The widespread use of pesticides, particularly in combinations, has resulted in enhanced hazardous health effects. However, little is known about their molecular mechanism of interactions. The aim of this study was to assess the neurotoxicity effect of pesticides in mixtures by adopting a 3D in vitro developed neurospheroid model, followed by treatment by increased concentrations of pesticides for 24 h and analysis by a shotgun proteomic-based approach with high-resolution tandem mass spectrometry. Three proteins, namely, glyceraldehyde-3-phosphate-dehydrogenase (GAPDH), α-enolase, and phosphoglycerate-kinase-1, were selected as key targets in the metabolic process. Only high doses of pesticides mitigated cell-density proliferation with the occurrence of apoptotic cells, which unlikely makes any neurological alterations in environmental regulatory exposures. The proteomic analysis showed that majority of altered proteins were implicated in cell metabolism. De novo peptide sequencing revealed ion losses and adduct formation, namely, a trityl-post-translational modification in the active site of 201-GAPDH protein. The study also highlights the plausible role of pyrethroids to be implicated in the deleterious effects of pesticides in a mixture. To the best of our knowledge, our finding is the first in toxicoproteomics to deeply elucidate pesticides' molecular interactions and their ability to adduct proteins as a pivotal role in the neurotoxicity mechanism.

Study Objective: We wished to determine whether the addition of magnesium sulfate (MgSO 4 ) or lidocaine to diclofenac could improve the analgesic efficacy in emergency department (ED) patients with acute renal colic., Methods: In this prospective, double-blinded, randomized controlled trial of patients aged 18 to 65 years with suspected acute renal colic, we randomized them to receive 75 mg intramuscular (IM) diclofenac and then intravenous (IV) MgSO 4, lidocaine, or saline solution control. Subjects reported their pain using a numerical rating scale (NRS) before drug administration and then 5, 10, 20, 30, 60, and 90 minutes afterwards. Our primary outcome was the proportion of participants achieving at least a 50% reduction in the NRS score 30 minutes after drug administration., Results: We enrolled 280 patients in each group. A 50% or greater reduction in the NRS score at 30 minutes occurred in 227 (81.7%) patients in the MgSO 4 group, 204 (72.9%) in the lidocaine group, and 201 (71.8%) in the control group, with significant differences between MgSO 4 and lidocaine (8.8%, 95% confidence interval [CI] [1.89 to 15.7], P=.013) and between MgSO 4 and control (9.9%, 95% CI [2.95 to 16.84], P=.004). Despite this, differences between all groups at every time point were below the accepted 1.3 threshold for clinical importance. There were no observed differences between groups in the frequency of rescue analgesics and return visits to the ED for renal colic. There were more adverse events, although minor, in the MgSO 4 group., Conclusion: Adding intravenous MgSO 4 , but not lidocaine, to IM diclofenac offered superior pain relief but at levels below accepted thresholds for clinical importance., (Copyright © 2024 American College of Emergency Physicians.

Introduction: Recent FDA approval of difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase for the prevention of neuroblastoma in children, has renewed interest in this medication for the prevention of other cancers including keratinocyte carcinomas (KCs). It has been investigated for cancer chemoprevention, including neoplasms of the colon, breast, and prostate., Methods: We assessed the current body of literature that determines DFMO efficacy and safety in non-melanoma skin cancer prevention. A systematic search of PubMed Central, and Web of Sciences was performed., Results: In this analysis, 12 studies were included evaluating 1618 patients. Most patients were Caucasian 90% (1452/1618) with a mean age of 61 years, and 73% (1214/1618) had previously been diagnosed with KC. For oral DFMO, reduction in KC was significant in 24% (291/1214) of patients. Nonsignificant reduction was observed in 17% (207/1214) of patients. The remaining studies, representing 59% (716/1214) of patients explored DFMO's pharmacological/biological effects without elucidating its direct impact on KC. Topical DFMO shows modest efficacy in reducing the number of actinic keratosis (AK), as indicated in 4 studies representing 38.12% (154/404) of patients. For patients taking the oral eflornithine, the most frequently reported adverse events included reversible ototoxicity (11% of patients) gastrointestinal disturbances (10.39%). For the topical DFMO transient local cutaneous eruptions were common impacting 28.76% (111/386) of patients., Conclusion: Current evidence highlights the lack of conclusive data supporting the efficacy of oral DFMO, making it difficult to recommend its use. Conversely, topical DFMO demonstrates more promising outcomes in preventing AKs, presenting a potentially useful alternative in select patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

APX proteins are H 2 O 2 -scavenging enzymes induced during oxidative stress. In the first part of this study, we provided an extensive knowledge on the APX family of Triticum durum, TdAPX and their related TdAPX-R, via the genome wide analysis. The outcomes showed that these proteins are clustered into four major subgroups. Furthermore, the exon-intron structure and the synteny analyses revealed that during evolution the genes TdAPX and TdAPX-R are relatively conserved. Besides, during their evolution, these genes underwent purifying selection pressure and were duplicated in segmental. In parallel, the analysis of the conserved motifs and the multiple sequence alignment demonstrated that the residues involved in the active sites, heme- and cations-binding are conserved only in TdAPX proteins. Following the RNA-seq data and the regulatory elements analyses, we focused in the second part of this study on the functional characterization of TdAPX7B-2. The qRT-PCR data showed the upregulation of TdAPX7B-2 essentially in leaves of durum wheat exposed to salt, cold, drought, metals and ABA treatments. The tolerance phenotype of the TdAPX7B-2-expressing Arabidopsis lines to salt, direct-induced oxidative stress and heavy metals was manifested by the development of root system, proline accumulation and induction of the antioxidant CAT, SOD and POD enzymes to maintain the non-toxic H 2 O 2 levels. Likewise, the response to salt stress and direct-oxidative stress of the transgenic lines was accompanied mainly by the induction of AtNCED3, AtRD29A/B and AtERD1., Competing Interests: Declarations.

Desmoid tumors, also known as deep fibromatosis or desmoid-type fibromatosis, represent a rare subset of deep fibromatoses. It is a locally aggressive tumor, with no specific symptoms, and no metastatic potential. We report a case of a 38-year-old male patient with an abdominal mass. Radiological findings showed 2 tumors, the first was a solid inguinal mass of the left lateral iliac pedicle, and the second was a giant cystic mass in the abdominal cavity. An elective explorative laparotomy was performed to remove the 2 masses. Histopathological examination confirmed the desmoid tumor diagnosis of both lesions., (© 2024 The Authors.

Rectal migration of an intrauterine device (IUD) is a rare but potentially serious complication requiring prompt diagnosis and management. We present a rare case of rectal migration of an intrauterine device (IUD) in a 26-year-old female, highlighting the clinical presentation, diagnostic evaluation, laparoscopic removal, and postoperative outcomes. This case emphasizes the critical importance of vigilant monitoring, early intervention, and close follow-up in managing IUD migration to ensure optimal patient outcomes. Timely recognition and intervention resulted in successful symptom resolution and a favorable long-term prognosis., (© 2024 The Authors.

Plexiform neurofibroma is characterized by diffuse intraneural neoplastic overgrowth involving a long nerve segment, with tortuous expansion of its branches. It is a hallmark of Neurofibromatosis Type 1 (NF1). We report the case of a 36-year-old man with a known diagnosis of NF1, who was admitted for chronic posterior cervical pain and cervicobrachial neuralgia. MRI findings were consistent with plexiform neurofibromas. This case underscores the importance for radiologists to consider these tumors as a potential cause of cervicobrachial neuralgia in patients with NF1., (© 2024 The Authors.

Estuaries and lagoons are characterized by fluctuating salinity and significant amounts of microplastics (MPs) and are increasingly subjected to various anthropogenic pressures. We investigated whether the accumulation of MPs in the gills of fish inhabiting these fragile ecosystems alters osmoregulation and, consequently, their ability to tolerate fluctuating salinity. The effects of a 15-day exposure to an environmentally relevant concentration (20 μg/L) of spherical polystyrene microplastics (PS-MPs) with a diameter of 5 μm were assessed in the Mediterranean killifish Aphanius fasciatus, focusing on tissue and gene expression changes related to factors of paracellular and transcellular permeability of the gill epithelium during the transition from seawater to freshwater. Our results revealed that PS-MPs indirectly impaired osmoregulation, particularly in fresh water, through their toxic effects on the gill tissue. Toxicity was evidenced by epithelial lifting, a decrease in the proportion of secondary lamellae available for gas exchange, and upregulation of superoxide dismutase and heat shock protein genes. Furthermore, exposure to PS-MPs directly affected gill epithelial permeability by maintaining relatively high paracellular permeability through the downregulation of claudin 3 and by modifying the expression of the transcellular transporter Na + /K + -ATPase and cystic fibrosis transmembrane conductance regulator in the gill epithelium. Overall, these findings confirm the toxic effects of PS-MPs on gill tissue and demonstrate, for the first time, that environmentally relevant concentrations of MPs adversely affect gill epithelium permeability during decreased salinity acclimation in the euryhaline fish A. fasciatus., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Becker muscular dystrophy (BMD) is an X-linked disorder due to in-frame mutations in the DMD gene, leading to a less abundant and truncated dystrophin. BMD is less common and severe than Duchenne muscular dystrophy (DMD) as well as less investigated. To accelerate the search for innovative treatments, we developed a rat model of BMD by deleting the exons 45-47 of the Dmd gene. Here, we report a functional and histopathological evaluation of these rats during their first year of life, compared to DMD and control littermates. BMD rats exhibit moderate damage to locomotor and diaphragmatic muscles but suffer from a progressive cardiomyopathy. Single nuclei RNA-seq analysis of cardiac samples revealed shared transcriptomic abnormalities in BMD and DMD rats and highlighted an altered end-addressing of TMEM65 and Connexin-43 at the intercalated disc, along with electrocardiographic abnormalities. Our study documents the natural history of a translational preclinical model of BMD and reports a cellular mechanism for the cardiac dysfunction in BMD and DMD offering opportunities to further investigate the organization role of dystrophin in intercellular communication., (© 2024.

Aim: To evaluate acute toxicity at 6 months after stereotactic body radiotherapy (SBRT) in patients with oligometastatic cancer within the OligoCare cohort., Material and Methods: OligoCare is a prospective, registry-based, single-arm, observational study that aims to report prospective real-world data of patients with oligometastases from solid cancer treated with SBRT (NCT03818503). Primary tumor included non-small cell lung cancer (NSCLC), breast cancer (BC), colorectal cancer (CRC), and prostate cancer (PC). This analysis addresses a secondary endpoint of the trial, acute toxicity within 6 months after SBRT., Results: Out of 1,597registered patients, 1'468 patients were evaluated for acute toxicity. Globally, 290 (20 %) had NSCLC primary disease, 227 (16 %) had BC, 293 (20 %) had CRC, and 658 (45 %) had PC. Concomitant systemic treatment was administered in 527 (35.9 %) patients. According to the EORTC/ESTRO oligometastatic disease (OMD) classification, 828 (56 %) patients had de novo OMD, 464 (32 %) repeat OMD, and 176 (12 %) induced OMD. Acute grade ≥ 3 SBRT related adverse events were reported in 8 (0.5 %) patients, including 2 (0.1 %) fatal AEs. In particular, 6 (0.4 %) grade 3 events were: 1 empyema, 1 pneumonia, 1 radiation pneumonitis, 1 radiation skin injury, 1 decreased appetite, and 1 bone pain. Among those 2 occurred in NSCLC patients, 2 in BC patients, and 1 in CRC and PC patients each. The two (0.1 %) grade 5 toxicity were represented by: pneumonitis and cerebral hemorrhage., Conclusion: OligoCare is the largest prospective registry cohort on oligometastatic disease. Acute toxicity within 6 months was low, confirming the safety of SBRT in the treatment of oligometastases., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Primary hyperparathyroidism (PHPT), an endocrine disorder most commonly caused by parathyroid adenoma (PTA), manifests with a diverse array of symptoms, reflecting the multisystem impact of parathyroid hormone: nephrolithiasis, peptic ulcer disease, psychiatric disorders, muscle weakness, constipation, polyuria, pancreatitis, myalgia, and arthralgia. Rarely do these PTA attain a significant size. PHPT is usually diagnosed through biochemical tests, and radiological imaging characterizes the adenoma. Serum 25-hydroxyvitamin D levels are useful in explaining the large adenoma size. Here, we report a rare case of a 60-year-old female from Morocco who presented with marked dyspnea due to a giant PTA., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Objective: Renal colic (RC) is a common urologic emergency often leading to significant pain and recurrent hospital visits. This study aimed to compare the efficacy and safety of piroxicam versus paracetamol in preventing pain recurrence and hospital readmission in patients treated for RC and discharged from the emergency department (ED)., Methods: A prospective, randomized, single-blind trial was conducted in four EDs. Eligible adults with RC were randomized to receive oral piroxicam, paracetamol, or placebo for 5 days post-ED discharge. Primary outcomes included pain recurrence and ED readmission within 7 days. Secondary outcomes included time to recurrence and treatment-related side effects., Results: Of 1383 enrolled patients, no significant differences were observed among the groups regarding baseline characteristics. Pain recurrence rates within 7 days were 29% (95% confidence interval [CI] 24.9%-33.2%) for piroxicam, 30.3% (95% CI 26.1%-34.5%) for paracetamol, and 30.8% (95% CI 26.6%-35.0%) for placebo, with no significant between-group differences (p = 0.84). Among patients experiencing recurrence, the majority encounter it within the initial 2 days following their discharge (86% in the piroxicam group, 84.1% in the paracetamol group, and 86% in the placebo group, respectively). ED readmission rates were similar across groups: 20.8% (95% CI 17.1%-24.5%) in the piroxicam group, 23.8% (95% CI 19.9%-27.7%) in the paracetamol group, and 22.9% (95% CI 19.1%-26.8%) in the placebo group (p = 0.52). The piroxicam group reported significantly higher adverse effects compared to others., Conclusions: Piroxicam and paracetamol did not demonstrate efficacy in preventing pain recurrence or ED readmission within the first week following RC treatment., (© 2024 The Author(s).

Thyroid hormones play a crucial role in numerous physiological processes, including reproduction. Bisphenol S (BPS) is a structural analog of Bisphenol A known for its toxic effects. Interference of this substitute with normal thyroid function has been described. To investigate the effect of thyroid disruption on ovarian development following maternal exposure to BPS, female rats were exposed, daily, to either AT 1-850 (a thyroid hormone receptor antagonist) (10 nmol/rat) or BPS (0.2 mg/kg) during gestation and lactation. The effects on reproductive outcome, offspring development, histological structures, hormone levels, oxidative status, cytoskeleton proteins expression, and oocyte development gene expression were examined. Our results are in favor of offspring ovarian development disruption due to thyroid disturbance in adult pregnant females. During both fetal and postnatal stages, BPS considerably altered the histological structure of the thyroid tissue as well as oocyte and follicular development, which led to premature ovarian failure and stimulation of oocyte atresia, being accompanied with oxidative stress, hypothalamic-pituitary-ovarian axis disorders, and cytoskeletal dynamic disturbance. Crucially, our study underscores that BPS may induce reproductive toxicity by blocking nuclear thyroid hormone receptors, evidenced by the parallelism and the perfect meshing between the data obtained following exposure to AT 1-850 and those after the treatment by this substitute., (© 2024.

MRKH syndrome, or Mayer-Rokitansky-Küster-Hauser syndrome, a rare congenital disease, manifests as a complete or partial aplasia of the uterus and the vagina's upper two-thirds with normal external genitalia and functioning ovaries. Mayer-Rokitansky-Küster-Hauser syndrome can occur in isolation (type I) or in conjunction with other congenital extragenital deformities affecting the kidneys, skeleton, heart, eyes, or auditory system (type II). The diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome typically relies on imaging studies, with transabdominal ultrasonography serving as the primary modality. However, magnetic resonance imaging is considered the gold standard for detailed assessment of internal genital anatomy. We present the case of an 18-year-old woman without any notable medical history who exhibited primary amenorrhea. Mayer-Rokitansky-Küster-Hauser syndrome type II was suspected on pelvic ultrasound and subsequently confirmed via magnetic resonance imaging. The patient was provided with psychological assistance and planned for vaginoplasty., (© The Author(s) 2024.)

Introduction: chronic haemodialysis patients are a vulnerable population significantly affected by the COVID-19 pandemic, which has had a severe impact on people with co-morbidities and immune system depression, which increases the risk of infection and of developing severe form of COVID-19. The purpose of this study is to assess the impact of the COVID-19 pandemic on the mental health and quality of life of chronic haemodialysis patients., Methods: we conducted a descriptive cross-sectional survey among 175 chronic hemodialysis patients using the Mini International Neuropsychiatric Interview Moroccan Arab Version 5.0.0 scale, the Perceived Stress Scale, and the Quality of Life Scale for Chronic Hemodialysis Patients (KDQOL-SFTM 1.3)., Results: one hundred and seventy-five (175) participants were recruited, of whom 76 patients had COVID-19. COVID-19 infection was significantly associated with age (p=0.018), psychiatric disorders (p=0.00), a history of suicide attempts (p=0.006) and high-stress levels (p=0.01). The quality of life of chronic haemodialysis patients was significantly impaired in patients with COVID-19 (p=0.00), especially in subjects who were elderly (p=0.034), lived alone (p=0.004), had a history of organic (p=0.04), psychiatric (p=0.00), or substance abuse issues (p=0.003), as well as in patients with a symptomatic form (p=0.001), complications (p=0.00), or hospitalisation secondary to COVID-19 (p=0.00), and those with severe stress (p=0.00)., Conclusion: the mental health and quality of life of chronic haemodialysis patients were mainly negatively influenced during the COVID-19 pandemic., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Kaouthar El Mir et al.)

Serotonin syndrome is an iatrogenic disorder induced by serotonergic drug. It is characterised by a symptomatic polymorphism that may create confusion with other clinical conditions, delaying diagnosis and putting the vital prognosis at risk. In light of a case report and a literature review, we here report the clinical case of a patient presenting with confusion, psychomotor agitation, hyperreflexia and spontaneous myoclonus following simultaneous use of paroxetine and amitriptyline. The diagnosis of serotonin syndrome was made after ruling out other possible diagnoses. The patient was admitted to the intensive care unit. This clinical case highlights the importance of thoroughly understanding the clinical manifestations of serotonin syndrome to ensure early and appropriate therapeutic management., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Kaouthar El Mir et al.)

Daphniphyllum macropodum produces alkaloids that are structurally complex with polycyclic, stereochemically rich carbon skeletons. Understanding how these compounds are formed by the plant may enable exploration of their biological function and bioactivities. We employed multiple metabolomics techniques, including a workflow to annotate compounds in the absence of standards, to compare alkaloid content across plants and tissues. Different alkaloid structural types were found to have distinct distributions between genotypes, between tissues and within tissues. Alkaloid structural types also showed different isotope labelling enrichments that matched their biosynthetic relationships. The work suggests that mevalonate derived 30-carbon alkaloids are formed in the phloem region before their conversion to 22-carbon alkaloids which accumulate in the epidermis. This sets the stage for further investigation into the biosynthetic pathway., (© 2024 The Authors. New Phytologist © 2024 New Phytologist Foundation.)

Cisplatin is a cancer therapy drug commonly used. It is well-known for its antineoplastic properties, as well as for its numerous adverse effects, particularly its neurotoxicity. Symptoms associated with a central nervous system injury are unusual but can present a diagnostic challenge. Here, we report a case of a 62-year-old patient who was diagnosed with undifferentiated nasopharyngeal carcinoma. Cisplatin-based chemotherapy was administrated. Five days following the second cycle of treatment, the patient presented neurological disorders. A full biological workup and brain imaging were requested and revealed no abnormalities. The diagnosis of cisplatin encephalopathy was then suspected. Twenty days after cessation of cisplatin therapy, the neurological symptoms began to improve. Based on our case and a review of the literature, cisplatin-induced encephalopathy remains unusual. Its diagnosis is based on a combination of clinical, biological, and radiological criteria and requires the exclusion of other etiologies for neurological disorders in a patient being treated for cancer. Treatment is symptomatic and depends on stopping cisplatin therapy. These neurological adverse effects are often transitory and disappear without major repercussions., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background and Introduction: Optimal dose and fractionation in stereotactic body radiotherapy (SBRT) for oligometastatic cancer patients remain unknown. In this interim analysis of OligoCare, we analyzed factors associated with SBRT dose and fractionation., Materials and Methods: Analysis was based on the first 1,099 registered patients. SBRT doses were converted to biological effective doses (BED) using α/β of 10 Gy for all primaries, and cancer-specific α/β of 10 Gy for non-small cell lung and colorectal cancer (NSCLC, CRC), 2.5 Gy for breast cancer (BC), or 1.5 Gy for prostate cancer (PC)., Results: Of the interim analysis population of 1,099 patients, 999 (99.5 %) fulfilled inclusion criteria and received metastasis-directed SBRT for NSCLC (n = 195; 19.5 %), BC (n = 163; 16.3 %), CRC (n = 184; 18.4 %), or PC (n = 457; 47.5 %). Two thirds of patients were treated for single metastasis. Median number of fractions was 5 (IQR, 3-5) and median dose per fraction was 9.7 (IQR, 7.7-12.4) Gy. The most frequently treated sites were non-vertebral bone (22.8 %), lung (21.0 %), and distant lymph node metastases (19.0 %). On multivariate analysis, the dose varied significantly for primary cancer type (BC: 237.3 Gy BED, PC 300.6 Gy BED, and CRC 84.3 Gy BED), and metastatic sites, with higher doses for lung and liver lesions., Conclusion: This real-world analysis suggests that SBRT doses are adjusted to the primary cancers and oligometastasis location. Future analysis will address safety and efficacy of this site- and disease-adapted SBRT fractionation approach (NCT03818503)., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: BAJF received grants from Accuray, AIRC, IBA and Fondazione IEO-CCM, lecture payments/honoraria from Bayer, Accuray, Astellas, IBA, IPSEN, Astra Zeneca, Tecnologie Avanzate, Recordati, and Novartis, and has board appointments at Astra Zeneca, Bayer, and Seagen.

Background: Striae are fine lines on the body that occur following rapid skin stretching (i.e., following pregnancy, puberty, weight change). The aim of this systematic review was to assess the current literature on treatment outcomes associated with striae., Objective: (1) To assess the efficacy and safety of different treatment options reported for striae and (2) to determine the most efficient treatment options for each subtype of striae., Methods: A systematic search was performed on MEDLINE, Embase, and PubMed with no publication date or language restrictions. All articles with original data and treatment outcomes were included., Results: One hundred fifty-one studies on the treatment of striae met inclusion criteria (83% female, mean age at diagnosis = 30.2), and 4,806 treatment outcomes of striae were described. Energy-based devices were the most reported modality (56%; n = 2,699/4,806), followed by topicals (19%; n = 919/4,806) and combinations (12%; n = 567/4,806). The highest rates of complete response were injection-based devices for striae distensae (7%; n = 12/172), CO 2 lasers for striae alba (4%; n = 12/341), and platelet-rich plasma injections for striae rubra (31%; n = 4/13)., Conclusion: Treatment options for striae are varied, likely indicating a lack of effective treatments due to the diversity in striae subtypes. Improved outcomes in striae management may be achieved with additional research on factors that predict treatment response., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Background: The optimal amount and timing of protein intake in critically ill patients are unknown. REPLENISH (Replacing Protein via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial evaluates whether supplemental enteral protein added to standard enteral nutrition to achieve a high amount of enteral protein given from ICU day five until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve a moderate amount of enteral protein would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients., Methods: In this multicenter randomized trial, critically ill patients will be randomized to receive supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition to achieve a high amount of enteral protein (range of 2-2.4 g/kg/day) or no supplemental enteral protein to achieve a moderate amount of enteral protein (0.8-1.2 g/kg/day). The primary outcome is 90-day all-cause mortality; other outcomes include functional and health-related quality-of-life assessments at 90 days. The study sample size of 2502 patients will have 80% power to detect a 5% absolute risk reduction in 90-day mortality from 30 to 25%. Consistent with international guidelines, this statistical analysis plan specifies the methods for evaluating primary and secondary outcomes and subgroups. Applying this statistical analysis plan to the REPLENISH trial will facilitate unbiased analyses of clinical data., Conclusion: Ethics approval was obtained from the institutional review board, Ministry of National Guard Health Affairs, Riyadh, Saudi Arabia (RC19/414/R). Approvals were also obtained from the institutional review boards of each participating institution. Our findings will be disseminated in an international peer-reviewed journal and presented at relevant conferences and meetings., Trial Registration: ClinicalTrials.gov, NCT04475666 .

Objectives: To evaluate effects of dose intensified salvage radiotherapy (sRT) on erectile function in biochemically recurrent prostate cancer (PC) after radical prostatectomy (RP)., Materials and Methods: Eligible patients had evidence of biochemical failure after RP and a PSA at randomization of ≤ 2 ng/ml. Erectile dysfunction (ED) was investigated as secondary endpoint within the multicentre randomized trial (February 2011 to April 2014) in patients receiving either 64 Gy or 70 Gy sRT. ED and quality of life (QoL) were assessed using CTCAE v4.0 and the EORTC QoL questionnaires C30 and PR25 at baseline and up to 5 years after sRT., Results: 344 patients were evaluable. After RP 197 (57.3 %) patients had G0-2 ED while G3 ED was recorded in 147 (42.7 %) patients. Subsequently, sexual activity and functioning was impaired. 5 years after sRT, 101 (29.4 %) patients noted G0-2 ED. During follow-up, 44.2 % of patients with baseline G3 ED showed any improvement and 61.4 % of patients with baseline G0-2 ED showed worsening. Shorter time interval between RP and start of sRT (p = 0.007) and older age at randomization (p = 0.005) were significant predictors to more baseline ED and low sexual activity in the long-term. Age (p = 0.010) and RT technique (p = 0.031) had a significant impact on occurrence of long-term ED grade 3 and worse sexual functioning. During follow-up, no differences were found in erectile function, sexual activity, and sexual functioning between the 64 Gy and 70 Gy arm., Conclusion: ED after RP is a known long-term side effect with significant impact on patients' QoL. ED was further affected by sRT, but dose intensification of sRT showed no significant impact on erectile function recovery or prevalence of de novo ED after sRT. Age, tumor stage, prostatectomy and RT-techniques, nerve-sparing and observation time were associated with long-term erectile function outcome.ClinicalTrials.gov. Identifier: NCT01272050., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: ED after RP is a common long term side effect with significant impact on patients’ QoL. ED was further affected by sRT, but dose intensification of sRT showed no significant impact on erectile function recovery or prevalence of de novo ED after sRT. Age, prostatectomy technique, nerve-sparing technique, tumour classification, RT technique, and time were factors associated with long term erectile function outcome. Treating physicians need to be aware of the sexual sequelae and offer sexual treatment decision counselling., (© 2024 The Author(s).)

The thioredoxins (Trxs) are ubiquitous and they play a crucial role in various biological processes like growth and stress response. Although the functions of Trxs proteins are described in several previous reports, the function of the isoform Trxh2 of durum wheat (Triticum durum L.), designated as TdTrxh2, in abiotic stress response still unknown. Thus, we aimed in this study the functional characterization of TdTrxh2 through its expression in yeast cells and Arabidopsis plants. Sequence analysis revealed that TdTrxh2 protein shared the conserved redox site with the other Trxh from other plant species. Under various abiotic stresses, TdTrxh2 was up-regulated in leaves and roots of durum wheat. Interestingly, we demonstrated that TdTrxh2 exhibit protective effect on LDH activity against various treatments. Besides, the expression of TdTrxh2 in yeast cells conferred their tolerance to multiple stresses. Moreover, transgenic Arabidopsis expressing TdTrxh2 showed tolerance phenotype to several abiotic stresses. This tolerance was illustrated by high rate of proline accumulation, root proliferation, low accumulation of reactive oxygen species like H 2 O 2 and O 2 ·- , and high antioxidant CAT and POD enzymes activities. All these findings suggested that TdTrxh2 promotes abiotic stress tolerance through the redox homoeostasis regulation and its protective role., (© 2023.

Introduction: Brucellosis in marine mammals (cetacean and pinnipeds) has emerged in a very significant way during the last two decades. Currently Brucella ceti and Brucella pinnipedialis are the two recognized species in marine mammals, but available information is still limited. Several genotypes have been identified, and studies on the relationship between sequence type (ST) and organ pathogenicity or tropism have indicated differences in pathogenesis between B. ceti sequences in cetaceans. The zoonotic potential of this disease is based on the identification of the main sources of introduction and spread of Brucella spp. in the marine environment as well as on the factors of exposure of marine mammals and humans to the bacteria., Bibliographic Review: This article is a bibliographical review on marine mammal brucellosis, including the features, sources and transmission modes of each Brucella species, as well as their potential pathogenicity in animals and humans., Conclusion: Different genotypes of marine Brucella spp have been isolated from marine mammal species but without any evidence of pathology induced by these bacteria. Associated lesions are variable and include subcutaneous abscesses, meningo-encephalomyelitis, pneumonia, myocarditis, osteoarthritis, orchitis, endometritis, placentitis and abortion. The isolation of marine B. spp from marine mammal respiratory parasites associated to lung injury has raised the intriguing possibility that they may serve as a vector for the transmission of this bacterium.The severity of marine B. spp remains unknown due to the lack of an estimate of the prevalence of this disease in marine mammals. The number of suspected human cases is still very limited. However, by analogy with other germs of the genus Brucella responsible for abortion in ruminants and for a febrile and painful state in human beings, prevention measures are essential. The significant increase in the number of strandings coupled with a high seroprevalence in certain species of marine mammals must be considered for people in direct or indirect contact with these animals. Ongoing epidemiological monitoring combined with extensive post-mortem examinations (necropsy, bacteriology and sequencing) of all species of stranded marine mammals would deepen knowledge on the zoonotic potential of marine Brucella species., (Copyright © 2024 SFMTSI.)

The recovery of mitochondrial quality control (MQC) may bring innovative solutions for neuroprotection, while imposing a significant challenge given the need of holistic approaches to restore mitochondrial dynamics (fusion/fission) and turnover (mitophagy and biogenesis). In diabetic retinopathy, this is compounded by our lack of understanding of human retinal neurodegeneration, but also how MQC processes interact during disease progression. Here, we show that mitochondria hyperfusion is characteristic of retinal neurodegeneration in human and murine diabetes, blunting the homeostatic turnover of mitochondria and causing metabolic and neuro-inflammatory stress. By mimicking this mitochondrial remodelling in vitro, we ascertain that N6-furfuryladenosine enhances mitochondrial turnover and bioenergetics by relaxing hyperfusion in a controlled fashion. Oral administration of N6-furfuryladenosine enhances mitochondrial turnover in the diabetic mouse retina (Ins2 Akita males), improving clinical correlates and conferring neuroprotection regardless of glycaemic status. Our findings provide translational insights for neuroprotection in the diabetic retina through the holistic recovery of MQC., (© 2024. The Author(s).)

Obesity is driven by an imbalance between caloric intake and energy expenditure, causing excessive storage of triglycerides in adipose tissue at different sites around the body. Increased visceral adipose tissue (VAT) is associated with diabetes, while pericardial adipose tissue (PAT) is associated with cardiac pathology. Adipose tissue can expand either through cellular hypertrophy or hyperplasia, with the former correlating with decreased metabolic health in obesity. The aim of this study was to determine how VAT and PAT remodel in response to obesity, stress, and exercise. Here we have used the male obese Zucker rats, which carries two recessive fa alleles that result in the development of hyperphagia with reduced energy expenditure, resulting in morbid obesity and leptin resistance. At 9 weeks of age, a group of lean (Fa/Fa or Fa/fa) Zucker rats (LZR) and obese (fa/fa) Zucker rats (OZR) were treated with unpredictable chronic mild stress or exercise for 8 weeks. To determine the phenotype for PAT and VAT, tissue cellularity and gene expression were analyzed. Finally, leptin signaling was investigated further using cultured 3T3-derived adipocytes. Tissue cellularity was determined following hematoxylin and eosin (H&E) staining, while qPCR was used to examine gene expression. PAT adipocytes were significantly smaller than those from VAT and had a more beige-like appearance in both LZR and OZR. In the OZR group, VAT adipocyte cell size increased significantly compared with LZR, while PAT showed no difference. Exercise and stress resulted in a significant reduction in VAT cellularity in OZR, while PAT showed no change. This suggests that PAT cellularity does not remodel significantly compared with VAT. These data indicate that the extracellular matrix of PAT is able to remodel more readily than in VAT. In the LZR group, exercise increased insulin receptor substrate 1 (IRS1) in PAT but was decreased in the OZR group. In VAT, exercise decreased IRS1 in LZR, while increasing it in OZR. This suggests that in obesity, VAT is more responsive to exercise and subsequently becomes less insulin resistant compared with PAT. Stress increased PPAR-γ expression in the VAT but decreased it in the PAT in the OZR group. This suggests that in obesity, stress increases adipogenesis more significantly in the VAT compared with PAT. To understand the role of leptin signaling in adipose tissue remodeling mechanistically, JAK2 autophosphorylation was inhibited using 5 μM 1,2,3,4,5,6-hexabromocyclohexane (Hex) in cultured 3T3-derived adipocytes. Palmitate treatment was used to induce cellular hypertrophy. Hex blocked adipocyte hypertrophy in response to palmitate treatment but not the increase in lipid droplet size. These data suggest that leptin signaling is necessary for adipocyte cell remodeling, and its absence induces whitening. Taken together, our data suggest that leptin signaling is necessary for adipocyte remodeling in response to obesity, exercise, and psychosocial stress., (© 2023 The Authors.

Double-chambered left ventricle (DCLV) is a rare congenital cardiac lesion. It is usually an incidental finding in children and young adults. Diagnosis during fetal life is exceedingly rare. We report a case of DCLV diagnosed in the prenatal period associated with a ventricular septal defect (VSD). Transthoracic echocardiographic and magnetic resonance imaging confirmed the prenatal findings. At seven-month follow-up, the baby was asymptomatic. Transthoracic echocardiographic check-up revealed spontaneous closure of the VSD and stable aspect of the main left ventricle and the accessory chamber., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Vitiligo is a multifactorial dermatosis with many etiological hypotheses that have been suggested for its occurrence. To our knowledge, few epidemiological studies are available on vitiligo induction factors and particularly on the role of exposure to chemicals in the onset of the disease has been found. Therefore, there is need to investigate the relationship between vitiligo and chemical exposures in order to understand this mysterious disease. We conducted a case-control study of patients with vitiligo whose diagnosis was made by a specialist in dermatology. The total study period was of 6 months extending from 1 July to 31 December 2019. The minimum sample size was determined as 46 cases and 92 controls. The control group was gender, age, and professional status matched to the vitiligo group. In the binary logistic regression model, household chemicals/colored toothpaste use, a history of a repeated antibiotic use, and an occupational exposure to phenol/catechol derivatives were significantly associated with vitiligo (three to fourfold increase). Our results suggest that chemical factors play a key role in the occurrence of vitiligo. Therefore, prevention of this dermatosis requires the identification of exposure to the incriminated chemicals in any patient followed for vitiligo. The earlier the diagnosis of 'chemical' or chemically aggravated vitiligo, the better the prognosis for this disease.

Background: Duchenne muscular dystrophy (DMD) is a progressive muscle degenerative disorder, culminating in a complete loss of ambulation, hypertrophic cardiomyopathy and a fatal cardiorespiratory failure. Necroptosis is the form of necrosis that is dependent upon the receptor-interacting protein kinase (RIPK) 3; it is involved in several inflammatory and neurodegenerative conditions. We previously identified RIPK3 as a key player in the acute myonecrosis affecting the hindlimb muscles of the mdx dystrophic mouse model. Whether necroptosis also mediates respiratory and heart disorders in DMD is currently unknown., Methods: Evidence of activation of the necroptotic axis was examined in dystrophic tissues from Golden retriever muscular dystrophy (GRMD) dogs and R-DMDdel52 rats. A functional assessment of the involvement of necroptosis in dystrophic animals was performed on mdx mice that were genetically depleted for RIPK3. Dystrophic mice aged from 12 to 18 months were analysed by histology and molecular biology to compare the phenotype of muscles from mdxRipk3 +/+ and mdxRipk3 -/- mice. Heart function was also examined by echocardiography in 40-week-old mice., Results: RIPK3 expression in sartorius and biceps femoris muscles from GRMD dogs positively correlated to myonecrosis levels (r = 0.81; P = 0.0076). RIPK3 was also found elevated in the diaphragm (P ≤ 0.05). In the slow-progressing heart phenotype of GRMD dogs, the phosphorylated form of RIPK1 at the Serine 161 site was dramatically increased in cardiomyocytes. A similar p-RIPK1 upregulation characterized the cardiomyocytes of the severe DMDdel52 rat model, associated with a marked overexpression of Ripk1 (P = 0.007) and Ripk3 (P = 0.008), indicating primed activation of the necroptotic pathway in the dystrophic heart. MdxRipk3 -/- mice displayed decreased compensatory hypertrophy of the heart (P = 0.014), and echocardiography showed a 19% increase in the relative wall thickness (P < 0.05) and 29% reduction in the left ventricle mass (P = 0.0144). Besides, mdxRipk3 -/- mice presented no evidence of a regenerative default or sarcopenia in skeletal muscles, moreover around 50% less affected by fibrosis (P < 0.05)., Conclusions: Our data highlight molecular and histological evidence that the necroptotic pathway is activated in degenerative tissues from dystrophic animal models, including the diaphragm and the heart. We also provide the genetic proof of concept that selective inhibition of necroptosis in dystrophic condition improves both histological features of muscles and cardiac function, suggesting that prevention of necroptosis is susceptible to providing multiorgan beneficial effects for DMD., (© 2023 The Authors.

Pesticides are increasingly used in combinations in crop protection, resulting in enhanced toxicities for various organisms. Although protein adductomics is challenging, it remains a powerful bioanalytical tool to check environmental exposure and characterize xenobiotic adducts as putative toxicity biomarkers with high accuracy, facilitated by recent advances in proteomic methodologies and a mass spectrometry high-throughput technique. The present study aims to predict the potential neurotoxicity effect of imidacloprid and λ-cyhalothrin insecticides on human neural cells. Our protocol consisted first of 3D in vitro developing neurospheroids derived from human brain tumors and then treatment by pesticide mixture. Furthermore, we adopted a bottom-up proteomic-based approach using nanoflow ultraperformance liquid chromatography coupled with a high-resolution mass spectrometer for protein-adduct analysis with prediction of altered sites. Two proteins were selected, namely, calcium-calmodulin-dependent protein kinase-II (CaMK2) and annexin-A1 (ANXA1), as key targets endowed with primordial roles. De novo sequencing revealed several adduct formations in the active site of 82-ANXA1 and 228-CaMK2 as a result of neurotoxicity, predicted by the added mass shifts for the structure of electrophilic precursors. To the best of our knowledge, our study is the first to adopt a proteomic-based approach to investigate in depth pesticide molecular interactions and their potential to adduct proteins which play a crucial role in the neurotoxicity mechanism.

Introduction: Inferior vena cava (IVC) diameter variability with respiration measured by ultrasound was found to be useful for the diagnosis of heart failure (HF) in ED patients with acute dyspnea. Its value in identifying HF in acute exacerbation of chronic obstructive pulmonary disease exacerbation (AECOPD) was not specifically demonstrated., Objective: To determine the value of ΔIVC in the diagnosis of HF patients with AECOPD., Methods: This is a prospective study conducted in the ED of three Tunisian university hospitals including patients with AECOPD. During this period, 401 patients met the inclusion criteria. The final diagnosis of HF is based on the opinion of two emergency experts after consulting the data from clinical examination, cardiac echocardiography, and BNP level. The ΔIVC was calculated by two experienced emergency physicians who were blinded from the patient's clinical and laboratory data. A cut off of 15% was used to define the presence (< 15%) or absence of HF (≥ 15%). Left ventricular ejection fraction (LVEF) was also measured. The area under the ROC curve, sensitivity, specificity, and positive and negative predictive values were calculated to determine the diagnostic and predictive accuracy of the ΔIVC in predicting HF., Results: The study population included 401 patients with AECOPD, mean age 67.2 years with male (68.9%) predominance. HF was diagnosed in 165 (41.1%) patients (HF group) and in 236 patients (58.9%) HF was excluded (non HF group). The assessment of the performance of the ΔIVC in the diagnosis of HF showed a sensitivity of 37.4% and a specificity of 89.7% using the threshold of 15%. The positive predictive value was 70.9% and the negative predictive value was 66.7%. The area under the ROC curve was 0.71(95%, CI 0.65-0.76). ΔIVC values were not different between HF patients with reduced LVEF and those with preserved LVEF., Conclusion: Our results showed that ΔIVC has a good value for ruling out HF in ED patients consulting for AECOPD., (© 2023.

Background: Emergency medicine is particularly well suited to simulation training. However, evidence for the efficacy of simulation-based medical training remains limited especially to manage high-risk cases such as acute asthma., Objective: The objective of our study was to compare the performance of high-fidelity simulation (HFS) and interactive video-case challenge-based training (IVC) for final-year medical students in the management of acute asthma., Methods: This was a prospective randomized controlled study conducted at the emergency department (ED) of Monastir University hospital ( Tunisia). 69 final-year medical students were randomized to HFS (n = 34) and IVC (n = 35) training on acute asthma topic. The study was conducted over a 1-week period. Efficacy of each teaching method was compared through the use of multiple-choice questionnaires (MCQ) before (pre-test), after (post-test) training and a simulation scenario test conducted 1 week later. The scenario was based on acute asthma management graded on predefined critical actions using two scores: the checklist clinical score (range 0 to 30), and the team skills score (range 0 to 16). Student satisfaction was also evaluated with the Likert 5 points scale. Two years after the post-test, both groups underwent a third MCQ testing to assess sustainability of knowledge., Results: There were no differences in age between groups. There was no statistically significant difference between the HFS and IVC groups pre-test scores (p = 0.07). Both groups demonstrated improvement in MCQ post-test from baseline after training session; the HFS MCQ post-test score increased significantly more than the IVC score (p < 0.001). The HFS group performed better than the IVC group on the acute asthma simulation scenario (p < 0.001). Mean checklist clinical score and mean team skills score were significantly higher in HFS group compared to IVC group (respectively 22.9 ± 4.8 and 11.5 ± 2.5 in HFS group vs 19.1 ± 3 and 8.4 ± 3.1 in IVC group) (p < 0.001). After 2 years, MCQ post-test scores decreased in both groups but the decrease was lower in HFS group compared to the IVC group., Conclusion: High-fidelity simulation-based training was superior to interactive video-case challenge for teaching final year medical students,and led to more long-term knowledge retention in the management of simulated acute asthma patients., Trial Registration: The study was registered at www., Clinicaltrials: gov NCT02776358 on 18/05/2016., (© 2023.

We present a genome assembly from an individual female Endotricha flammealis (the Rose-flounced Tabby; Arthropoda; Insecta; Lepidoptera; Pyralidae). The genome sequence is 473.9 megabases in span. Most of the assembly is scaffolded into 32 chromosomal pseudomolecules, including the W and Z sex chromosomes. The mitochondrial genome has also been assembled and is 15.23 kilobases in length. Gene annotation of this assembly on Ensembl identified 17,578 protein coding genes., Competing Interests: No competing interests were disclosed., (Copyright: © 2023 Boyes D et al.)

High-grade gliomas represent the most common group of infiltrative primary brain tumors in adults associated with high invasiveness, agressivity, and resistance to therapy, which highlights the need to develop potent drugs with novel mechanisms of action. The aim of this study is to reveal changes in proteome profiles under stressful conditions to identify prognostic biomarkers and altered apoptogenic pathways involved in the anticancer action of human isocitrate dehydrogenase (IDH) mutant high-grade gliomas. Our protocol consists first of a 3D in vitro developing neurospheroid model and then treatment by a pesticide mixture at relevant concentrations. Furthermore, we adopted an untargeted proteomic-based approach with high-resolution mass spectrometry for a comparative analysis of the differentially expressed proteins between treated and nontreated spheroids. Our analysis revealed that the majority of altered proteins were key members in glioma pathogenesis, implicated in the cellular metabolism, biological regulation, binding, and catalytic and structural activity and linked to many cascading regulatory pathways. Our finding revealed that grade-IV astrocytomas promote the downstream of the mitogen-activated-protein-kinases/extracellular-signal-regulated kinase (MAPK1/ERK2) pathway involving massive calcium influx. The gonadotrophin-releasing-hormone signaling enhances MAKP activity and may serve as a negative feedback compensating regulator. Thus, our study can pave the way for effective new therapeutic and diagnostic strategies to improve the overall survival.

Duchenne muscular dystrophy (DMD) is a devastating X-linked muscular disease, caused by mutations in the DMD gene encoding Dystrophin and affecting 1:5000 boys worldwide. Lack of Dystrophin leads to progressive muscle wasting and degeneration resulting in cardiorespiratory failure. Despite the absence of a definitive cure, innovative therapeutic avenues are emerging. Myopathologic studies are important to further understand the biological mechanisms of the disease and to identify histopathologic benchmarks for clinical evaluations. We conducted a myopathologic analysis on twenty-four muscle biopsies from DMD patients, with particular emphasis on regeneration, fibro-adipogenic progenitors and muscle stem cells behavior. We describe an increase in content of fibro-adipogenic progenitors, central orchestrators of fibrotic progression and lipid deposition, concurrently with a decline in muscle regenerative capacity. This regenerative impairment strongly correlates with compromised activation and expansion of muscle stem cells. Furthermore, our study uncovers an early acquisition of a senescence phenotype by DMD-afflicted muscle stem cells. Here we describe the myopathologic trajectory intrinsic to DMD and establish muscle stem cell senescence as a pivotal readout for future therapeutic interventions., (© 2023.

Bacterial resistance to different antimicrobial agents is growing with alarming speed, especially when bacterial cells are living in biofilm. Hybrid nanoparticles, synthesized through the green method, hold promise as a potential solution to this challenge. In this study, 66 actinomycete strains were isolated from three distinct marine sources: marine sediment, the algae Codium bursa , and the marine sponge Chondrosia reniformis . From the entirety of the isolated strains, one strain, S26, identified as Saccharopolyspora erythrea , was selected based on its taxonomic position and significant antimicrobial activity. Using the biomass of the selected marine Actinobacteria , the green synthesis of eco-friendly silver carbonate nanoparticles (BioAg 2 CO 3 NPs) is reported for the first time in this pioneering study. The BioAg 2 CO 3 NPs were characterized using different spectroscopic and microscopic analyses; the synthesized BioAg 2 CO 3 NPs primarily exhibit a triangular shape, with an approximate size of 100 nm. Biological activity evaluation indicated that the BioAg 2 CO 3 NPs exhibited good antimicrobial activity against all tested microorganisms and were able to remove 58% of the biofilm formed by the Klebsiella pneumoniae kp6 strain.

Objective: To determine the impact of mobile-phone telemonitoring on patients' adherence and satisfaction with posttrauma pain treatment., Materials and Methods: We conducted a prospective randomized clinical trial including patients with minor trauma discharged from the emergency department (ED) with analgesic treatment. Patients were randomized to one of 3 groups, the control group, where patients received a phone call on day-7, the short message service (SMS) group, where patients received a daily text message to remind them to take their treatment during 7 days, and the mobile-phone based telemonitoring (TLM) group. Patients' adherence to analgesic treatments using the Morisky Medication Adherence Scale, current pain by using a visual analogue scale, and patients' satisfaction were assessed. For the TLM group, the assessment was performed at day-2, 4 and 7., Results: Good adherence was observed in 418 patients (92.9%) in the TLM group versus 398 patients (88.6%) in the SMS group and 380 patients (84.8%) in the control group ( P <0.001). The factor mostly associated with adherence was telemonitoring (OR 2.40 95% CI 1.55-3.71). The decrease in pain visual analogue scale was highest in the TLM group compared with SMS and control groups ( P <0.001). The percentage of patients' satisfaction at 7 days post-ED discharge was 93% in the TLM group versus 88% in the SMS group and 84% in the standard group ( P =0.02)., Discussion: Our findings suggest that mobile-phone-based telemonitoring is beneficial in the treatment of pain in trauma patients after ED discharge. This approach improved patients' adherence and satisfaction., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Cervical teratomas are extremely rare germ cell tumours and it is much more common in newborn than adults, and in contrast to the paediatric cases adult teratomas have been highly malignant. Cervical teratoma incorporates lesions arising in the anterior and posterior triangles of the neck. This tumor can reach enormous size and cause airway obstruction and patients should be quickly treated. Surgery is the primary modality of treatment as malignant transformation can occur. Hereby, we present a case of benign teratoma of neck in adult which was completely misdiagnosed preoperatively due to its rare occurrence in adults.Even though cervical teratoma of adult is extremely rare, it should be considered as an important differential diagnosis in patient of midline cystic neck swelling. Preoperative radiological investigations requires high index of suspicion. Complete surgical resection is recommended. We believe that upper cervicotomy approach is a safe and effective method for the treatment of mature cervical teratoma with a few protruding into the superior mediastinum., Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-023-03748-8., Competing Interests: Competing InterestNo., (© Association of Otolaryngologists of India 2023.

Pesticides are widely used, resulting in continuing human exposure with potential health impacts. Some exposures related to agricultural works have been associated with neurological disorders. Since the 2000s, the hypothesis of the role of pesticides in the occurrence of central nervous system (CNS) tumors has been better documented in the literature. However, the etiology of childhood brain cancers still remains largely unknown. The major objective of this work was to assess the potential role of pesticide exposure as a risk factor for CNS tumors based on questionnaires and statistical analysis of information collected from patients hospitalized in the Neurosurgery Department of the Habib Bourguiba Hospital Medium in Sfax, Tunisia, during the period from January 1, 2022, to May 31, 2023. It also aimed to develop a simple and rapid analytical method by the gas chromatography-mass spectrometry technique for the research traces of pesticide metabolites in some collected human brain tumor tissues in order to more emphasize our hypothesis for such a correlation between pesticide exposure and brain tumor development. Patients with a history of high-risk exposure were selected to conduct further analysis. Chemometric methods were adapted to discern intrinsic variation between pathological and control groups and ascertain effective separation with the identification of differentially expressed metabolites accountable for such variations. Three samples revealed traces of pesticide metabolites that were mostly detected at an early age. The histopathological diagnosis was medulloblastoma for a 10-year-old child and high-grade gliomas for 27- and 35-year-old adults. The bivariate analyses (odds ratio >1 and P value <5%) confirmed the great probability of developing cancer by an exposure case. The Cox proportional hazards model revealed the risk of carcinogenicity beyond the age of 50 as a long-term effect of pesticide toxicity. Our study supports the correlation between pesticide exposure and the risk of development of human brain tumors, suggesting that preconception pesticide exposure, and possibly exposure during pregnancy, is associated with an increased childhood brain tumor risk. This hypothesis was enhanced in identifying traces of metabolites from the carbamate insecticide class known for their neurotoxicity and others from pyridazinone, organochlorines (OCs), triazole fungicide, and N-nitroso compounds known for their carcinogenicity. The 2D-OXYBLOT analysis confirmed the neurotoxicity effect of insecticides to induce oxidative damage in CNS cells. Aldicarb was implicated in brain carcinogenicity confirmed by the identification of oxime metabolites in a stress degradation study. Revealing "aziridine" metabolites from the OC class may better emphasize the theory of detecting traces of pesticide metabolites at an early age. Overall, our findings lead to the recommendation of limiting the residential use of pesticides and the support of public health policies serving this objective that we need to be vigilant in the postmarketing surveillance of human health impacts., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

Catalases are crucial antioxidant enzymes that regulate plants responses to different biotic and abiotic stresses. It has been previously shown that the activities of durum wheat catalase proteins (TdCAT1) were stimulated in the presence of divalent cations Mn 2+ , Mg 2+ , Fe 2+ , Zn 2+ , and Ca 2+ . In addition, TdCAT1s can interact with calmodulins in calcium-independent manner, and this interaction stimulates its catalytic activity in a calcium-dependent manner. Moreover, this activity is further enhanced by Mn 2+ cations. The current study showed that wheat catalase presents different phosphorylation targets. Besides, we demonstrated that catalase is able to interact with Mitogen Activated Proteins kinases via a conserved domain. This interaction activates wheat catalase independently of its phosphorylation status but is more promoted by Mn 2+ , Fe 2+ and Ca 2+ divalent cations. Interestingly, we have demonstrated that durum wheat catalase activity is differentially regulated by Mitogen Activated Proteins kinases and Calmodulins in the presence of calcium. Moreover, the V0 of the reaction increase gradually following the increasing quantities of Mn 2+ divalent cations. Such results have never been described before and suggest i) complex regulatory mechanisms exerted on wheat catalase, ii) divalent cations (Mn 2+ ; Mg 2+ ; Ca 2+ and Fe 2+ ) act as key cofactors in these regulatory mechanisms., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Background: Protein intake is recommended in critically ill patients to mitigate the negative effects of critical illness-induced catabolism and muscle wasting. However, the optimal dose of enteral protein remains unknown. We hypothesize that supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition formula to achieve high amount of enteral protein (range 2-2.4 g/kg/day) given from ICU day 5 until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve moderate amount enteral protein (0.8-1.2 g/kg/day) would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients., Methods: The REPLENISH (Replacing Protein Via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial is an open-label, multicenter randomized clinical trial. Patients will be randomized to the supplemental protein group or the control group. Patients in both groups will receive the primary enteral formula as per the treating team, which includes a maximum protein 1.2 g/kg/day. The supplemental protein group will receive, in addition, supplemental protein at 1.2 g/kg/day starting the fifth ICU day. The control group will receive the primary formula without supplemental protein. The primary outcome is 90-day all-cause mortality. Other outcomes include functional and quality of life assessments at 90 days. The trial will enroll 2502 patients., Discussion: The study has been initiated in September 2021. Interim analysis is planned at one third and two thirds of the target sample size. The study is expected to be completed by the end of 2025., Trial Registration: ClinicalTrials.gov Identifier: NCT04475666 . Registered on July 17, 2020., (© 2023. The Author(s).)

In recent years, carbon fiber has experienced a significant surge in popularity attributed to its exceptional properties, including its high-temperature resistance, mechanical strength, and cost-effectiveness. Many industries have been attracted to the prevalent use of carbon-fiber-reinforced polymers or plastics (CFRP). However, the increasing demand for carbon fiber has created a waste recycling problem that needs to be addressed. This research aimed to develop a recycled composite using PET waste as a solution to the growing demand for both materials. The recycled carbon fibers were processed chemically and mechanically to generate power for this process. Various samples were tested with different proportions of CF (10%, 20%, 30%, and 40%) to analyze their mechanical properties. The recycled composites are examined under tensile test conditions to further explore the waste carbon reinforcement's effect on polymers' characteristics. Scanning electron microscopy was also utilized for mechanical morphology evaluations. After analyzing the data, it was found that samples containing 20% CF had the highest elastic modulus value among all the mixes. This is attributed to the reinforcing effect of the fibers. The Elasticity Modulus of the filaments increased with the concentration of CF, reaching its peak at 20% before decreasing. This trend is also apparent in the visual representations. When compared to recycling, the Elasticity Modulus value of 20% CF filament increased by 97.5%. The precise value for CF with a 20% filament is 4719.3 MPa. Moreover, the composite samples were analyzed using SEM to characterize them, and it was discovered that the incorporation of 20% CF/PET filler produced the composition with the highest strength.

Microplastics (MPs), plastic particles smaller than 5 mm in diameter, have received extensive attention as new environmental pollutants with still unexplored potential ecological risks. The main objective of the present study is to see if the concomitant exposure to MPs and Cd is more toxic than that to MPs or Cd separately in Aphanius fasciatus. Immature female were exposed to Cd and/or MPs for 21 days, and the subsequent effects were monitored by a combination of biochemical, histological and molecular toxicity markers. Exposure to Cd, but not to MPs, increased metallothioneins content and mRNA levels of the metallothioneins gene MTA both in liver and gills. In addition, we observed a significant oxidative stress response at histological, enzymatic (Catalase and Superoxide dismutase), non-enzymatic (proteins sulfhydryl and malondialdehyde) and gene expression levels to both toxicants in both tissues, particularly in gills, but no clear evidence for interaction between the two factors. Our results indicate a major effect of MPs on gills at different organizational levels. Finally, exposure to both MPs and Cd induced spinal deformities, although bone composition was only altered by the latter, whereas MTA mRNA bone levels were only increased realtive to controls in doubly-exposed samples. Interestingly, the simultaneous use of both pollutants produced the same effects as Cd and MPs alone, probably due to reduced bioavailability of this heavy metal., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.
