry. Therefore, we sought to determine whether other antioxidants might behave like vitamin C in causing falsely elevated blood glucose levels, potentially exposing patients to glycemic mismanagement by being administered harmful doses of glucose-lowering drugs. To determine whether various antioxidants can be detected by seven commercial glucose meters, human blood samples were spiked with various antioxidants ex vivo and their effect on the glucose results were assessed by Parkes error grid analysis. Several of the glucose meters demonstrated a positive bias in the glucose measurement of blood samples spiked with vitamin C, N-acetylcysteine, and glutathione. With the most interference-sensitive glucose meter, non-blood solutions of 1 mmol/L N-acetylcysteine, glutathione, cysteine, vitamin C, dihydrolipoate, and dithiothreitol mimicked the results seen on that glucose meter for 0.7, 1.0, 1.2, 2.6, 3.7 and 5.5 mmol/L glucose solutions, respectively. Glucose meter users should be alerted that some of these devices might produce spurious glucose results not only in patients on vitamin C therapy but also in those being administered other antioxidants. As discussed herein, the clinical relevance of the data is immediate in view of the current use of antioxidant therapies for disorders such as the metabolic syndrome, diabetes, cardiovascular diseases, and coronavirus disease 2019.

Transparência, corrupção e má gestão: uma análise dos municípios brasileiros / Transparencia, corrupción y mala gestión: un análisis de los municipios brasileños / Transparency, corruption, and mismanagement: an analysis of Brazilian municipalities

Artigo Compromisso institucional com a transparência pública tem relação negativa com corrupção e má gestão governamental? A instituição de Lei de Acesso à Informação (LAI) reduz o custo de acesso à informação pública e o controle dos governantes sobre ela, possibilitando o monitoramento do governo. Assim, maior transparência melhoraria a performance governamental. Para testar a hipótese, usamos modelos de regressão linear para 320 municípios brasileiros. Empregamos 3 medidas do compromisso institucional dos municípios com a transparência pública: a) a regulamentação da LAI no município; b) o grau de regulamentação com base nos dispositivos da LAI em nível local; e c) o tempo de adesão como medida de institucionalização da transparência pública. Como medida de performance, consideramos irregularidades de corrupção e má gestão identificadas nos relatórios de auditorias da Controladoria-Geral da União via sorteios públicos (2011-2015), com classificação usando aprendizado de máquina não supervisionado. Os resultados da análise são 3: a) a adesão dos municípios à LAI ainda é muito reduzida; b) nos municípios que aderiram, transparência não apresenta associação com a performance governamental; e c) apenas desenvolvimento econômico e qualidade da burocracia apresentam correlação negativa com o número de irregularidades. Os resultados indicam que o esforço na direção de uma gestão mais transparente ainda não gerou os resultados esperados.

Resumen ¿El compromiso institucional con la transparencia pública reduce la corrupción y la mala gestión del gobierno? La institución de la Ley de Acceso a la Información (LAI) reduce el costo de acceso a la información pública y el control de los funcionarios del gobierno sobre ella, lo que permite que el gobierno sea monitoreado. Por lo tanto, una mayor transparencia mejoraría el desempeño del gobierno. Para probar la hipótesis, usamos modelos de regresión lineal en 320 municipios brasileños. Empleamos tres medidas del compromiso institucional de los municipios con la transparencia pública: la regulación de la LAI en el municipio; el grado de regulación basado en las disposiciones de la LAI a nivel local; y el tiempo de adhesión como medida de institucionalización de la transparencia pública. Como medida de rendimiento, consideramos las irregularidades de corrupción y mala gestión identificadas en los informes de auditoría de la Contraloría General de la Federación a través de sorteos públicos (2011-2015), con clasificación mediante aprendizaje automático no supervisado. Los resultados del análisis son tres: la adhesión de los municipios a la LAI todavía es muy baja; en los municipios que se adhirieron la transparencia no está asociada al desempeño del gobierno; y solo el desarrollo económico y la calidad de la burocracia tienen correlación negativa con el número de irregularidades. Los resultados indican que el esfuerzo hacia una gestión más transparente aún no ha generado los resultados esperados.

Abstract Does institutional commitment to public transparency reduce corruption and public mismanagement? The regulation of freedom of information laws (FOI) reduces the cost of accessing public information and the control of government officials over it, allowing for monitoring of the government. Thus, greater transparency improves government performance. To test the hypothesis, we used linear regression models for 320 Brazilian municipalities. We employ three measures of municipality institutional commitment to public transparency: FOI regulation in the municipality; the degree to which the local level regulation was based on the national law's provisions; and time the municipality took to adhere to the legislation, as a measure of institutionalization of public transparency. As a performance measure, we consider corruption and mismanagement irregularities identified in the audit reports of the Comptroller General of Brazil (2011-2015), with classification using unsupervised machine learning. The results are threefold: the municipalities' adherence to FOI is still very low; in the municipalities that regulated the law locally, transparency is not seen to be associated with government performance; only economic development and quality of bureaucracy have a negative correlation with the number of irregularities. These results indicate that the effort towards more transparent management has not yet generated the expected results.

Estimation of plastic waste inputs from land into the Persian Gulf and the Gulf of Oman: An environmental disaster, scientific and social concerns.

It has been reported that, the huge amount of plastic waste is present in marine environments. This study evaluated solid waste generation, management, disposal approaches, and the amount of plastic waste entered into the Persian Gulf and the Gulf of Oman in 2016. The findings showed that waste in the Persian Gulf and the Gulf of Oman regions has been mismanaged by 65% and 81%, respectively. According to our estimates, about 1634.9 k-tons (Kt) and 204.6 Kt of plastic waste have been, respectively, generated by the Persian Gulf and the Gulf of Oman littoral states in 2016. Most likely, the mass of plastic waste entering the Persian Gulf and the Gulf of Oman in 2016 was ranged from 155 to 413.4 Kt and 29.2-77.9 Kt, respectively. Without implementation of effective waste management strategies, it is estimated that by 2030, the mass of plastic waste entering the Persian Gulf will increase to 199.4-531.6 Kt, while in the Gulf of Oman it would be about 40.4-107.7 Kt. The entry of plastic waste into the Persian Gulf and the Gulf of Oman has been expected to increase by 29% and 38% in 2030, respectively. As a result, the related cumulative environmental and health effects can be more intensive. It can be emphasized that all countries located in the coastal areas of the Persian Gulf and the Gulf of Oman need to modify their solid waste management, plastic waste in particular, policies to conserve sensitive marine ecosystems.

Para el análisis de los datos se realizaron procedimientos descriptivos y la regresión binomial negativo. En general, los resultados indicaron que la posibilidad de reelección del alcalde y el desempeño de los consejos municipales afectaron significativamente la incidencia de la corrupción. A su vez, la mala gestión mostró una relación significativa con el perfil del votante y el desempeño de los consejos municipales. Estos hallazgos destacan la relevancia de los consejos municipales como instrumento de seguimiento y fiscalización de la aplicación de los recursos públicos destinados a la enseñanza básica de los municipios brasileños.

Abstract This research analyzes the socioeconomic and political factors that influence the occurrence of corruption and mismanagement in public spending on basic education in Brazilian municipalities. The sources of data were the inspection reports of the Comptroller General of the Union during 2011 to 2015; and the websites of the Federation of Industries of the State of Rio de Janeiro, the Brazilian Institute of Geography and Statistics, the Superior Electoral Court, and the National Treasury Secretariat. The data analysis adopted descriptive procedures and binomial negative regression. Overall, the results indicate that the possibility of reelection of the mayor and the performance of municipal councils affected the incidence of corruption. In turn, an occurrence of mismanagement shows a significant relationship with the voter's profile and the performance of municipal councils. These findings highlighted the relevance of municipal councils as an instrument for monitoring and supervising public spending on basic education of Brazilian municipalities.

Estimation of plastic waste inputs from land into the Caspian Sea: A significant unseen marine pollution.

It has been proven that there is an extensive bulk of plastic debris in marine ecosystems. The present study analyzed solid waste generation, its management and final disposal methods in Caspian Sea coastal countries, and the amount of plastic waste entering the Caspian Sea. The results showed that, on average, more than 90% of waste in the Caspian Sea coastal countries is mismanaged. According to our estimates, 425 kilotons (Kt) of plastic waste was generated by Caspian Sea coastal countries in 2016, of which, with high probability, 58-155 Kt find their way to the Caspian Sea. It is estimated that without improved waste management infrastructures, the amount of plastic waste entering the Caspian Sea will increase to 68-182 Kt by 2030, an increase of about 15%. Accordingly, the related cumulative environmental and health problems could be more severe. All countries located in the coastal areas of the Caspian Sea should revise their solid waste and plastic waste management programs to protect that sensitive marine ecosystem.
