RESUMO

The metritis complex (MC), a group of post-partum uterine diseases, is associated with increased treatment costs and reduced milk yield and fertility. The goal of this study was to identify genetic variants, genes, or genomic regions that modulate MC disease. A genome-wide association study was performed using a single-locus mixed linear model of 1967 genotypes (624,460 SNPs) and metritis complex records. Then, in-silico functional analyses were performed to detect biological mechanisms and pathways associated with the development of MC. The ATP8A2, COX16, AMN, and TRAF3 genes, located on chromosomes 12, 10, and 21, were associated with MC at p ≤ 0.0001. These genes are involved in the regulation of cholesterol metabolism in the stromal tissue of the uterus, which can be directly associated with the mode of transmission for pathogens causing the metritis complex. The modulation of cholesterol abundance alters the efficiency of virulence factors and may affect the susceptibility of the host to infection. The SIPA1L1, DEPDC5, and RNF122 genes were also significantly associated with MC at p ≤ 0.0001 and are involved in the PI3k-Akt pathway, responsible for activating the autophagic processes. Thus, the dysregulation of these genes allows for unhindered bacterial invasion, replication, and survival within the endometrium.

RESUMO

The intricate relationship between alcohol consumption and intracerebral hemorrhage (ICH) presents a nuanced field of study, especially concerning the dose-dependent impact on secondary brain injury (SBI). Recognizing the established risks associated with heavy drinking, this review delves deeper into the less understood territories of low to moderate alcohol consumption. By systematically analyzing recent studies, we uncover critical insights into how varying alcohol intake levels modulate ICH risk through mechanisms such as microglial activation, oxidative stress, and the protective potential of polyphenols. This analysis extends beyond the hypertensive effects of heavy alcohol use to explore the complex molecular pathophysiology involved in alcohol-related ICH. Our findings indicate that while heavy alcohol use unequivocally exacerbates ICH risk, moderate consumption and its associated polyphenols may offer neuroprotective effects against SBI, albeit within a finely balanced threshold. This review highlights the significant gaps in current understanding and underscores the urgent need for targeted research to elucidate these complex interactions. Through this comprehensive examination, we aim to inform more nuanced public health policies and intervention strategies, taking into account the diverse effects of alcohol consumption on ICH risk.

RESUMO

BACKGROUND: There is ample evidence supporting the use of different manipulative therapy techniques for Cervicogenic Headache (CgH). However, no technique can be singled as the best available treatment for patients with CgH. Therefore, the objective of the study is to find and compare the clinical effects of cervical spine over thoracic spine manipulation and conventional physiotherapy in patients with CgH. DESIGN, SETTING, AND PARTICIPANTS: It is a prospective, randomized controlled study conducted between July 2020 and January 2023 at the University hospital. N = 96 eligible patients with CgH were selected based on selection criteria and they were divided into cervical spine manipulation (CSM; n = 32), thoracic spine manipulation (TSM; n = 32) and conventional physiotherapy (CPT; n = 32) groups, and received the respective treatment for four weeks. Primary (CgH frequency) and secondary CgH pain intensity, CgH disability, neck pain frequency, neck pain intensity, neck pain threshold, cervical flexion rotation test (CFRT), neck disability index (NDI) and quality of life (QoL) scores were measured. The effects of treatment at various intervals were analyzed using a 3 × 4 linear mixed model analysis (LMM), with treatment group (cervical spine manipulation, thoracic spine manipulation, and conventional physiotherapy) and time intervals (baseline, 4 weeks, 8 weeks, and 6 months), and the statistical significance level was set at P < 0.05. RESULTS: The reports of the CSM, TSM and CPT groups were compared between the groups. Four weeks following treatment CSM group showed more significant changes in primary (CgH frequency) and secondary (CgH pain intensity, CgH disability, neck pain frequency, pain intensity, pain threshold, CFRT, NDI and QoL) than the TSM and CPT groups (p = 0.001). The same gradual improvement was seen in the CSM group when compared to TSM and CPT groups (p = 0.001) in the above variables at 8 weeks and 6 months follow-up. CONCLUSION: The reports of the current randomized clinical study found that CSM resulted in significantly better improvements in pain parameters (intensity, frequency and threshold) functional disability and quality of life in patients with CgH than thoracic spine manipulation and conventional physiotherapy. TRIAL REGISTRATION: Clinical trial registration: CTRI/2020/06/026092 trial was registered prospectively on 24/06/2020.

RESUMO

Background: Femoral neck fractures in children are uncommon, making up little more than 1% of all paediatric fractures. It's not apparent which type of internal fixation-closed or open-is preferable in these situations when it comes to therapeutic options. When treating children with displaced femoral neck fractures, serious problems can arise. Methods: Five databases were examined: Medline Plus, PubMed, Scopus, Science Direct, and Web of Science. The outcomes that were relevant for the meta-analysis were non-union, coxa vara, and avascular necrosis. Using the RevMan file, we extracted the data and carried out the analysis (Review Manager Version 5.3). Results: 294 patients had ORIF procedures and 266 patients had CRIF procedures in the included trials. Regarding the outcome of avascular necrosis, we discovered that there was no statistically significant difference between the two groups (RR = 0.84, [95% confidence range (CI) = 0.60, 1.18], P = 0.32). There was homogeneity in the data (P = 0.22, I2 = 27%). When it came to coxa vara, there was no statistically significant difference between the two groups (RR = 0.69, [95% CI = 0.30, 1.58], P = 0.38). There was homogeneity in the data (P = 0.22, I2 = 27%). Regarding non-union, the similar outcome was seen (RR = 0.45, [95% CI = 0.16, 1.14], P = 0.12). There was homogeneity in the data (P = 0.49, I2 = 0%). Conclusion: Regarding reducing the risk of non-union, coxa vara, and avascular necrosis, we did not find any difference between CRIF and ORIF. To validate this outcome, however, additional research on the various variables (fracture type, age, displacement, fixation technique, and duration of surgery) is required. Sorting patients based on the kind of fracture will ensure that the right approach is used for each type.

RESUMO

INTRODUCTION: Frozen shoulder is a very common musculoskeletal condition and the evidence related to the additional effects of extracorporeal shockwave therapy (ESWT) with intra-articular (IA) lidocaine injection in individuals with frozen shoulder is rare. Therefore, this study aims to compare and investigate the additional effects of extracorporeal shockwave therapy (ESWT) with intra-articular (IA) lidocaine injection in a frozen shoulder. METHODS: Sixty eligible participants with frozen shoulder were included and the active group (n = 30, age 52.12 ± 5.2 years) received a lidocaine injection (1% lidocaine (Xylocaine) and 2cc (80 mg) methylprednisolone acetate) with active ESWT (3.5 bar air pressure and 2000 pulses with an energy flux density (EFD) » 0.16 mJ/mm2) three sessions a week for 4 weeks. The placebo group (n = 30, age 53.56 ± 5.5 years) received lidocaine injection with placebo treatment (a special head that blocked the shock waves) three sessions a week for 4 weeks. Both groups received progressive resistance exercises (PRE) to the shoulder muscles. The primary outcome was pain intensity, measured with the visual analogue scale. The other outcome measures were the thickness of the coracohumeral ligament (CHL) measured by magnetic resonance imaging (MRI), abduction, and lateral rotation range of motion (ROM), functional disability, kinesiophobia, depression status, and quality of life. Participants were assessed at baseline, after 4 weeks, 8 weeks, and at 6-month follow-up. RESULTS: The post-intervention at 4 weeks showed an improvement of 2.0 (CI 95% 1.71-2.28) in the active group compared to the placebo group. Similar effects were noted after 8 weeks (2.2) (CI 95% 1.91-2.48) and at the 6-month (1.9) (CI 95% 1.61-2.18) follow-up. Similar improvements were also found in the thickness of the CHL ligament (0.6) (CI 95% 0.46-0.73), abduction and lateral rotation (ROM) (- 23.6) (CI 95% - 27.47 to -19.72), (- 18.10) (CI 95% - 19.72 to - 16.47), functional disability (16.2) (CI 95% 14.85-17.54), kinesiophobia (11.0 (CI 95% 10.21-11.98), depression status (4.4) (CI 95% 4.03-4.76) and quality of life (0.9) (CI 95% 0.79-1.00) (p = 0.001) at the 6-month follow-up period, where mean estimates and their confidence intervals all included worthwhile effects. There were no adverse reactions or side effects noted in either the active or placebo groups during and after the treatment. CONCLUSIONS: The study concluded that the addition of extracorporeal shockwave therapy after intra-articular lidocaine injection improves pain, functional disability, range of motion, kinesiophobia, depression status, and quality of life in people with frozen shoulder.

RESUMO

Medical education continually adapts to the needs of future health care professionals, with student motivation in research being a pivotal aspect. This study at Alfaisal University aimed to explore the motivations, benefits, and challenges faced by medical students in extracurricular research activities. Using a mixed-method approach, we combined quantitative surveys with qualitative group interviews. Findings revealed that both extrinsic (e.g., enhancing postgraduate training prospects) and intrinsic (e.g., personal interest and skill refinement) factors significantly motivate students to be involved in research activities. Participants unanimously acknowledged skill enhancement, particularly in literature comprehension, creative ideation, and networking. However, challenges such as conflicts with course scheduling, lack of hands-on experiences, and mentorship issues were identified as potential barriers to research participation. Addressing these barriers and understanding motivations can inform the design of research programs, enhancing the overall student research experience. This study underscores the importance of research in medical education, emphasizing the need for institutions to prioritize addressing challenges and leveraging benefits to prepare medical students for a research-integrated clinical future.NEW & NOTEWORTHY This article examines the motivating factors and obstacles of extracurricular research in Alfaisal University, Saudi Arabia. The study utilizes a mixed methodology of online surveys and in-person group interviews to gain insights from the medical students of the university. We revealed several extrinsic and intrinsic motivators that drove the students; however, there remain several challenges to students during their research journey. Addressing these challenges will help the students obtain a more fruitful, educational research experience.

RESUMO

BACKGROUND: The primary aim of this study was to examine the clinical characteristics and outcomes of older patients who underwent hip fracture repair surgery. The secondary aims were to assess the predictors of the choice of spinal or general anaesthesia and to explore the risk factors for all-cause mortality. METHODS: This three-tertiary centres study was conducted at a tertiary care centre in Jordan. Clinical data include previous fracture history; medication details; comorbidities; surgical approach; and postoperative pain management. RESULTS: Overall, 1084 patients who underwent hip fracture repair were included in this study. The mean age of patients was 78 years, and 55.2% were women. Twenty-four were treated with bisphosphonates before the fracture, whereas 30 were in steroid therapy. Overall, 61.8% of patients underwent spinal anaesthesia, whereas 38.2% underwent general anaesthesia. Spinal anaesthesia group had a lower prevalence of cardiovascular accidents (16.3% vs. 22.3%, p = 0.014) and Alzheimer's (3.4% vs. 1.4%, p = 0.049) than the general anaesthesia group. In the spinal anaesthesia group, postoperative opioid administration (p = 0.025) and postoperative blood transfusion (p = 0.011) occurred more frequently than general anaesthesia group. In hospital, 30-day and all-cause mortality were comparable between both groups. Diabetes mellitus (HR = 2.6; 95%CI = 1.5-4.4; p = 0.001); cemented hip hemiarthroplasty (HR = 2.4; 95%CI = 1.1-5.1; p = 0.025); deep venous thrombosis/pulmonary embolism (HR = 5.0; 95%CI = 1.2-12.9; p = 0.001); and readmission within 1 month from surgery (HR = 3.6; 95%CI = 2.0-6.3; p < 0.001) were all significant predictors of mortality. CONCLUSIONS: This study provides insights into the outcomes and factors associated with different anaesthesia types in hip fracture repair surgery. The anaesthesia type does not affect all-cause mortality in patients undergoing hip fracture repair.

RESUMO

Background: Hypospadias is a congenital abnormality of anterior urethral and penile development where the urethral meatus is ectopically located on the ventral aspect of the penis. It is a relatively common condition affecting ~1 in 250 male birth. Extended-Tubularized Incised Plate (E-TIP) is a modification of Snodgrass repair by extending the midline incision to the apical part of the glans resulting in a more normal appearing location of the meatus and straight urinary stream without increasing the risk of complications. Aim of study: To evaluate functional and cosmetic outcomes of E-TIP repair for mid-shaft and distal hypospadias as a modification of Snodgrass repair. Patient and method: A prospective cross-sectional study including 53 cases of mid-to-distal hypospadias repaired with the E-TIP technique between November 2019 and February 2022 in Baghdad. The authors start with the standard technique described by Snodgrass, but the midline incision of the urethral plate extended up to the apical part of the glans tip, and tabularization started distally creating a slit-like a neomeatus. Outcome assessment depended on an objective evaluation of the following parameters: maximum flow rate, post-void residual, Hypospadias Objective Score Evaluation (HOSE) score, and direction of the urinary stream. Results: The mean age was 3.4±2.1 years, ranging from 0.6 to 9 years. The mean duration of follow-up was 14.4±6.9 months, and the location of the meatus was coronal in 16 patients (30%), subcoronal in 25 (47%), and mid-distal shaft in 12 (23%). The glans width was greater than or equal to 14 mm in 46 patients (87%) and less than 14 mm in 7 (13%). Q.max was above the fifth percentile of age-related uroflowmetry nomograms for healthy children 5-15 years old in 29 boys (93.5%) and below the fifth percentile in 2 (6.5%). Post-void residual urine was less than 10% of voided volume in 28 out of 31 boys (90%) and greater than 10% in 3 (10%). Regarding cosmetic outcomes, 50 boys (94%) had good penile appearance and their HOSE score greater than or equal to 14 with a slit-like meatus located at the tip of the glans, while 3 (6%) of them their score was less than 14. The overall mean HOSE score postoperatively for all patients was 15±0.9. Six patients (11%) had a deviated urinary stream and 47 (89%) had a straight stream. Conclusion: E-TIP repair is a good alternative to standard Snodgrass repair for mid-shaft to distal hypospadias with a good functional and cosmetic outcome, particularly the neomeatus position at the tip of the glans, which is similar to the normal one without increasing the risk of meatal stenosis.

RESUMO

Background: The aim was perusal of the treatment strategies, clinical outcomes and factors impacting these outcomes in thymoma. Materials and methods: A total of 119 patients diagnosed and treated cases of thymoma, at our hospital, were taken for analysis. Thirty-one patients were excluded due to inadequate medical records. Descriptive statistics were used to report demographic and clinical characteristics. Time period between diagnosis and death was defined as overall survival (OS). Multivariate analysis (MVA), using cox regression modelling, was done by including clinicopathological factors in a bid to identify prognostic factors influencing OS. SPSS version 26 was used for statistical analysis. Results: The mean age of the patients was 52.17 years and 39 (44.3%), 19 (21.6%), 17 (1.3%) and 13 (4.8%) patients presented with Masaoka stage II, IV, III and I, respectively. Surgery was done in 64 (72.7%) of the patients as a part of the treatment strategy. Radiotherapy was administered to a total of 57 patients with a median dose of 50.4 Gy. Early Masaoka stage at presentation and use of surgery in the treatment plan were statistically significant prognostic factors for a better overall survival on multivariate analysis. Conclusion: Judicious use of radiotherapy and chemotherapy in locally advanced cases may render them resectable. In a bid to gain good survival rates, aggressive multimodality treatment should be offered to the patients.

RESUMO

The importance of developing a robust remote workforce in academic radiology has come to the forefront due to several converging factors. COVID-19, and the abrupt transformation it precipitated in terms of how radiologists worked, has been the biggest impetus for change; concurrent factors such as increasing examination volumes and radiologist burnout have also contributed. How to best advance the most desirable and favorable aspects of remote work while preserving an academic environment that fulfills the tripartite mission is a critical challenge that nearly all academic institutions face today. In this article, we discuss current challenges in academic radiology, including effects of the COVID-19 pandemic, from three perspectives-the radiologist, the learner, and the health system-addressing the following topics: productivity, recruitment, wellness, clinical supervision, mentorship and research, educational engagement, radiologist access, investments in technology, and radiologist value. Throughout, we focus on the opportunities and drawbacks of remote work, to help guide its effective and reliable integration into academic radiology practices.

RESUMO

BACKGROUND: High-Impact Practices (HIPs) are educational practices that have been shown to increase rates of student retention, engagement, and persistence to graduation which help them to become high achievers and lifelong learners. Universities strongly encourage faculty members to incorporate one or more of these HIPs in order to improve active learning among students. Students are met with a variety of experiences that are not entirely of their choice, including expectations for academic performance, interactions with faculty, staff, and peers, and extracurricular activities that may or may not match their expectations and skills. Higher retention and high-grade achievement rates are attributed to HIPs. The mechanism by which HIPs improve retention is poorly understood. AIMS AND OBJECTIVES: There are numerous analyses of the objectives particular to undergraduate medical education in recent years. There have been proposed three major target categories. Undergraduate medical education has been positioned within a liberal education framework, where the main objective is to equip students with the critical thinking abilities, broad general education, and subject-specific knowledge they will need to be able to effectively problem-solve, adapt to new roles, and apply public health thinking and practices to a variety of situations. We tried to incorporate HIPs in a medical curriculum at the Faculty of Medicine, Northern Border University, by giving them topics that can be used to create public awareness about the selected objectives which may help the community greatly. METHODOLOGY: Students were asked to make posters or videos on the topics and were asked to write reflections about their experience and give feedback to the coordinators for improvements and to make these HIPs better so that they can be included uniformly in the other courses as well. RESULTS AND CONCLUSIONS: Based on results from a random sample of undergraduate students, we draw the conclusion that HIPs are correlated with engagement, which is the alignment of the student's critical thinking and ability to work in effective teams, group projects, learning communities, and sequence courses. HIPs have an impact on involvement among students across the world. HIPs are effective to the extent that they engage pupils, encouraging a greater commitment, which is one way to understand their success.

RESUMO

Bone is the second most common site of metastasis in patients with thyroid cancer (TC) and dramatically impacts overall survival and quality of life with no definitive cure, yet there is no extensive study of the demographic and clinical risk factors in the recent literature. Data regarding 120,754 TC patients with bone metastasis were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate analyses were used to identify the risk factors of bone metastasis occurring in various histologies of TC. Cox regression was performed to analyze the influence of bone metastasis on overall survival. Hazard ratios were computed to analyze the association between bone metastasis and the primary outcomes. Of the 120,754 records collected from the SEER database from 2000 to 2019, 976 (0.8%) presented with bone metastasis, with occurrence being the greatest in patients of age ≥ 55 years (OR = 5.63, 95%CI = 4.72-6.71), males (OR = 2.60, 95%CI = 2.27-2.97), Blacks (OR = 2.38, 95%CI = 1.95-2.9) and Asian or Pacific Islanders (OR = 1.90, 95%CI = 1.58-2.27), and single marital status. TC patients presenting with bone metastasis (HR = 2.78, 95%CI = 2.34-3.3) or concurrent bone and brain metastases (HR = 1.62, 95%CI = 1.03-2.55) had a higher mortality risk. Older age, gender, race, and single marital status were associated with bone metastasis and poorer prognosis in TC patients at initial diagnosis. Understanding such risk factors can potentially assist clinicians in making early diagnoses and personalized treatment plans, as well as researchers in developing more therapeutic protocols.

RESUMO

BACKGROUND AND AIMS: Basic life support (BLS) training rates vary widely worldwide, and there is a general scarcity of surveys that assess students' knowledge and awareness of BLS in middle eastern nations. This study aims to evaluate medical students' knowledge and awareness towards basic life support. METHODS: A cross-sectional study, using an online web-based questionnaire, assessing BLS awareness and knowledge, was conducted from 3 to 30 November 2021. The study included 2114 medical students from Syria, Iraq, and Jordan. The questionnaire consisted of three sections: demographic baseline characteristics, knowledge about BLS, and ability to apply basic life support. A binominal logistic regression was done between the total score and other demographic characteristics to determine if we could predict the research sample's appropriate knowledge of BLS level. RESULTS: There was a moderate knowledge of BLS and cardiopulmonary resuscitation (CPR) skills among participating students with an average score of 19.67 (0-34). Seventy-eight of the participants (1656) stated that they have not attended a basic life support course. There was a significant difference between the participants from different countries, where the mean score in Syria, Jordan, and Iraq was 18.3, 24.3, and 18.8, respectively (p < 0.05). Considering the level of knowledge, 18.3%, 72.8%, and 8.9% of the participants had a high, intermediate, and low level, respectively. Furthermore, students who took a BLS course had a higher level of knowledge than those who did not, with an odds ratio of 5.168 (p value < 0.0001). CONCLUSION: The overall knowledge of medical students' basic life support knowledge is insufficient and need to be greatly improved. According to this study, previous participation in basic life support training had a positive effect on knowledge level. As a result, universities must establish basic life support programs as quickly as possible.

RESUMO

PURPOSE: There is an increased demand for surgical solutions to treat craniocervical instability. This retrospective study demonstrates the clinical and radiological outcomes of unstable craniocervical junction treated with occipitocervical fusion. MATERIAL AND METHODS: The mean age of 52 females and 48 males was 56.89 years. The clinical and radiological outcomes were assessed, including NDI, VAS, ASIA score, imaging, complications and bony fusion in two used constructs: a modern occipital plate-rod-screw system (n = 59) and previous bilateral contoured titanium reconstruction plates-screws (n = 41). RESULTS: Clinically and on imaging, patients presented with neck pain, myelopathy, radiculopathy, vascular symptoms and craniocervical instability. The mean follow-up was 6.47 years. A solid bony fusion was achieved in 93.81% of the patients. The NDI and the VAS improved significantly from 28.3 and 7.67 at the presentation to 16.2 and 3.47 at the final follow-up. The anterior and posterior atlantodental interval (AADI and PADI), the clivus canal angle (CCA), the occipitoaxial angle (OC2A) and the posterior occipitocervical angle (POCA) improved significantly. Six patients required early revision. CONCLUSION: Occipitocervical fusion can yield excellent results regarding clinical improvement and long-term stability with a high fusion rate. Simple reconstruction plates, though more demanding surgically, achieve similar results. Preserving a neutral patient's position for fixation avoids postoperative dysphagia and may help prevent adjacent segment disease development.

RESUMO

Cranial irradiation is associated with several adverse events such as endocrinopathy, growth retardation, neurocognitive impairment, secondary malignancies, cerebral vasculopathy, and potential stroke. The better side effects profile of proton beam therapy compared with that of photon radiation therapy is due to its physical properties, mainly the sharp dose fall-off after energy deposition in the Bragg peak. Despite the better toxicity profile of proton beam therapy, the risk of  moyamoya syndrome still exists. We conducted a systematic review of the existing literature on moyamoya syndrome after receiving cranial radiation therapy for pediatric brain tumors to investigate the incidence of moyamoya syndrome after receiving photon versus proton radiation therapy. In this review, we report that the incidence of moyamoya syndrome after receiving proton beam therapy is almost double that of photon-induced moyamoya syndrome. Patients who received proton beam therapy for the management of pediatric brain tumors are more likely to develop moyamoya syndrome at the age of less than 5 years. Meanwhile, most patients with proton-induced moyamoya are more likely to be diagnosed within the first 2 years after the completion of their proton beam therapy.

RESUMO

Intracerebral hemorrhage (ICH) is the most lethal type of cerebral stroke without effective therapy. Although clinical trials with various surgeries have been conducted, none have improved clinical outcomes compared to the current medical management for ICH. Several ICH animal models, including autologous blood injection, collagenase injection, thrombin injection, and microballoon inflation methods, have been developed to elucidate the underlying mechanisms of ICH-induced brain injury. These models could also be used for discovering new therapy for ICH preclinically. We summarize the existing ICH animal models and the evaluation parameters used to measure the disease outcomes. We conclude that these models, resembling the different aspects of ICH pathogenesis, have their advantages and disadvantages. None of the current models closely represent the severity of ICH seen in clinical settings. More appropriate models are needed to streamline ICH's clinical outcomes and be used for validating newly developed treatment protocols.

RESUMO

AIM: The current work aims to demonstrate the potential defensive function of venlafaxine (VLF) in cardiotoxicity and nephrotoxicity caused by cisplatin (CP), that could be by modulating extracellular signal-regulated kinase (ERK)1/2 and nicotinamide adenine dinucleotide phosphate (NAPDH) oxidase NOX4 pathways. MAIN METHODS: Five groups of rats were used, as follow: three control groups (control, carboxymethyl cellulose, and VLF), CP group got CP once (7 mg/kg, intraperitoneally, i.p.), and (CP+ VLF) group got CP once then after 1 h they got VLF {50 mg/kg daily, orally for 14 days}. At the end of the study; electrocardiogram (ECG) was recorded for anaesthized rats then blood samples and tissues were taken for biochemical and histopathological investigations. Caspase 3, a marker of cellular damage and apoptosis was detected by immunohistochemistry. KEY FINDINGS: CP treatment significantly impaired cardiac functions as evidenced by changes in rats' ECG. Cardiac enzymes, renal markers and inflammatory markers were increased with decreased activities of the total antioxidant capacity, superoxide dismutase and glutathione peroxidase. Also, ERK1/2 and NOX4 were upregulated with histopathological and immunohistochemical alterations of heart and kidney. While, VLF markedly alleviated CP-induced functional cardiac abnormalities and improved ECG pattern. It reduced both cardiac and renal biomarkers, oxidative stress, proinflammatory cytokine with ERK1/2 and NOX4 downregulation, improved the histopathological and immunohistochemical changes induced by cisplatin in heart and kidney. SIGNIFICANCE: VLF treatment impedes cardiotoxicity and nephrotoxicity caused by CP. This beneficial effect was mediated through reduction of oxidative stress, inflammation, and apoptosis by targeting the ERK1/2 and NOX4.

RESUMO

In this study, the authors aimed to share their experience with 46 patients who were wounded due to terrorism and war in Somalia. The authors also evaluated the etiological diversity of terror-related and war-related injuries. The study included 46 patients treated at the 150-bed Turkey-Somalia Tertiary Hospital between 2019 and 2021. The authors reviewed medical records including data regarding age, sex, trauma etiology, and type of fracture and trauma. For all patients, surgical technique and plate and screw applications were recorded. The authors also assessed complications and outcomes for the patients. The study included 5 women (10.9%) and 41 men (89.1%). The mean age was 30.36 years. It was found that 2 patients (4.35%) presented to the emergency department with stab injuries, 33 patients with blast injuries from improvised explosive devices (71.73%), and 11 patients with firearm injuries. There were 31 patients with maxillary and mandibular fractures, 17 of which had both maxillary and mandibular fractures. There were 14 patients with maxillary fracture alone, including 3 patients with tripod fracture and 7 patients with inferior and lateral rim fracture. There was a mandibular fracture in 17 patients, including 5 patients with parasymphysis fracture, 7 patients with ramus fracture, and 5 patients with multifocal comminuted fracture. It is a challenging process to treat terror-related injuries in our tertiary hospital in Somalia, where all resources are imported from foreign countries. In such settings, authorities should make protective equipment obligatory to prevent civil and military casualties. Trauma hospitals and experienced trauma surgeons should be available.

RESUMO

Aims: Long non-coding RNAs (lncRNAs) contribute to the regulation of vital physiological processes and play a role in the pathogenesis of many diseases. Monocrotaline (MCT) can cause large-scale outbreaks of toxic liver disease in humans and animals in the form of hepatic sinusoidal obstruction syndrome (HSOS). Although many experiments have been carried out to explain the pathogenesis of Monocrotaline-induced hepatic sinusoidal obstruction syndrome and to develop treatments for it, no studies have examined the role of Long non-coding RNAs in this condition. This study aimed to investigate the Long non-coding RNAs-mRNA regulation network in Monocrotaline-induced hepatic sinusoidal obstruction syndrome in rats. Main methods: We established a model for MCT-induced hepatic sinusoidal obstruction syndrome, and then carried out microarray for liver tissues of SD rats in a model of early hepatic sinusoidal obstruction syndrome (12 h Monocrotaline treatment vs. control group) to investigate the differentially expressed Long non-coding RNAs and mRNAs in early hepatotoxicity. This was followed by RT-PCR analysis of selected Long non-coding RNAs, which were markedly altered. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genome analyses were also conducted. Key findings: 176 Long non-coding RNAs (63 downregulated and 113 upregulated) and 4,221 mRNAs (2,385 downregulated and 1836 upregulated) were differentially expressed in the Monocrotaline-treated group compared to the control group. The biological processes identified in GO enrichment analysis as playing a role in hepatotoxicity were positive regulation of guanosine triphosphate phosphohydrolase, liver development, and the oxidation-reduction process. Pathway analysis revealed that the metabolism pathways, gap junction, and ribosome biogenesis in eukaryotes were closely related to Monocrotaline-induced hepatotoxicity. According to these analyses, LOC102552718 might play an essential role in hepatotoxicity mechanisms by regulating the expression of inositol 1,4,5-trisphosphate receptor-1 (Itpr-1). Significance: This study provides a basis for further research on the molecular mechanisms underlying Monocrotaline-induced hepatotoxicity and its treatment, especially in the early stage, when successful treatment is critical before irreversible liver damage occurs.

RESUMO

Background: Though vaccines have been reported as highly efficacious in preventing severe COVID-19 disease, there is emerging data of severe infections, albeit a small number, in vaccinated individuals. We have conducted a retrospective observational study to assess the clinical characteristics, immunological response, and disease outcomes among the vaccinated and unvaccinated patients admitted to the ICU with severe COVID-19 disease. Methods: Study Design and Participants. We conducted a retrospective observational study in COVID ICU of a tertiary care hospital. Data were collected from the month of 1 April 2021 to 31 November 2021. All adult patients admitted to the ICU having severe COVID-19 disease were included in the study. Data were collected from the medical records database which included demographics, a clinical course in the ICU, laboratory and radiological parameters, and disease outcomes. In a subset of patients, cell-mediated immunity and S1S2-neutralising antibody assessment was done. Results: A total of 419 patients with severe COVID-19 were included in the study. Of the 419 patients, 90 (21.5%) were vaccinated, and 329 (78.5%) were unvaccinated. There was a significantly higher mortality in unvaccinated severe COVID 19 patients as compared to vaccinated severe COVID patients (46.2% vs 34.4%; P < 0.0455). The neutralizing antibody titre was significantly higher in survivors as compared to nonsurvivors (2139.8, SE ± 713.3 vs 471, SE ± 154.4); P < 0.026. Conclusion: Our study suggests the association of lower neutralizing antibody levels with mortality in ICU patients admitted with COVID-19 breakthrough infections.
