RESUMEN
Background: This study examined inpatient mortality factors in geriatric patients with acute myeloid leukemia (AML) using data from the 2016 to 2020 National Inpatient Sample. Methods: Identifying patients through ICD-10 codes, a total of 127,985 individuals with AML were classified into age categories as follows: 50.58% were 65 to 74 years, 37.74% were 75 to 84 years, and 11.68% were 85 years or older. Statistical analysis, conducted with STATA, involved Fisher's exact and Student's t tests for variable comparisons. Mortality predictors were identified through multivariate logistic regression. Results: Various hospital and patient-level factors, including an increase in age, race, a higher Charlson Comorbidity Index score, insurance status, and specific comorbidities such as atrial fibrillation and protein-calorie malnutrition, independently elevated the risk of inpatient mortality. Asthma, hyperlipidemia, and inpatient chemotherapy were linked to lower mortality. Although there was no statistically significant mortality rate change from 2016 to 2020, a decline in chemotherapy use in the eldest age group was noted. Conclusion: This study highlights the complexity of factors influencing inpatient mortality among geriatric patients with AML, emphasizing the need for personalized clinical approaches in this vulnerable population.
RESUMEN
Microplastics (MPs) have accumulated in the oceans, causing adverse effects on marine organisms and the environment. Biodegradable polylactic acid (PLA) is considered as an excellent substitute for traditional petroleum-based plastics, but it is difficult to degrade completely and easily become MPs in the marine environment. To test the ecological risk of bio-based PLA, we exposed thick-shelled mussels (Mytilus coruscus) to bio-based PLA and petroleum-based polystyrene (PS) (at 102, 104, and 106 particles/L) for 14 days. The significant increase in enzyme activities related to oxidative stress and immune response showed that mussels were under physiological stress after MP ingestion. While enzyme activities of nerve conduction and energy metabolism were significantly disturbed after exposure. Meanwhile, normal physiological activities in respiration, ingestion and assimilation were also suppressed in association with enzyme changes. The negative effects of PS and PLA in mussels were not differentiated, and further integration analysis of integrated biomarker response (IBR) and principal component analysis (PCA) also showed that PLA would induce adverse effects in mussels and ecological risks as PS, especially at environmental concentrations. Therefore, it is necessary to pay more attention to the environmental and ecological risk of bio-based MP PLA accumulating in the marine environment.

Background: This study investigated the impact of COVID-19 on patients with sickle cell crisis (SCC) using National Inpatient Sample (NIS) data for the year 2020. Methods: A retrospective cohort analysis was conducted utilizing International Classification of Diseases (ICD-10) codes to identify adults who were admitted with a principal diagnosis of sickle cell crisis. The primary outcomes examined were inpatient mortality, while the secondary outcomes assessed included morbidity, hospital length of stay, and resource utilization. Analyses were conducted with STATA. Multivariate logistic and linear regression analyses were used to adjust for confounding variables. Results: Of 66,415 adult patients with a primary SCC diagnosis, 875 were identified with a secondary diagnosis of COVID-19 infection. Unadjusted mortality rate was higher for SCC patients with COVID-19 (2.28%) compared to those without (0.33%), with an adjusted odds ratio (aOR) of 8.49 (p = 0.001). They also showed increased odds of developing acute respiratory failure (aOR = 2.37, p = 0.003) and acute kidney injury requiring dialysis (aOR = 8.66, p = 0.034). Additionally, these patients had longer hospital stays by an adjusted mean of 3.30 days (p < 0.001) and incurred higher hospitalization charges by an adjusted mean of USD 35,578 (p = 0.005). Conclusions: The SCC patients with COVID-19 presented higher mortality rates, increased morbidity indicators, longer hospital stays, and substantial economic burdens.
RESUMEN
Enterobacter cloacae belongs to Enterobacter genus. It is a common gram-negative, facultative anaerobic, rod-shaped organism. It causes a variety of nosocomial infections including urinary tract infection, pneumonia, wound infection, osteomyelitis and endocarditis. Over time Enterobacter cloacae complex (ECC) has developed to be resistant to antibiotics including carbapenem. It has been rarely reported to cause gas gangrene and never been reported to cause pseudoaneurysm (PA) of transplant renal artery. We report and share our experience with this rare case of gas forming and muti-drug resistant ECC which led to mycotic PA of transplant renal artery, complicated by bleeding and infected hematoma and which resulted in graft nephrectomy.
RESUMEN
This work implements the recently developed nth state Markovian jumping particle swarm optimisation (PSO) algorithm with local search (NS-MJPSOloc) awareness method to address the economic/environmental dispatch (EED) problem. The proposed approach, known as the Non-dominated Sorting Multi-objective PSO with Local Best (NS-MJPSOloc), aims to enhance the performance of the PSO algorithm in multi-objective optimisation problems. This is achieved by redefining the concept of best local candidates within the search space of multi-objective optimisation. The NS-MJPSOloc algorithm uses an evolutionary factor-based mechanism to identify the optimum compromise solution, a Markov chain state jumping technique to control the Pareto-optimal set size, and a neighbourhood's topology (such as a ring or a star) to determine its size. Economic dispatch refers to the systematic allocation of available power resources in order to fulfill all relevant limitations and effectively meet the demand for electricity at the lowest possible operating cost. As a result of heightened public consciousness regarding environmental pollution and the implementation of clean air amendments, nations worldwide have compelled utilities to adapt their operational practises in order to comply with environmental regulations. The (NS-MJPSOloc) approach has been utilised for resolving the EED problem, including cost and emission objectives that are not commensurable. The findings illustrate the efficacy of the suggested (NS-MJPSOloc) approach in producing a collection of Pareto-optimal solutions that are evenly dispersed within a single iteration. The comparison of several approaches reveals the higher performance of the suggested (NS-MJPSOloc) in terms of the diversity of the Pareto-optimal solutions achieved. In addition, a measure of solution quality based on Pareto optimality has been incorporated. The findings validate the effectiveness of the proposed (NS-MJPSOloc) approach in addressing the multi-objective EED issue and generating a trade-off solution that is both optimal and of high quality. We observed that our approach can reduce â¼ 6.4% of fuel costs and â¼ 9.1% of computational time in comparison to the classical PSO technique. Furthermore, our method can reduce â¼ 9.4% of the emissions measured in tons per hour as compared to the PSO approach.
RESUMEN
The impact of environmental factors on the health of the endangered Chinese sturgeon (Acipenser sinensis) and the potential hazards associated with sample collection for health monitoring pose urgent need to its conservation. In this study, Chinese sturgeons were selected from indoor and outdoor environments to evaluate metabolic and tissue damage indicators, along with a non-specific immune enzyme in fish mucus. Additionally, the microbiota of both water bodies and fish mucus were determined using 16S rRNA high-throughput sequencing. The correlation between the indicators and the microbiota was investigated, along with the measurement of multiple environmental factors. The results revealed significantly higher levels of two metabolic indicators, total protein (TP) and cortisol (COR) in indoor fish mucus compared to outdoor fish mucus (p < 0.05). The activities of acid phosphatase (ACP), alkaline phosphatase (ALP), creatine kinase (CK), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) were significantly higher in indoor fish, serving as indicators of tissue damage (p < 0.05). The activity of lysozyme (LZM) was significantly lower in indoor fish (p < 0.01). Biomarker analysis at the phylum and genus levels in outdoor samples revealed that microorganisms were primarily related to the catabolism of organic nutrients. In indoor environments, microorganisms displayed a broader spectrum of functions, including ecological niche establishment, host colonization, potential pathogenicity, and antagonism of pathogens. KEGG functional enrichment corroborated these findings. Dissolved oxygen (DO), electrical conductivity (EC), ammonia nitrogen (NH3-N), turbidity (TU), and chemical oxygen demand (COD) exerted effects on outdoor microbiota. Temperature (TEMP), nitrate (NO3-), total phosphorus (TP), and total nitrogen (TN) influenced indoor microbiota. Changes in mucus indicators, microbial structure, and function in both environments were highly correlated with these factors. Our study provides novel insights into the health impacts of different environments on Chinese sturgeon using a non-invasive method.

OBJECTIVE: To assess the predictive ability of the laboratory risk indicator for necrotising fasciitis (LRINEC) score for lower extremity amputation in patients with moderate to severe diabetic foot infection (DFI). STUDY DESIGN: Observational study. Place and Duration of the Study: Department of General Surgery, Combined Military Hospital, Rawalpindi, Pakistan, from June to September 2023. METHODOLOGY: Patients admitted to the surgical ward with moderate to severe DFI were included by convenience sampling. Patients with severe sepsis, unstable haemodynamics, pressure injuries, and terminal illnesses were excluded. Demographic and clinical data of patients were noted down. LRINEC score was calculated on the day of admission. Final outcome (amputation or otherwise) was recorded on the 30th day the since the day of admission. RESULTS: Two hundred patients with moderate to severe DFI were included. The median age of patients was 56 years (IQR 49-66 years). The median duration of diabetes was 11 years (IQR 4 - 18.75 years). The median LRINEC score at admission was 6 (IQR 3-9). The majority of the patients (65.5%) had some other medical comorbid besides diabetes. Patients who had amputation due to DFI at 30 days post-admission had higher LRINEC scores on admission as compared to those patients who did not have amputation (Median 8 vs. 2, p <0.001). The cut-off point of LRINEC score ≥6.5 at admission had sensitivity of 74% and specificity of 94% in predicting amputation. CONCLUSION: The LRINEC score may be used as an objective scoring system to predict the risk of amputation in patients with moderate to severe DFI in indoor clinical settings. KEY WORDS: Diabetic foot, LRINEC score, Limb loss, Necrotising fasciitis.

There is shortage of organs, including kidneys, worldwide. Along with deceased kidney transplantation, there is a significant rise in live kidney donation. The prevalence of prediabetes (PD), including impaired fasting glucose and impaired glucose tolerance, is on the rise across the globe. Transplant teams frequently come across prediabetic kidney donors for evaluation. Prediabetics are at risk of diabetes, chronic kidney disease, cardiovascular events, stroke, neuropathy, retinopathy, dementia, depression and nonalcoholic liver disease along with increased risk of all-cause mortality. Unfortunately, most of the studies done in prediabetic kidney donors are retrospective in nature and have a short follow up period. There is lack of prospective long-term studies to know about the real risk of complications after donation. Furthermore, there are variations in recommendations from various guidelines across the globe for donations in prediabetics, leading to more confusion among clinicians. This increases the responsibility of transplant teams to take appropriate decisions in the best interest of both donors and recipients. This review focuses on pathophysiological changes of PD in kidneys, potential complications of PD, other risk factors for development of type 2 diabetes, a review of guidelines for kidney donation, the potential role of diabetes risk score and calculator in kidney donors and the way forward for the evaluation and selection of prediabetic kidney donors.
RESUMEN
This article presents a novel real-time meta-material (MM) sensor based on a non-invasive method that operates in microwave frequency ranges at 8.524 GHz to measure blood glucose levels with quality factor 184 is designed and fabricated. A cross enclosed between two square shapes produces a strong interaction between glucose samples and electromagnetic waves. In this study, 5 were tested noninvasively using the proposed glucose resonant sensor with a range of glucose-level changes from 50 to 130 mg/dL. For this range of glucose-level changes, the frequency detection resolution is 5.06 MHz/(mg/dL), respectively. Despite simulations, fabrication procedures (F.P.) have been carried out for more precise result verification. For the purpose of qualitative analysis, the proposed MM sensor is considered a viable candidate for determining glucose levels.
RESUMEN
Introduction The transperineal (TP) approach for prostate biopsy offers advantages such as a low risk of infection, the ability to target lesions in difficult locations, and a rapid acquisition of proficiency. This prospective clinical audit aims to evaluate the outcomes and patient experiences of TP prostate biopsies performed by a new operator to determine the feasibility of adopting the TP biopsy as the primary method for prostate evaluations. Methods The study included all patients who underwent a TP prostate biopsy from August 1 to September 30, 2022, at Dorset County Hospital National Health Service Foundation Trust. The operator, a member of the urology team, had recently begun performing these biopsies independently after completing a four-month supervised training program and receiving approval from two consulting trainers. The biopsy technique was evaluated based on diagnostic yield and patient experience, comparing pre-procedure imaging results with histology reports and analyzing patient-completed questionnaires. Results Among the 42 patients, the cancer detection rate was 79%. The highest core positivity rate was 100% in two patients (5%), with 90% in 11 patients (26%). Of the patients, 57% showed complete agreement between magnetic resonance imaging findings and histology. A questionnaire assessing patient experience received a 64% response rate. The most common pain score reported was 2 (on a scale of 0-10), noted in 25% of patients. Most reported mild lower urinary tract symptoms (88%) and mild hematuria (85%). Of the patients, 44% rated their overall satisfaction as 10 (on a scale of 0-10), and no urinary tract infections were reported. Conclusion The findings support the adoption of TP biopsy as the primary method for prostate biopsies due to its short learning curve, high diagnostic yield, and favorable patient satisfaction. Training for new operators should be encouraged to achieve this goal.
RESUMEN
Deceased donor kidney transplantation (DDKT) is common in high income Western countries with high transplantation rates. However, the utilization of deceased organs is suboptimal in Asia, due to a multitude of factors. Coherent policies are integral to the development of DDKT programs and deterrence of commercialization, but most are still at an infancy and formative stage in Asia. This review article identifies the glass ceiling effects of social, cultural, religious, political, and technical factors hampering the progress of DDKT in Asia. Additionally, it reviews the history of policy development in different countries and describes their idiosyncratic barriers and challenges. Lastly, it discusses innovative policy measures that can be undertaken to proliferate DDKT practice and curtail commercialization. The long-term ideal is to achieve regional equity and self-sufficiency, through a shared ethos of social and ethical responsibility that transcends and resonates with the different segments of the Asian community.
RESUMEN
Patent foramen ovale (PFO) is a flaplike opening in the fossa ovalis; between the septum primum and secundum. It is highly prevalent with approximately 25% of the population having a PFO. It is usually asymptomatic but can rarely cause paradoxical embolism leading to stroke and/or significant right to left shunting causing hypoxia. The complications of PFO closure with a percutaneous device include embolization, cardiac perforation, and thrombosis. These are all early complications. We describe the case of a patient with a history of PFO closure who had device thrombosis 3 years after implantation. Management includes anticoagulation with warfarin. Repeat cardiac imaging to document the resolution of thrombosis is recommended.
RESUMEN
Background: This retrospective study analyzed factors influencing all-cause inpatient mortality in 80,930 adult patients (2016-2020) with diffuse large B cell lymphoma using the National Inpatient Sample database. Methods: Utilizing ICD-10 codes, patients were identified, and statistical analysis was conducted using STATA. Fisher's exact and Student's t tests compared proportions and variables, multivariate logistic regression examined mortality predictors, and a 5-year longitudinal analysis identified mortality and resource utilization trends. Results: The inpatient mortality rate was found to be 6.56% with a mean age of 67.99 years. Several hospital- and patient-level factors including specific comorbidities such as congestive heart failure, atrial fibrillation, acute kidney injury, chronic obstructive pulmonary disease, liver failure, pancytopenia, tumor lysis syndrome, and severe protein-calorie malnutrition were independently associated with inpatient mortality. Hospitalization costs showed an increasing trend, impacting the overall population and survivors. Conclusion: These insights may refine risk assessment, treatment selection, and interventions.
RESUMEN
Designing non-precious catalysts to synergistically achieve a facilitated exposure of abundant active sites is highly desired but remains a significant challenge. Herein, a hetero-structured catalyst CoP-Co supported on porous g-C3N4 nanosheets (CoP-Co/CN-I) was prepared by pyrolysis and P-inducing strategy. The optimal catalyst achieves a turnover frequency (TOF) of 26 min-1 at room temperature and the apparent activation energy (Ea) is 35.5 kJ·mol-1. The catalytic activity is ranked top among the non-precious metal phosphides or the other supports. Meanwhile, the catalytic activity has no significant decrease even after 5 cycles. The CoP/Co interfaces provide richly exposed active sites, optimize hydrogen/water absorption free energy via electronic coupling, and thus improve the catalytic activity. The experimental results reveal that the CoP/Co heterojunction improves the catalytic activity due to the construction of dual-active sites. This research facilitates the innovative construction of non-noble metal catalysts to meet industrial demand for heterogeneous catalysis.
RESUMEN
OBJECTIVE: To find the effectiveness of distal sodium channel blocks in managing lumbosacral radicular syndrome. STUDY DESIGN: Open-labelled, non-randomised, single-group, prospective, pilot study. Place and Duration of the Study: Pain Clinic of Armed Forces Institute of Rehabilitation Medicine (AFIRM) Rawalpindi, Pakistan, from January to June 2022. METHODOLOGY: Patients having low back pain radiating to L5/S1/both dermatomes with severity of numerical rating scale (NRS) score of more than 4/10 were included. Straight leg raise (SLR) and NRS score were noted down at baseline and at 30 minutes, 24 hours, 1 week, and 4 weeks post-distal sodium channel block (DSCB). DSCB was performed at beta 1, 2, 3, and 5 portals using 2 ml of 2% injection plain lignocaine + 1 ml (40 mg) injection triamcinolone + 7 ml distilled water. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) 21. RESULTS: Out of 50 patients, 24 (48%) were females and 26 (52%) were males. No serious procedural complications were noted. Post-DSCB, follow-up was done for 4 weeks. A significant fall in NRS and an increase in SLR score were observed at every visit. Results were statistically significant (p<0.001) when mean NRS and SLR scores at every follow-up were compared for pre- and post-DSCBs. CONCLUSION: DSCB reduced pain and improved SLR in patients even at 4 weeks of follow-up. Advantages included immediate pain relief, easy to perform as outdoor procedure, cost-effective and a time buying alternative procedure allowing for the analgesic effect of medicine to kick in. KEY WORDS: Radiculopathy, Low-back pain, Epidural spinal injection, Sciatica, Pain management, Distal sodium channel blocks.

This study aimed to describe the spectrum of the results of neuromuscular electrodiagnostic investigations performed by age and pathology in paediatric patients. This retrospective observational study took place from January 2019 to December 2021. Electrodiagnostic records of paediatric patients (birth to 15 years) were referred to the electromyography (EMG) laboratory for EMG and nerve conduction study (NCS). Electrodiagnostic and demographic data were collected. Among these, 151 (56%) were males and 118 (44%) were females. Forty-four percent tests came out to be normal and 151(56%) tests revealed electrophysiological abnormality. Peripheral nerve neuropathy (n = 39, 14.5%), polyneuropathy (n = 35, 13%) and myopathy (n = 28, 10%) were the most common electrophysiological diagnoses. The electrodiagnostic test helps in differentiating the aetiologies, thus guiding the subsequent work-up logically in the paediatric population.
