Inter-Semispinalis Plane Block Versus General Anesthesia for Postoperative Analgesia in Posterior Cervical Spine Surgery: A Randomized Controlled Trial.

Background: Postoperative pain management is crucial for improving patient outcomes following posterior cervical spine surgery. Opioids are effective but carry a risk of respiratory depression. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used but may not provide adequate pain relief and have potential complications. The inter-semispinalis plane (ISPB) block is a novel technique for postoperative analgesia in cervical spine surgery. Objectives: This study aims to evaluate and compare the efficacy of the ISPB with general anesthesia in terms of analgesia, postoperative Visual Analog Scale (VAS) pain scores, patient-surgeon satisfaction levels, and the occurrence of postoperative complications. Methods: This double-blind, randomized controlled trial was blinded to both the patient and the assessor. Fifty adult patients (18 - 60 years old) undergoing elective posterior cervical spine surgery were enrolled. The participants were divided into 2 groups: The ISPB group (receiving bilateral ultrasound-guided ISPB at the C5 level) and the control group (receiving general anesthesia only), with each group comprising 25 patients. The study assessed intraoperative fentanyl use, postoperative VAS pain levels, the need for rescue analgesia, and complications. Results: The ISPB group showed significantly lower intraoperative fentanyl consumption (median 100 vs. 100 - 150 µg, P = 0.022) and lower postoperative pain scores at 1, 8, 12, and 48 hours (P = 0.016, 0.009, 0.005, 0.016). Additionally, the ISPB group required less postoperative pethidine (20% vs. 64%, P = 0.002) and had a longer delay before requesting pethidine (hazard ratio 0.215, P = 0.001). Surgeon satisfaction was significantly higher in the ISPB group (P = 0.003). These results suggest that the ISPB can effectively reduce pain and analgesic requirements. Conclusions: The ISPB is an effective analgesic technique for posterior cervical spine surgery, reducing opioid consumption, providing better pain control, and enhancing surgeon satisfaction without increasing complications. This approach has the potential to improve postoperative care and patient outcomes in this surgical population.

Prevalence of anemia and associated factors among pregnant women at Hargeisa Group Hospital, Somaliland.

BACKGROUND: Anemia remains a major global public health issue, affecting around 24.8% of the world's population in both developing and developed countries. Pregnant women in developing countries are particularly susceptible, with 38.2% affected worldwide. Anemia is also a major contributor to maternal mortality, with 510,000 maternal deaths globally, of which 20% occur in developing countries and are related to anemia. Iron deficiency anemia is the most prevalent form, impacting 1.3 to 2.2 billion individuals, with 50% being women of reproductive age. AIM: This study aimed to assess the prevalence and associated factors of anemia in pregnant women attending antenatal care (ANC) at Hargeisa Group Hospital (HGH), Somaliland. METHODS: A cross-sectional study included 360 pregnant women, who sought ANC at HGH from July 15 to August 6, 2023. The study subjects were selected using systematic random sampling. Data were collected through structured questionnaires and participants' current medical charts, including hemoglobin levels. Data analysis was performed using SPSS software (version 20). RESULTS: The study revealed an overall prevalence of anemia among pregnant women at 50.6% (95% CI: 45.40 - 55.72%). Anemia severity was categorized as mild (33.0%), moderate (54.9%), and severe (12.1%). Factors statistically associated with anemia included gestational age in the third trimester (AOR = 3.248, 95% CI: 1.491-7.074), lack of ANC visits (AOR = 6.828, 95% CI: 1.966-23.721), and absence of iron supplementation (AOR = 29.588, 95% CI: 2.922-299.713). Notably, a higher consumption of meat per week was associated with a reduced risk of anemia (AOR = 0.198, 95% CI: 0.104-0.379). CONCLUSION: The study underscores the severity of anemia in pregnant women within the range considered as severe public health problem by WHO. It is crucial to emphasize effective prenatal care, improve dietary practices, and promote the provision of iron supplements. Enhanced maternal education on Anemia during ANC visits has the potential to reduce Anemia prevalence and mitigate adverse maternal and neonatal outcomes.

The use of dienogest in treatment of symptomatic adenomyosis: a systematic review and meta-analysis.

Adenomyosis is a gynaecological problem that impacts women's quality of life by causing dysmenorrhea, chronic pelvic pain, and menorrhagia. The search continues for the best medical treatment for symptomatic adenomyosis. This systematic review and meta-analysis investigated the role of dienogest, an oral progestin, in reducing pain and bleeding associated with adenomyosis. Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, Scopus, and Web of Science were searched in January 2024. The primary outcome was pain scores for dysmenorrhea, whereas secondary outcomes were chronic pelvic pain (CPP), uterine volume (UV), and menorrhagia. One comparison was performed comparing outcomes in symptomatic adenomyosis before and after treatment with dienogest. Pooled analysis of included studies reported a statistically significant reduction of dysmenorrhea pain score after dienogest treatment (mean difference -5.86 cm on a 10-cm visual analogue scale, 95% CI -7.20 to -4.53, I2 = 97%). Regarding chronic pelvic pain, a meta-analysis of included studies showed a significant decline in pain after treatment (standardized mean difference -2.37, 95% CI -2.89 to -1.86, I2 = 60%). However, uterine volume did not differ significantly after treatment (mean difference -4.65 cm3, 95% CI -43.22 to 33.91). Menorrhagia was improved significantly after treatment (Peto odds ratio 0.07, 95% CI 0.03 to 0.18). In conclusion, dienogest seems to be effective in controlling painful symptoms and uterine bleeding in women with adenomyosis at short and long-term therapy.

Studying the accessibility of healthcare services for cancer patients in Khartoum state amid the COVID-19 pandemic.

Objectives: This study aims to assess cancer patients' accessibility to healthcare services and perceived barriers during the COVID-19 pandemic in Khartoum state, aiming to explore the consequent impact on cancer patients. It also aims to determine the coping strategies used by patients to overcome these barriers. Study design: This is a retrospective analytical cross-sectional study. Methods: Data were collected from August 2020 to March 2021, with a sample size of 316 cancer patients. Systemic random sampling and SPSS version 25 were utilized for data collection and analysis. Results: The study found that 55.7 % of the surveyed cancer patients had experienced disruptions in accessing essential cancer healthcare services during the lockdown. The study identified the most common cancers as breast (19.7 %), gastrointestinal (19 %), and ovarian (11 %). Notable barriers included governmental travel restrictions (51.6 %), outpatient service closures (41.8 %), and high costs (27.8 %). Additionally, delayed treatment was directly associated with a 33.3 % fatality rate among the participants. Conclusions: This study highlights the considerable negative impact of the COVID-19 lockdown on cancer care in Sudan. Recommendations include a focus on telemedicine as an alternative form of patient consultation, the expansion of health insurance schemes to encompass cancer treatments, and strengthening healthcare infrastructure to facilitate cancer care during crises.

Mothers' evaluations of fathers' contributions to raising children with autism spectrum disorder in the United Arab Emirates.

BACKGROUND: Autism spectrum disorder (ASD) is a lifelong neurological condition which results in social skill deficits, communication difficulties, and restrictive and repetitive behaviour. The difficulties associated with parenting children with ASD have been studied extensively, mainly from the perspectives of mothers. The extent of involvement of fathers in the raising of children with ASD has received limited scholarly attention, especially in non-Western contexts such as the United Arab Emirates. OBJECTIVES: This study asked mothers to evaluate the involvement of fathers in the development of children with ASD. METHODS: In all, 240 mothers completed the Fathers' Involvement in Development and Rehabilitation Scale, designed based on a review of literature on the construct of involvement, namely attitude, participation in training, and support domains. The data were subjected to computation of mean scores, multivariate analysis of variance, hierarchical regression, and moderation analyses. RESULTS: The results suggested that fathers held positive attitudes and provided substantial support to their children with ASD. However, mothers were ambivalent regarding the participation of fathers in training to support the development of their children. Differences were also observed between participants according to marital status, location, child gender, and ASD severity. CONCLUSION: Recommendations for targeted training for fathers and other study implications are discussed.

Color and flexural properties of nanoparticles-modified denture base resin: An in vitro comparative study.

Objectives: Reinforcement of polymethylmethacrylate (PMMA) denture base resins (DBRs) with inorganic fillers with superior properties and accepted aesthetics are favored and still a big dilemma. This study was undertaken to evaluate the color change, flexural strength, and modulus of elasticity of heat-polymerized DBR material modified with silver nanoparticles (AgNPs) and zirconium dioxide nanoparticles (ZNPs). Methods: Sixty acrylic specimens (30/color test, 30/flexural properties) were fabricated and divided according to nanoparticles type and addition into 3 groups (n = 10). Group-I; unmodified specimens, Group-II; modified specimens with 0.5wt% AgNPs (PMMA/AgNPs), and Group-III; modified specimens with 7.5wt% ZNPs (PMMA/ZNPs). Disc-shape (20 × 3 mm) and bar-shape (65 × 10 × 2.5 mm) specimens were fabricated for color and flexural properties, respectively. The spectrophotometer was used for evaluation of the color change (∆E). The flexural strength and elastic modulus evaluation was carried out using a 3-point bending test (5 mm/min). Tukey's post hoc and one-way ANOVA were used to analyze the data at a significant level P ≤ 0.05. Results: PMMA/AgNPs group exhibited a significant increase in color change when compared with PMMA/ZNPs. PMMA/ZNPs showed significantly the highest flexural strength value when compared with unmodified and PMMA/AgNPs groups (P < 0.001), however, there was an absence of significant differences in terms of flexural strength values between PMMA/AgNPs and unmodified groups (P > 0.05). PMMA/AgNPs insignificantly increased its modulus of elasticity strength (P = 0.09410) while PMMA/ZNPs significantly increased its modulus of elasticity strength (P = 0.00396). Conclusion: The AgNPs and ZNPs addition to PMMA increased the color change and AgNPs change the color of DBRs. The flexural attributes of DBRs have been increased by ZNPs.

Adipokine (adiponectin-rs1501299) Gene Variant and Patient Characteristics in Relation to Metabolic-associated Fatty Liver Disease.

Background: Several genetic and metabolic variables, most notably the variation in the adipokine gene rs1501298, have been linked to metabolic-associated fatty liver disease etiopathogenesis (MAFLD). Liver biopsy, the gold standard for diagnosing MAFLD, is an invasive procedure; therefore, alternative diagnostic methods are required. Consequently, the integration of these metabolic variables with some of the patients' characteristics may facilitate the development of noninvasive diagnostic methods that aid in the early detection of MAFLD, identification of at-risk individuals and planning of management strategies. Methods: This study included 224 Egyptians (107 healthy individuals and 117 MAFLD patients). Age, sex, BMI, clinical and laboratory characteristics, and rs1501299 adipokine gene polymorphisms were examined. The rs1501299 variant, insulin resistance, hypertension, obesity, blood pressure, lipid profile, hemoglobin A1C level, and hepatic fibrosis predictors were evaluated for MAFLD risk. The feasibility and effectiveness of developing non-invasive MAFLD diagnostic models will be investigated. Results: The +276G/T (rs1501299) polymorphism (GG vs GT/TT) was linked with MAFLD (OR: 0.43, CI: 0.26-0.69, P = 0.002). The GG variants had lower MAFLD rates than those of the GT and TT variants. In addition to altered lipid profiles, patients with MAFLD showed increased gamma-glutamyl transferase levels (GGT: 56 IU/L vs. 36 IU/L). Genetic diversity also affects the accuracy of hepatic fibrosis and steatosis prediction. Hepatic fibrosis and steatosis predictors had receiver operating characteristic (ROC) AUCs of 0.529%, 0.846%, and 0.700-0.825%, respectively. We examined a diagnostic model based on these variables and demonstrated its effectiveness. Conclusion: The Adipokine variant rs1501299 increased the risk of MAFLD. Identifying and genotyping this variation and other metabolic variables allow for a noninvasive diagnostic model for early MAFLD diagnosis and identification of those at risk. This study illuminates the prevention and management of MAFLD. Further research with more participants is needed to verify these models and to prove their MAFLD diagnostic efficacy.

The effect of NHFOV on hemodynamics in mild and moderately preterm neonates: a randomized clinical trial.

The aim of this study is to study cardio-respiratory effects of nasal high-frequency oscillatory ventilation (NHFOV) vs. NCPAP as an initial mode of ventilation in moderate-late-preterm infants. A randomized controlled trial was conducted in NICU of Alexandria University Maternity Hospital (AUMH). One-hundred late-moderate-preterm infants were randomly assigned to either NHFOV-group (n = 50) or NCPAP-group (n = 50). For both groups, functional echocardiography was performed in the first 24 h to detect hemodynamic changes and respiratory outcome was monitored throughout the hospital stay. The main outcomes were hemodynamic measurements and myocardial function using functional echocardiography of those infants along with the respiratory outcome and complications. Kaplan-Meier survival plot was used representing time course of NCPAP and NHFOV failure. Left ventricular output values were not significantly different in both groups with median 202 ml/kg /min and IQR (176-275) in NCPAP-group and 226 ml/kg/min with IQR (181-286) in NHFOV group. Nevertheless, ejection fraction and fractional shortening were significantly higher in NHFOV-group with P 0.001. The time to weaning, the time to reach 30%-FIO2, the need for invasive ventilation, oxygen support duration, and maximal-FIO2 were significantly more in NCAPAP group.     Conclusion: NHFOV is an effective and promising tool of non-invasive-ventilation which can be used as a primary modality of respiratory support in preterm infants with variable forms of respiratory distress syndrome without causing detrimental effect on hemodynamics or significant respiratory complications.     Trial registration: NCT05706428 (registered on January 21, 2023). What is Known: • NHFOV might be beneficial as a secondary mode of ventilation and might have an impact on hemodynamics. What is New: • NHFOV can be used as an initial mode of ventilation with CDP beyond the reported pressure limits of CPAP without causing neither CO2 retention nor adverse hemodynamic consequences.

Knowledge, perceived needs of continuous professional's development, and associated factors among healthcare workers in East Ethiopia: a multi-health facility-based cross-sectional study.

BACKGROUND: The Ethiopian Ministry of Health (EMOH) has recently introduced a Continuous Professional Development (CPD) program for healthcare workers to ensure they maintain the necessary competencies to meet the community's health needs. However, there is limited information on healthcare workers' knowledge and perceived need for CPD. This study aims to assess healthcare workers' CPD knowledge, perceived needs, and factors associated with these in eastern Ethiopia. METHODS: A health facility-based cross-sectional quantitative study was conducted from September 1, 2022, to October 30, 2022. Health facilities and study participants were selected using a simple random sampling technique. A total of 731 healthcare professionals were randomly selected. Data was collected using a self-administered questionnaire developed from national CPD guidelines. Data analysis was performed using the STATA statistical package version 14. A logistic regression model was used to assess the association between predictors and the outcome variable. Adjusted odds ratios with 95% confidence intervals were calculated to determine the strength of the association. A p-value < 0.05 was considered statistically significant. RESULTS: In this study, 731 healthcare workers participated. Among them, 65.80% (95% CI: 62.35%, 69.24%) had knowledge of CPD, and 79.48% (CI95% 76.54, 82.41) expressed a strong perceived need for CPD. Female healthcare workers [AOR: 0.54 (95% CI: 0.37, 0.78)] and lack of internet access [AOR: 0.68 (95% CI: 0.47-0.97)] were predictors of knowledge of CPD. Age above 35 [AOR: 0.39 (95% CI: 0.17, 0.91)] and being female [AOR: 0.59 (95% CI: 0.40-0.87)] were predictors of a strong perceived need for CPD. CONCLUSION: The study found that there was a low level of knowledge about Continuing Professional Development among healthcare workers. The perceived needs of healthcare workers varied. It is important for health sectors and stakeholders to prioritize developing strategies that address knowledge gaps, particularly among female healthcare workers, improve access to the Internet for CPD resources, and address the diverse needs of professionals for effective CPD implementation.

The critical impacts of cytokine storms in respiratory disorders.

Cytokine storm (CS) refers to the spontaneous dysregulated and hyper-activated inflammatory reaction occurring in various clinical conditions, ranging from microbial infection to end-stage organ failure. Recently the novel coronavirus involved in COVID-19 (Coronavirus disease-19) caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) has been associated with the pathological phenomenon of CS in critically ill patients. Furthermore, critically ill patients suffering from CS are likely to have a grave prognosis and a higher case fatality rate. Pathologically CS is manifested as hyper-immune activation and is clinically manifested as multiple organ failure. An in-depth understanding of the etiology of CS will enable the discovery of not just disease risk factors of CS but also therapeutic approaches to modulate the immune response and improve outcomes in patients with respiratory diseases having CS in the pathogenic pathway. Owing to the grave consequences of CS in various diseases, this phenomenon has attracted the attention of researchers and clinicians throughout the globe. So in the present manuscript, we have attempted to discuss CS and its ramifications in COVID-19 and other respiratory diseases, as well as prospective treatment approaches and biomarkers of the cytokine storm. Furthermore, we have attempted to provide in-depth insight into CS from both a prophylactic and therapeutic point of view. In addition, we have included recent findings of CS in respiratory diseases reported from different parts of the world, which are based on expert opinion, clinical case-control research, experimental research, and a case-controlled cohort approach.

Computer vision syndrome among Sudanese medical students: a growing medical issue in the digital world.

Computer vision syndrome (CVS) refers to a set of eye-related symptoms that arise from prolonged computer usage. A survey was conducted to investigate the demographic characteristics, factors contributing to, and preventive measures against CVS. Out of 159 participants, 31.0% experienced seven or more symptoms, indicating a notable prevalence. The study found no significant correlation between age or academic years and CVS occurrence (P values of 0.481 and 0.392, respectively). However, gender exhibited a statistically significant relationship, with females students showing a higher prevalence than males (P=0.018; τ=0.105*). Notably, the distance from the screen had a highly significant inverse correlation with CVS occurrence (P=0.000; τ=-0.207**), indicating that greater distance reduced the risk. Additionally, using a screen filter (P=0.000; τ=0.184**) and adjusting screen brightness (P=0.017; τ=0.101*) were associated with CVS occurrence. Among preventive measures, only the use of an anti-glare screen showed a significant association with reducing CVS risk (P=0.018; τ=-0.099*). Given these findings, raising awareness about CVS among medical students is recommended, especially as curricula in medical colleges evolve.

Healthcare workers' knowledge and risk perception regarding the first wave of COVID-19 in Khyber Pakhtunkhwa, Pakistan: an online cross-sectional survey.

Background: Increased COVID-19 transmission among the populace may be caused by healthcare workers (HCWs) who lack knowledge, awareness, and good preventive practices. Additionally, it may cause elevated stress levels, anxiety, poor medical judgement, and situational overestimation. Objectives: The present survey aimed to assess knowledge and risk perception regarding COVID-19 among HCWs in Khyber Pakhtunkhwa (KP), Pakistan. Methodology: A web-based online, pre-tested questionnaire comprising 26 items was circulated via social media in April 2020 amongst HCWs in major tertiary care facilities in KP. Results: The study's results, revealing both the commendable knowledge levels among HCWs about COVID-19 and their heightened risk perception, highlight the critical need for targeted interventions to address the potential impact on self-protective behaviour and mental health within this vital workforce. This insight is important for designing strategies that not only enhance HCWs' well-being but also ensure the continued effectiveness of healthcare delivery during pandemics. The percentage mean score (PMS) of COVID-19 knowledge was 85.14±10.82. Male HCWs and those with an age older than or equal to 32 years demonstrated a higher knowledge score (85.62±11.08; P=0.032 and 87.59±7.33, P=0.021, respectively). About 76% of HCWs feared contracting COVID-19. Nearly 82% of respondents were mentally preoccupied with the pandemic and also terrified of it. 'Of these, 81% were nurses, 87% had a job experience of 6-8 years and 54.45% were frontline workers. Feelings of panic and concern about the pandemic were found to be more in HCWs who were physicians above the age of 32, and who had 3-5 years of work experience. HCWs' overall risk perception was found to be significantly different between males (7.04±2.26) and females (8.01±1.97), job experience of 6-10 years (8.04±177) with 3-5 years and younger than or equal to 2 years job experience (7.18±2.43,6.93±2.22), respectively, and between frontline HCWs (7.50±2.10) and non-frontline HCWs (6.84±2.40). Conclusion: HCWs demonstrated good knowledge about COVID-19. As the risk perception of COVID-19 among HCWs is high, it can raise concerns about their self-protective behaviour, and mental health. These issues need to be addressed.

Macrophage activation syndrome in a Sudanese child: a case report from Sudan.

Introduction and importance: Macrophage activation syndrome (MAS) is a severe form of hemophagocytic lymphohistiocytosis that is frequently associated with either a flare-up of rheumatologic diseases, or infection and is characterized by intermittent fever, organomegaly, and multisystem dysfunction. Early diagnosis and treatment are crucial for outcome improvement. Case presentation: The authors present a 9-year-old male with systemic onset juvenile idiopathic arthritis who presented with fever, vomiting, and nose bleeding, as well as being jaundiced, and having hepatomegaly and ascites. Pancytopenia, hepatic dysfunction, and elevated ferritin levels were discovered, along with negative virological and immunological tests. He was given broad-spectrum antibiotics, and a high-dose steroid showed a good response, and he was discharged about a week later. Clinical discussion: It is hypothesized that decreased natural killer cells' function could lead to the inability to clear the infection, and subsequent lymphocytes-induced macrophages activation. Despite being beneficial in this case, steroids led to no improvement in other similar cases. Conclusion: MAS is a real life-threatening complication for patients with systemic Juvenile idiopathic arthritis (sJIA), and early diagnosis and prompt initial treatment can both offer a favourable result against such syndrome.

Echocardiographic right ventricular evaluation in cardiac surgery patients undergoing mitral valve reconstruction: a single center prospective observational study.

Background: Mitral valve (MV) regurgitation (MR) is the second most frequent indication for valvular surgery in Europe. Right ventricular (RV) dysfunction is a common finding after cardiac surgery and might persist for years. The RV-function after MV surgery has been controversially discussed. We therefore aimed to evaluate early RV-performance in patients undergoing MV surgery. Methods: Between 09/2020 and 06/2022, ninety-two patients presenting with MR undergoing MV surgery were consented and prospectively included for evaluation. Echocardiographic evaluation was performed one day before surgery, one week after surgery and three months later. Primary endpoints reported RV-function changes including tricuspid annular plane systolic excursion (TAPSE), RV systolic prime (S') and fractional area change (FAC). Secondary endpoints included stability of MV repair, changes in left ventricular functions and early mortality. Results: Mean patients' age was 59.1±11.4 years. Fifty-five (59.7%) patients were male. Most of patients presented with severe (n=88; 95.7%) MR. Mean systolic pulmonary artery pressure was 35.6±15.7 mmHg. Moderate or severe pulmonary arterial hypertension (PAH) was present in 60 (65.2%) patients. Patients underwent either isolated MV surgery (n=67; 72.8%) or combined with tricuspid valve surgery (n=25; 27.2%). Minimal invasive surgery was performed in 26.1% (n=24) of the patients. Postoperative short-term follow-up at 3 months reported RV-dysfunction in 44.5% (n=41) of the patients as indicated by reductions in TAPSE & RV S' from 21.2±4.7 to 14±3.3 mm (P<0.001) and from 14.7±4.3 to 9.7±2.8 cm/s (P<0.001) respectively. The FAC reduction from 42.9%±9.6% to 42.2%±9.9% was non-significant (P=0.593) and no need for redo mitral or tricuspid valve surgery was reported. Finally, the presence and severity of preoperative PAH played significant roles for the incidence of RV dysfunction, P=0.021 and P=0.047, respectively. Minimal invasive surgical procedure significantly reduced the incidence of postoperative RV-dysfunction (P=0.013). Conclusions: Study early results report a significant reduction of RV-function after MV surgery as measured by TAPSE, & RV S', even when the FAC remains unchanged. Even though, this finding has limited prognostic implications during an uneventful surgical course.

Therapeutic antibody engineering for efficient targeted degradation of membrane proteins in lysosomes.

Targeted degradation of pathological proteins is a promising approach to enhance the effectiveness of therapeutic monoclonal antibodies (mAbs) in cancer therapy. In this study, we demonstrate that this objective can be efficiently achieved by the grafting of mannose 6-phosphate analogues called AMFAs2 onto the therapeutic antibodies trastuzumab and cetuximab, both directed against membrane antigens. The grafting of AMFAs confers to these antibodies the novel property of being internalized via the mannose 6-phosphate receptor (M6PR) pathway. AMFA conjugation to these mAbs significantly increases their cellular uptake and leads to enhanced degradation of the target antigens in cancer cells. This results in a drastic inhibition of cancer cell proliferation compared to unconjugated mAbs, as demonstrated in various cancer cell lines, and an increased therapeutic efficacy in mouse and zebrafish xenografted models. These findings highlight the potential of this technology to improve therapeutic outcomes in cancer treatment.

Turn-on fluorescence of mirabegron for its sensitive detection in human plasma: Box-Behnken-Design for optimization.

Here, a novel fluorescence strategy was established for the detection of mirabegron (MBG) sensitively on the basis of hantzsch dihydropyridine synthesis. The developed method adopts turn-on fluorescence of MBG for the first time, permitting its selective determination in spiked human plasma at 486 nm after excitation at 410 nm. The developed method exhibited a good linear range from 0.5 µgmL-1 to 2.0 µgmL-1 with detection and quantification limits of 0.05 and 0.2 (µgmL-1), respectively. The profitable applicability of the developed method in spiked human plasma samples was demonstrated, achieving limit of detection below the previously levels reported by spectroscopic methods, allowing application of the developed method for selective determination of MBG in its tablets and spiked human plasma samples with good recovery.

Subscapularis pyomyositis, a rare cause of shoulder pain, in a patient without apparent risk factors: A case report.

INTRODUCTION: Pyomyositis, previously tropical, now seen more in temperate zones, particularly in those with HIV, cancer, or diabetes. Even healthy individuals, like athletes, can get it post-exercise or minor injuries. Our patient, in a desert-like area, adds an interesting aspect. Diagnosing is challenging due to deep tissue occurrence and subtle symptoms, leading to delayed detection and higher risks of morbidity. PRESENTATION OF CASE: A 45-year-old female patient presented with acute left shoulder pain and functional impairment, exacerbated by movement. Clinical examination revealed tenderness upon deep palpation in the left upper posterior thoracic region and restricted range of motion of the affected shoulder. DISCUSSION: Initial assessments at medical facilities suggested musculoskeletal strain and lower cervical disc prolapse despite normal X-ray results. MRI scans confirmed a developing abscess in the left subscapularis muscle, with intraoperative findings revealing extensive purulent fluid and necrotic tissue. Four surgeries drained the abscess and treated fat necrosis, with tailored antibiotics administered. Subsequent arthroscopy showed fibrous tissue, swelling, and inflammation. At the 3-month check-up, she had fully recovered, experiencing no pain or complications, and had almost regained full range of motion. CONCLUSION: Shoulder pyomyositis presents diagnostic challenges, causing delayed treatment. This case highlights the importance of considering pyomyositis in severe shoulder pain cases, even without typical risk factors or inconclusive X-rays. Timely recognition, surgical drainage, tailored antibiotics, and physical therapy are crucial. An interdisciplinary approach with orthopaedic surgery, infectious disease specialists, radiology, and physical therapy is vital for comprehensive management, improving outcomes, and reducing complications.

Comparison of transient elastography and shear wave elastography in patients with MAFLD: A single-center experience.

BACKGROUND: Metabolic-associated fatty liver disease and liver fibrosis are intimately linked to insulin resistance, type 2 diabetes, obesity, and metabolic syndrome. Transient elastography (TE) and point shear wave elastography (pSWE) were used to measure liver stiffness in patients who met the ultrasound criteria for steatotic liver diseases (SLD). This study compared two methods for estimating liver stiffness in patients with SLD, which in turn correlated with liver fibrosis. METHOD: Ultrasound B-mode imaging was used to identify SLD. In total, 250 MAFLD patients were recruited. Patient characteristics, laboratory investigations, and liver stiffness measurements using TE and pSWE were assessed on the same day. RESULTS: In the study, 56.0% of the patients were male, with a mean age of 41.5 ± 10.7 years. The correlation between TE and pSWE was significant (Spearman's r = 0.867*, p < .001). The Bland-Altman Plot analysis confirmed this, with 97.5% of variations in LSM falling within 95% agreement ranges. Cohen's κ was used to assess the agreement between TE and pSWE fibrosis stages, showing almost perfect agreement (83.5% kappa agreement) and a strong association between pSWE and TE in the assessment fibrosis stages. CONCLUSION: In patients with MAFLD, TE, and SWE are reliable methods for measuring liver stiffness and can be used as non-invasive screening tools for the assessment of fibrosis in SLD.
