Coenurus cerebralis is the larval stage of Taenia multiceps which involves particularly the central nervous system of humans and ungulates. A six-month-old Charollais lamb was presented with cortical blindness, dullness, convulsion, head deviation, reluctancy to move, drooling of saliva and ataxia. Haematological findings revealed an inflammatory process. CSF analysis showed leukocytosis associated with increased total protein. By CT imaging, nine cysts were detected in the cerebrum and one in the cerebellum. Hounsfield units were below 10 in all these regions. CT images perfectly revealed multiple Coenurus cysts in various parts of the brain, which was confirmed by necropsy. At necropsy, cysts of variable size were noted at different anatomical sites of the brain. In the cerebrum, atrophy, liquefactive necrosis and mild demyelination were presenty adjacent to the cystic structures. Perivascular and perineuronal oedema, neuronal degeneration, hyperaemia and thrombosis were also seen in the cerebrum. The meninges revealed oedema, thrombosis, and mononuclear meningitis. Based on authors' knowledge, this is the first study in Iran on Coenurus cysts in a lamb brain utilising CT scan. [ABSTRACT FROM AUTHOR]

The objective of this study was to answer to these principal questions that whether a more homogeneous and purified colony of Human adipose-derived mesenchymal stem cells (hASCs) has significantly higher ability of differentiation in comparison to heterogeneous hASCs colony? And also is the any synergism between chemical and mechanical motivation of hASCs? For this purpose, CD-271+ hASCs were isolated by flow cytometry approach and their differentiation ability toward endothelial cells (ECs) was analyzed after application of mechanical shear stress and chemical growth factor. The results were compared to that of heterogeneous colony of hASCs. Abdominal adipose tissues were isolated from previously informed and consent 25-35 year old healthy women. A perfusion bioreactor was used for application of flow shear stress of magnitude of 4.64 dyne/cm2 purified and nonpurified hASCs which lie on collagen type I coated silicon scaffold. In addition to that, cells were exposed to 50 ng/ml vascular endothelial growth factor (VEGF) for 7 days. Three endothelial specific genes (FLK-1, vWF and VE-cadherin) were selected and their expressions in RNA level were assessed by real time PCR. Real time PCR results demonstrated that generally CD-271+ hASCs have more promising differentiation ability. Also it has been shown that highest expression of ECs specific genes is related to concurrent chemically and mechanically motivated hASCs. In conclusion, mechanical stimulation is at least as important as chemical stimulations and a more homogeneous group of hASCs could be regarded as a more convenient source of cells for vascular tissue engineering applications.

Lack of forage in semi-arid areas is one of the important issues in these areas. Cultivation of forages is effective terms to provide food of livestock in respect to rangeland condition and the high number of livestock. Obviously, it is necessary to identify cultivation circumstance and its approach based on plant physiological properties. We aimed to study the effects of time, depth, and sowing distance of Coronilla varia cultivation, seeds cultivated at three depth one, two and three cm and with distance of four, eight and twelve cm from each other at two level of times one and 15 march. The sextet growth characteristics investigated at 18 experiment unit during 15 weeks. The ANOVA based on Tukey's range test, results showed that cultivate treatments had significantly effect on the growth characteristics. The highest mean of stem height, length of leave, cross and height of branch and leave were recorded at sowing date of 15 March based on four cm distance and. Thereby, distance and sowing date has more effect related to depth. Distance of four cm and sowing date of 15 March provide better properties to growth for Coronilla varia. [ABSTRACT FROM AUTHOR]

Background: To examine macronutrient and micronutrient intake of adolescent girls of Tehran, capital of Iran to discover any malnutrition in relation to weight status and dieting.Methods: A cross-sectional study was conducted. Four hundred 11- to 17-year-old students were selected by multistage cluster sampling from secondary and high schools of Tehran. The information about dietary intakes was taken by food frequency questionnaire and 24-hour recall form. The students' body mass indices (BMIs) were measured and were classified according to National Center for Health Statistics /Center for Disease Control and Prevention (2000) growth charts. Participants were also questioned about body image and dieting. Results: 6.7% of adolescent girls were classified as being obese, 14.6% overweight, 75.4% normal and 3.2% underweight. Students 11-13 year old, had mean intakes lower than estimated average requirement (EAR) for folic acid, vitamin E, calcium, magnesium, phosphorus, potassium and sodium, and 14-18 year old students had mean intakes lower than EAR for niacin, pyridoxine, folic acid, pantothenic acid, vitamin E, calcium, magnesium, phosphorus, potassium, sodium and zinc. Obese and overweight adolescents had less carbohydrate, thiamin, niacin, iron and selenium intake. The participants, who were dieting, used significantly less amounts of proteins, carbohydrates, thiamin, niacin, iron, selenium, sodium and zinc.Conclusion: Knowing the harmful consequences of nutrient deficiency especially in adolescents, nutrition education must be emphasized in schools to promote nutritional literacy.

Snoring can occur alone or it may be the presenting feature of Obstructive Sleep Apnea and other common chronic conditions. In our study, we aimed to estimate the prevalence and correlates of snoring in adolescent students in Tehran, Iran. A cross-sectional study was designed and students were selected from 20 secondary and high schools, in 5 different zones in Tehran in order to have a representative sample of the adolescent population. A total of 2900 students (1200 male and 1700 female students) 11-17 year-old who were attending secondary and high schools were investigated. Information was collected via a structured face-to-face interview, based on a questionnaire. In addition to snoring, nocturnal cough, asthma-related symptoms, and daytime symptoms were also questioned. BMI was measured by two trained physicians. The prevalence of snoring was 7.9% (4.8% in girls and 12.4% in boys). The prevalence of snoring was significantly higher among males (P< 0.05). Snoring was positively associated with asthma and nocturnal cough. Overweight/obese adolescents had significantly higher rates of snoring and asthma symptoms. Prevalence of daytime symptoms increased significantly in the snoring group. These results suggest that snoring is associated with multiple factors in adolescents. We conclude that the prevalence of snoring is relatively high in children of this region. This highlights the need for awareness among physicians about the problem of sleep-disordered breathing, especially in children with asthma and obesity, and also the need for further studies to measure the prevalence of sleep breathing disorders among Iranians.

Female adolescents and adults are among the population groups who are most affected by iron deficiency. Thus, the aim of this study was to investigate the prevalence of iron deficiency and iron deficiency anaemia in female students aged 18 to 25 years old from the Tehran University of Medical Sciences, Iran.295 female university students participated in the study. The mean corpuscular volume (MCV) and haemoglobin (Hb), serum ferritin, serum iron and total iron binding capacity (TIBC) levels were measured. Iron deficiency anaemia was defined as a situation where Hb is less than 12 g/dL, MCV is less than 78 microm3, ferritin is less than 12 ng/ml or transferin saturation (TS) (iron/TIBC x 100) is less than 15 percent, Iron deficiency (ID) was defined as a situation where Hb is greater than or equal to 12 g/dL, MCV is greater than or equal to 74 microm3, ferritin is less than 12 ng/ml or TS is less than 15 percent.The complete data was available for 237 students. The prevalence of ID was 40.9 percent and that of IDA was 3.8 percent. Normal iron status was found in 49.8 percent of the subjects. The remaining (5.5 percent) had other kinds of anaemia or required confirmatory tests.ID is common among 18 to 25-year-old Iranian female university students. Iron supplementation is thus required for the target group.

Abstract Kimura's disease is a rare, benign, slow growing chronic inflammatory swelling with a predilection for the head and neck region and almost always with peripheral blood eosinophilia and elevated serum IgE levels. Here, we report a 25-year-old male patient with asthma, Reynaud phenomenon, eosinophilic panniculitis, bilateral inguinal lymphadenopathy and peripheral blood eosinophilia. He responded initially to oral prednisolone with the subsidence of peripheral blood eosinophilia, asthma and the Reynaud phenomenon. But with tapering of prednisolone symptoms reappeared and hereby he was treated with cyclosporine. He has been symptom free for 6 months of follow up while taking cyclosporine 25 mg orally per day. Eosinophilia has resolved. This case shows that in addition to previously reported associations, Kimura disease may be associated with eosinophilic panniculitis and that cyclosporine could be effective in its treatment.

Recent studies on the pathophysiology of COVID-19 are indicating that the Angiotensin convertase enzyme 2 (ACE-2) and transmembrane serine protease 2 (TMPRSS2) can act as a major component in the fusion of SARS-Cov-2 with target cells. It has also been observed that the expression of ACE-2 and TMPRSS2 can be altered in malignancies. Shedding light on this matter could be crucial since the COVID-19 pandemic interfered with many gastrointestinal cancer screening programs. Herein we discuss the possibility of severe forms of COVID-19 in patients with gastrointestinal cancers due to the gastrointestinal entry route of SARS-CoV-2 into the human body. The disruption of cancer screening programs caused by the current COVID-19 pandemic could therefore have massive negative health impact on patients affected by gastrointestinal malignancies.

Background Granulomatosis with polyangiitis (GPA), also known as Wegener’s granulomatosis, is an idiopathic systemic disease typically affecting the lungs, although other organs may also be involved. Case presentation A 28-year-old male was admitted to Baqiyatallah university hospital in Teheran (Iran) after a 3-week history of fever and productive cough. The patient gradually developed fatigue, arthralgia, hematuria, nausea, vomiting, dyspnea, hemoptysis, weight loss, oliguria and then anuria. Chest-X-ray (CXR) and computerized tomography scan revealed cavitating nodular opacities in the right lung lobe. Furthermore, plasma creatinine increased from 2.2 to 4 mg/dl in a few days. Histopathological examination of kidney biopsy revealed peri-glomerular and peri-vascular inflammation, degeneration and necrosis of the tubular epithelial lining, red blood cell casts, distorted glomerular structure, fibrin thrombi, segmental breaks of the glomerular basal membrane, disruption of Bowman's capsular membrane and crescent formation of the affected glomeruli. An abnormal CXR, an abnormal urinary sediment and a typical kidney histology were used as criteria to diagnose glomerulonefritis with poliangiitis (GPA). Bronchoalveolar lavage smear and PCR turned out positive for mycobacterium tuberculosis. After 3 months of treatment for (GPA) and tuberculosis the patient developed headache and seizure. Cerebral Magnetic Resonance Venography revealed cerebral venous thrombosis of the sinus transverse and sigmoid. Conclusions Tuberculosis may coexist with GPA, as it occurred in our patient. Since a crescentic glomerulonephritis can progress to renal failure, clinicians should always be aware of potential multiple conditions when considering differential diagnoses.

- Abstract
Background: Research on incidence and characteristics of Out-of-Hospital Cardiac Arrest (OHCA) in the Middle East is limited. We assessed the incidence, prehospital characteristics, and outcomes of OHCA in Qatar, a Middle Eastern country. Subsequently, we performed gender-specific analysis., Methods: This was a retrospective examination of data obtained from the OHCA registry at Hamad Medical Corporation (HMC) in Qatar from 2017 to 2022. We included adults, non-traumatic, EMS-treatment OHCA. We calculated the incidence of adult OHCA and conducted descriptive analyses for prehospital characteristics, and prehospital outcomes presented by return of spontaneous circulation (ROSC). We evaluated gender differences in prehospital characteristics and ROSC using Student's t-test and the Chi-Square test as appropriate. Furthermore, we conducted a multivariable logistic regression analysis to investigate the correlation between gender and achieving ROSC., Results: We included 4,306 adult OHCA patients, with 869 (20.2%) being females. The mean annual incidence of adult OHCA was 27.4 per 100,000 population-year. Males had a higher annual incidence of OHCA than females. Among all cases, 36.3% occurred in a public location, 25.8% had an initial shockable rhythm, and 28.8% achieved ROSC. Males had a higher proportion of bystander CPR, arrests in public locations, and initial shockable rhythms. While unadjusted analysis showed no significant gender differences in achieving ROSC, adjusted analysis revealed that male gender was associated with higher odds of achieving ROSC (adjusted OR male vs. female 1.38, 95% CI 1.15-1.66, p < 0.001)., Conclusions: Approximately 720 adults undergo non-traumatic OHCA in Qatar every year, with a higher incidence observed in males. Male gender was associated with higher odds of achieving ROSC. Further gender-specific research in OHCA intervention and outcome in the Middle East is required., (© 2024. The Author(s).)

- Abstract
We aimed to assess the diagnostic performance of Cardiac Magnetic Resonance (CMR) strain parameters in ACM patients to evaluate their diagnostic role. We systematically searched MEDLINE, EMBASE, Scopus, and Web of Science. Of the 146 records, 16 were included. All Right Ventricle (RV) global strains were significantly reduced in ACM patients compared to controls (Standardized Mean Difference (SMD)[95 % Confidence Interval (CI)]: Longitudinal 1.31[0.79,1.83]; Circumferential 0.88[0.34,1.42]; Radial -1.14[-1.78,-0.51]). Similarly, all Left Ventricle (LV) global strains were significantly impaired in ACM compared to healthy controls (SDM [95 %CI]: Longitudinal 0.88[0.48,12.28], Circumferential 0.97[0.72,1.22], Radial -1.24[-1.49,-1.00]). Regarding regional RV strains, longitudinal and circumferential strains were significantly reduced in basal and mid-wall regions, while they were comparable to controls in the apical regions. The RV radial strain was reduced only within the basal region in the ACM group compared to controls. ACM patients exhibited significant impairment of regional LV strains in all regions-basal, mid-wall, and apical-compared to control subjects. Ultimately, despite the limitations of CMR-FT in terms of reproducibility, it is superior to qualitative assessment in detecting wall motion abnormalities. Thus, integrating CMR-FT with ACM diagnostic criteria seems to enhance its diagnostic yield., 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., (© 2024 Published by Elsevier B.V.)

- Abstract
Introduction: Immature Platelet Fraction (IPF) is a measure of the proportion of reticulated platelets (RPs) to all platelets in circulation. IPF may have both prognostic and diagnostic values in patients with Acute Coronary Syndrome (ACS). This study aims to comprehensively summarize the diagnostic utility of IPF levels in patients with ACS, specifically focusing on its ability to differentiate between different subtypes of ACS., Methods: We conducted a systematic search in online databases including MEDLINE, Scopus, and Google Scholar up to March 4
th 2024, to identify relevant studies. The random-effect model, employing inverse variance for mean differences (MD) and Mantel-Haenszel methods for odds ratios (OR) were utilized to combine the data. Joanna Briggs Institute (JBI) appraisal tool was employed to assess the quality of included studies., Results: Our systematic review contains 15 articles with a total sample size of 2,030 ACS patients. Pooled analysis revealed significant differences in IPF levels of ACS patients compared to healthy controls (MD (95%CI): 2.85 (0.86, 4.85), P-value = 0.004) and stable angina patients (MD (95%CI): 0.58 (0.23, 0.92), P-value < 0.001). Subgroup comparisons within ACS patients demonstrated higher IPF levels in myocardial infarction (MI) vs. unstable angina (UA) (MD (95%CI): 1.81 (0.41, 3.22), P-value = 0.01), ST elevation MI (STEMI) vs. non-ST elevation (NSTEMI) ACS (MD (95%CI): 0.74 (0.31, 1.17), P-value < 0.001), and NSTEMI vs. UA (MD (95% CI): 1.07 (0.24, 1.90), P-value = 0.01)., Conclusion: IPF levels could increase in patients with ACS, particularly during the acute phase of STEMI. This suggests that IPF may be a useful biomarker for early diagnosis of ACS. Additionally, IPF levels may help differentiate between ACS subtypes., Competing Interests: The authors declare that there are no conflicts of interest.- Published

- Abstract
Introduction: Currently, epicardial coronary angiography is still the only diagnostic tool for Coronary Slow Flow Phenomenon (CSFP). This study aimed to systematically review studies that compared Electrocardiogram (ECG) findings between patients with and without CSFP., Methods: Using relevant key terms, we systematically searched MEDLINE, Scopus, Embase, and Web of Science to find relevant studies up to February 5
th , 2023. Effect sizes in each study were calculated as mean differences and crude odds ratio; then, random-effect models using inverse variance and Mantel-Haenszel methods were used to pool standardized mean differences (SMD) and crude odds ratios, respectively., Results: Thirty-two eligible articles with a total sample size of 3,937 patients (2,069 with CSFP) were included. CSFP patients had higher P-wave maximum (Pmax) (SMD: 1.02 (95% confidence interval (CI): 0.29 - 1.76); p=0.006) and P-dispersion (Pd) (SMD: 1.63 (95% CI: 0.99 - 2.27); p<0.001) compared to the control group. CSFP group also showed significantly longer QT wave maximum duration (SMD: 0.69 (95% CI: 0.33 - 1.06); p<0.001), uncorrected QTd (SMD: 1.89(95% CI: 0.67 - 3.11); p=0.002), and corrected dispersion (QTcd) (SMD: 1.63 (95% CI: 1.09 - 2.17), p<0.001). The frontal QRS-T angle was significantly higher in the CSFP group in comparison with the control group (SMD: 1.18 (95% CI: 0.31 - 2.04; p=0.007). While CSFP patients had a significantly higher T-peak to T-end (Tp-e) (SMD:1.71 (95% CI: 0.91, 2.52), p<0.001), no significant difference was noted between groups in terms of Tp-e to QT (p=0.16) and corrected QT ratios (p=0.07)., Conclusion: Our findings suggest several ECG parameters, such as P max, Pd, QT, QTc, QTd, QTcd, Tp-e, and frontal QRS-T angle, may be prolonged in CSFP patients, and they could be employed as diagnostic indicators of CSFP before angiography., Competing Interests: Authors declare no conflict of interest.- Published

- Abstract
Background: The no-reflow phenomenon affects about one out of five patients undergoing Primary Percutaneous Coronary Intervention (PPCI). As the prolonged no-reflow phenomenon is linked with unfavorable outcomes, making early recognition is crucial for effective management and improved clinical outcomes in these patients. Our review study aimed to determine whether electrocardiogram (ECG) findings before PCI could serve as predictors for the occurrence of the no-reflow phenomenon., Methods and Materials: We systematically searched MEDLINE, Scopus, and Embase to identify relevant studies. The random-effect model using inverse variance and Mantel-Haenszel methods were used to pool the standardized mean differences (SMD) and odds ratios (OR), respectively., Result: Sixteen eligible articles (1,473 cases and 4,264 controls) were included in this study. Based on our meta-analysis of baseline ECG findings, the no-reflow group compared to the control group significantly had a higher frequency of fragmented QRS complexes (fQRS) (OR (95% CI): 1.35 (0.32-2.38), P -value = 0.01), and Q-waves (OR (95% CI): 1.97 (1.01-2.94), P -value <0.001). Also, a longer QRS duration (QRSD) (SMD (95% CI): 0.72 (0.21, 1.23), p -value <0.001) and R wave peak time (RWPT) (SMD (95% CI): 1.36 (0.8, 1.93), P < 0.001) were seen in the no-reflow group. The two groups had no significant difference regarding P wave peak time (PWPT), and P wave maximum duration (Pmax) on baseline ECG., Conclusion: Our findings suggest that prolonged QRSD, delayed RWPT, higher fQRS prevalence, and the presence of a Q wave on baseline ECG may predict the occurrence of the no-reflow phenomenon in patients undergoing PPCI., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Jafari Afshar, Gholami, Samimisedeh, MozafaryBazargany, Tayebi, Memari, Yazdani and Rastad.)

- Abstract
Purpose: Neutropenic fever remains a major complication in acute leukemia. Decolonization is assumed as a promising intervention for eradicating causative agents of infection., Methods: In this randomized clinical trial, 96 patients with acute leukemia were assigned randomly to mupirocin nasal drop 2% (n = 32), chlorhexidine mouthwash 0.2% (n = 33), and control group (n = 31). In control group, patients did not receive any medication for decolonization. All patients received treatment for 5 days (2 days prior to chemotherapy until 3 days after chemotherapy). Pharynx and nasal swabs were taken prior to the intervention and at the end of decolonization period in all groups. Antibiotic susceptibility testing was performed by the disc diffusion method in order to identify bacterial isolates., Results: Bacterial recovery of both nasal and pharynx swabs was observed after global decolonization with mupirocin nasal drop. Decolonization with mupirocin significantly eradicated Coagulase-negative staphylococci (CONS) in both nasal and pharynx swabs (p-value = 0.000). Moreover, mupirocin decreased Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) species. Chlorhexidine mouthwash significantly eradicated CONS in pharynx swabs (p-value = 0.000). In addition, both decolonization strategies decreased both antibiotic use and frequency of fever in leukemic patients., Conclusion: Global decolonization with mupirocin nasal drop not only eradicates both nasal and pharynx microorganisms, but also reduces antibiotic requirement and frequency of fever in patients with acute leukemia. The protocol of the present study was approved on December 2016 (registry number: IRCT20160310026998N6)., (© 2023.

- Abstract
Introduction: Vincristine is a vesicant chemotherapeutic agent which may leak from the vessel at the infusion site to the perivascular tissue and cause extravasation. Extravasation, a severe complication of chemotherapeutic drugs, can result in tissue necrosis that is considered an oncological emergency., Case Report: We aimed to report a case of a 29-year-old woman with ALL-B cell (Acute lymphoblastic leukemia) on maintenance chemotherapy regimen including vincristine, methotrexate, prednisolone, and 6-mercaptopurine (POMP). 48 h after administering intravenous vincristine, the patient experienced burning, pain and tenderness at the injection site (left hand - cubital cavity)., Management & Outcome: 7 days after the onset of symptoms, the patient was hospitalized with a large brown lesion at the site. She was prescribed betamethasone cream, DSMO (Dimethyl sulfoxide) solution, and oral levofloxacin on his second day after admission. The lesion was completely improved 10 days after initiation of therapy and there were no serious problems., Discussion: Due to the ineffectiveness of antidote therapy for the management of delayed extravasation of vincristine and beneficial effect of our clinical approach, it could consider for the management of similar cases with delayed extravasation following vincristine administration., 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.

- Abstract
Introduction and Importance: Acetabular fractures mostly occur in young people who are involved in high-energy trauma and they are treated by orthopedic trauma surgeons. Patients with acetabular fractures are at high risk for different kinds of complications. We report a case of postoperative thrombosis of the external iliac artery following fixation surgery performed by an ilioinguinal approach while receiving thromboprophylaxis during admission to the hospital., Case Presentation: A 57-year-old healthy woman presented with a left both-column acetabular fracture and underwent acetabular fixation through the ilioinguinal approach. The patient was receiving antithrombotic prophylaxis medications in the course of treatment., Clinical Discussion: During her convalescence, while at the hospital, she was diagnosed with left external iliac artery thrombosis, needing surgical thrombectomy. These severe and rare complications will lead to uncertainty about a commonly used ilioinguinal approach. Postoperative arterial thrombosis may be rare in patients undergoing acetabular fixation surgery but searching for signs and symptoms of this condition is always necessary., Conclusion: It is possible to prevent severe complications by performing a routine measurement of the distal arterial pressure after similar surgeries., Competing Interests: The authors declare no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2023 The Author(s).

- Abstract
Objective: To compare psychiatric emergencies and self-harm at emergency departments (EDs) 1 year into the pandemic, to early pandemic and pre-pandemic, and to examine the changes in the characteristics of self-harm presentations., Method: This retrospective cohort study expanded on the Pandemic-Related Emergency Psychiatric Presentations (PREP-kids) study. Routine record data in March to April of 2019, 2020, and 2021 from 62 EDs in 25 countries were included. ED presentations made by children and adolescents for any mental health reasons were analyzed., Results: Altogether, 8,174 psychiatric presentations were recorded (63.5% female; mean [SD] age, 14.3 [2.6] years), 3,742 of which were self-harm presentations. Rate of psychiatric ED presentations in March to April 2021 was twice as high as in March to April 2020 (incidence rate ratio [IRR], 1.93; 95% CI, 1.60-2.33), and 50% higher than in March to April 2019 (IRR, 1.51; 95% CI, 1.25-1.81). Rate of self-harm presentations doubled between March to April 2020 and March to April 2021 (IRR, 1.98; 95% CI, 1.68-2.34), and was overall 1.7 times higher than in March to April 2019 (IRR, 1.70; 95% CI, 1.44-2.00). Comparing self-harm characteristics in March to April 2021 with March to April 2019, self-harm contributed to a higher proportion of all psychiatric presentations (odds ratio [OR], 1.30; 95% CI, 1.05-1.62), whereas female representation in self-harm presentations doubled (OR, 1.98; 95% CI, 1.45-2.72) and follow-up appointments were offered 4 times as often (OR, 4.46; 95% CI, 2.32-8.58)., Conclusion: Increased pediatric ED visits for both self-harm and psychiatric reasons were observed, suggesting potential deterioration in child mental health. Self-harm in girls possibly increased and needs to be prioritized. Clinical services should continue using follow-up appointments to support discharge from EDs., Diversity & Inclusion Statement: One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science.

- Abstract
Introduction and Importance: The Masquelet technique remains one of the procedures with low rates of failure and infection. The use of this technique in humeral defects is still rare., Case Presentation: A 38-year-old male patient with an open humeral comminuted fracture induced by shotgun injury was referred to our hospital. The Masquelet technique was chosen as the best option with a lower risk of infection and the lower expenses at this stage due to the second time of open reduction and internal fixation and bone graft failure, low patient compliance, and the increasing size of the defect due to bone absorption. An arthrodesis procedure was performed 5 days after the second Masquelet stage as restoring the elbow joint's range of motion was impossible., Clinical Discussion: The Masquelet technique, is a two-step surgical procedure to manage pseudoarthroses and bone defects. Various surgical options are available for performing this procedure. There are several reasons behind the rising popularity of this technique during recent years. Some of these reasons include the reproducibility of this technique, as well as requiring less time, not being technically challenging, and having fewer neurovascular complications., Conclusion: This case was one of the limited examples of successful implementation of the Masquelete procedure on severe traumatic injuries of the upper limb with bone defects providing more evidence on the safety and efficacy of this technique in similar conditions., Competing Interests: The authors declare that they have no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2023 The Author(s).

- Abstract
Inferior dislocation of the hip is the rarest type of hip dislocation, mainly occurring from high-energy incidents, mostly from road traffic accidents or sports. It is generally an injury among adults., Case Presentation: A 17-year-old male sustained injuries as a pedestrian, and a 30-year-old male sustained a traffic accident as a motorcycle rider. Both patients complained of severe pain in the hip, decreasing range of motion, and the inability to weight bearing. In both, the affected hip joint was fixed in 90° flexion, abduction, and external rotation, and the leg was slightly shorter than the other limb. An X-ray showed the inferior dislocation of the right hip and left hip, respectively, without any sign of fracture. We reduced both dislocations closely after sedation without any complications during follow-ups., Conclusion: This injury should be treated as an emergency, and reduction performed as soon as possible, within 6 h. It can be managed usually with closed reduction under general anesthesia. Close follow-up is necessary to prevent its complications, including avascular necrosis, associated fractures, neurovascular compromise, and articular cartilage injuries., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 The Author(s).

- Abstract
Introduction: Calyx bearing vestibular afferent neurons innervating type I hair cells in the striolar region of the utricle are exquisitely sensitive to auditory-frequency air conducted sound (ACS) and bone conducted vibration (BCV). Here, we present experimental data and a mathematical model of utricular mechanics and vestibular compound action potential generation (vCAP) in response to clinically relevant levels of ACS and BCV. Vibration of the otoconial layer relative to the sensory epithelium was simulated using a Newtonian two-degree-of-freedom spring-mass-damper system, action potential timing was simulated using an empirical model, and vCAPs were simulated by convolving responses of the population of sensitive neurons with an empirical extracellular voltage kernel. The model was validated by comparison to macular vibration and vCAPs recorded in the guinea pig, in vivo., Results: Transient stimuli evoked short-latency vCAPs that scaled in magnitude and timing with hair bundle mechanical shear rate for both ACS and BCV. For pulse BCV stimuli with durations <0.8 ms, the vCAP magnitude increased in proportion to temporal bone acceleration, but for pulse durations >0.9 ms the magnitude increased in proportion to temporal bone jerk. Once validated using ACS and BCV data, the model was applied to predict blast-induced hair bundle shear, with results predicting acute mechanical damage to bundles immediately upon exposure., Discussion: Results demonstrate the switch from linear acceleration to linear jerk as the adequate stimulus arises entirely from mechanical factors controlling the dynamics of sensory hair bundle deflection. The model describes the switch in terms of the mechanical natural frequencies of vibration, which vary between species based on morphology and mechanical factors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Pastras, Gholami, Jennings, Zhu, Zhou, Brown, Curthoys and Rabbitt.)

- Abstract
Constipation is a common reason for children seeking medical care worldwide. Abdominal complaints and constipation are also common in lead-poisoned children. This study evaluates the prevalence of abnormal blood lead levels (BLL) among pediatric and adolescent patients and examines the association of constipation with elevated BLL. This was a prospective data collection of patients younger than 18 years old with the chief complaint of constipation seen in the Mofid Children's Hospital gastroenterology clinic and Loghman Hakim pediatric and pediatric gastroenterology clinics were eligible for enrollment in this study. Constipation was defined as infrequent or difficult defecation according to ROME IV criteria lasting 2 months or more. BLL was measured with a fresh capillary whole blood capillary sample. The LeadCare II device assays BLL using an electrochemical technique (anodic stripping voltammetry). A total of 237 patients were enrolled in the study. 122 (51.48%) were female and 115 (48.52%) were male. About one fifth of patients (49; 20.67%) had BLL ≥ 5 µg/dL. The mean BLL in the sample was 3.51 µg/dL. Abdominal pain was the most common symptom accompanying constipation (134; 56%). Multivariate analysis found endoscopic evaluation (P values 0.024, OR 3.646, 95% CI 1.189-11.178), muscle pain (P values 0.020, OR 24.74, 95% CI 1.67-365.83), and maternal education (P values 0.02, OR 4.45, 95% CI 1.27-15.57) with significant differences in groups of patients with normal and elevated BLL. Elevated BLL necessitates an assessment and plans to reduce childhood lead exposure. BLL screening in childhood constipation with refractory chronic abdominal pain may also eradicate the need for invasive procedures like endoscopic evaluation., (© 2023. The Author(s).)

- Abstract
Recently, Fe-Mn-based alloys have been increasingly catching the attention of the scientific community, because of their tunable and outstanding mechanical properties, and suitable degradation behavior for biomedical applications. In spite of these assets, their corrosion rate (CR) is, in general, too low to satisfy the requirements that need to be met for cardiovascular device applications, such as stents. In fact, the CR is not always the same for all of the degradation stages of the material, and in addition, a finely tuned release rate, especially during the first steps of the corrosion pattern, is often demanded. In this work, a resorbable bimodal multi-phase alloy Fe-3Mn-1Ag was designed by mechanical alloying and spark plasma sintering (SPS) to accelerate the corrosion rate. The presence of several phases, for example α-Fe, α-Mn, γ-FeMn and Ag, provided the material with excellent mechanical properties (tensile strength UTS = 722 MPa, tensile strain A = 38%) and a higher corrosion rate (CR = 3.2 ± 0.2 mm/year). However, higher corrosion rates, associated with an increased release of degradation elements, could also raise toxicity concerns, especially at the beginning of the corrosion pattern. In this study, The focus of the present work was the control of the CR by surface modification, with nitrogen plasma immersion ion implantation (N-PIII) treatment that was applied to mechanically polished (MP) samples. This plasma treatment (PT) improved the corrosion resistance of the material, assessed by static degradation immersion tests (SDITs), especially during the first degradation stages. Twenty-eight days later, the degradation rate reached the same value of the MP condition. Nitrogen compounds on the surface of the substrate played an important role in the corrosion mechanism and corrosion product formation. The degradation analysis was carried out also by potentiodynamic tests in modified Hanks' balanced salt solution (MHBSS), and Dulbecco's phosphate buffered saline solution (DPBSS). The corrosion rate was higher in MHBSS for both conditions. However, there was no significant difference between the corrosion rate of the PT in DPBSS (CR = 1.9 ± 0.6 mm/year) and in MHBSS (CR = 2 ± 1.4 mm/year). The cell viability was assessed with human vein endothelial cells (HUVECs) via an indirect metabolic activity test (MTT assay). Due to the lower ion release of the PT condition, the cell viability increased significantly. Thus, nitrogen implantation can control the in vitro corrosion rate starting from the very first stage of the implantation, improving cell viability.

- Abstract
Immune checkpoint inhibitors (ICIs) targeting programmed cell death-1 (PD-1 or CD279) have noticeably improved the treatment landscape of advanced cancer patients. Nivolumab, the most well-known genetically engineered anti-PD-1 monoclonal antibody (mAb), promotes anti-tumor immunity and shows excellent capability for treating various cancers, particularly lung cancer, renal cancer, and melanoma. Systemic administration of nivolumab could inspire durable therapeutic responses not typically seen with traditional cytotoxic anti-cancer agents. However, nivolumab monotherapy is ineffective in 60-70 percent of patients. The mechanisms leading to both primary and acquired resistance to PD-1/PD-L1 inhibition are varied and multifactorial. Recently, the rationality of adding other conventional therapies such as chemo-radiotherapy and targeted therapies such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and VEGF/VEGFR inhibitors to nivolumab has strongly been verified. These regimens overcome cancer resistance and thus boost nivolumab efficacy in cancer patients. Herein, we discuss the current status of the combination therapy with nivolumab in cancer patients, with a particular focus on the recent clinical reports., 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 © 2022 Elsevier B.V.

- Abstract
Recent advances in omics technology have prompted extraordinary attempts to define the molecular changes underlying the onset and progression of a variety of complex human diseases, including cancer. Since the advent of sequencing technology, cancer biology has become increasingly reliant on the generation and integration of data generated at these levels. The availability of multi-omic data has transformed medicine and biology by enabling integrated systems-level approaches. Multivariate signatures are expected to play a role in cancer detection, screening, patient classification, assessment of treatment response, and biomarker identification. This review reports current findings and highlights a number of studies that are both novel and groundbreaking in their application of multi Omics to prostate cancer., (© 2022. The Author(s).)

- Abstract
The COVID-19 outbreak affected mental health globally. One of the major concerns following the COVID-19 pandemic was increased incidence of risky behaviors including alcohol consumption. This study evaluates the trend of alcohol poisoning in Loghman-Hakim Hospital (LHH), the main referral center of poisoning in Tehran, during the 2-year period from 1 year prior to 1 year after the onset (February 23rd, 2020) of the COVID-19 epidemic in Iran. All patients admitted with alcohol intoxication from February 23rd, 2019 to February 22nd, 2021 were evaluated and patient data extracted from LHH electronic hospital records. Alcohols were categorized as toxic (methyl alcohol) and non-toxic (ethyl alcohol). Of 2483 patients admitted, 796/14,493 (5.49%) and 1687/13,883 (12.15%) had been hospitalized before and after the onset of the COVID-19 epidemic in Iran, respectively. In total, 140 patients did not survive, of whom 131 (93.6%) were confirmed to have methanol intoxication. Mortality was significantly higher during the outbreak (127 vs 13; P < 0.001; OR: 4.90; CI 95%: 2.75 to 8.73). Among the patients, 503 were younger than age 20. Trend of alcohol intoxication showed increases in children (57 vs 17) and adolescents (246 vs 183) when compared before and after the COVID-19 epidemic outbreak. A total of 955 patients were diagnosed with methanol toxicity which occurred more frequently during the COVID-19 era (877 vs 78; P < 0.001; OR: 10.00; CI 95%: 7.75 to12.82). Interrupted time series analysis (April 2016-February 2021) showed that in the first month of the COVID-19 epidemic (March 2020), there was a significant increase in the alcohol intoxication rate by 13.76% (P < 0.02, CI = [2.42-24.91]). The trend of alcohol intoxication as well as resulting mortality increased in all age groups during the COVID-19 epidemic in Iran, indicating urgent need for the prevention of high-risk alcohol use as well as improved treatment., (© 2022.

- Abstract
Hospital-treated intentional self-poisoning is common. The possibility of changed (increased) suicidal behaviors during the COVID-19 pandemic has been raised. To compare frequencies in self-poisoning events (SPEs) and the proportions with in-hospital mortality, in the year prior to and following the official onset of the COVID-19 pandemic, in a population of hospital-treated self-poisoning patients in Iran. All self-poisoned patients admitted to Loghman-Hakim Hospital, a clinical toxicology specialty hospital in Tehran, were included. The frequency of SPEs was compared between the one-year periods immediately before and after the onset of COVID-19 pandemic using Poisson regression. Differences in proportions of in-hospital mortality were also compared using logistic regression. A total of 14,478 patients with 15,391 SPEs (8,863 [61.2%] females) were evaluated in the study. There was no difference in the overall frequency of SPEs (relative risk [RR] of 0.99 [CI95% 0.96-1.03]), but a small increase in males (RR 1.07; 1.02-1.13) and a minor decrease in females (RR 0.95; 0.91-0.99). In total, 330 patients died (2.3% of all SPEs). There was no difference in overall in-hospital mortality odds ratio (OR: 0.98 [0.79-1.22]), in females (OR = 1.14 [0.80-1.60]) or males (OR = 0.92 [0.69-1.23]). There was no change in the frequency of SPEs and no difference in the in-hospital mortality proportions, suggesting that the COVID-19 pandemic had little or no effect on these aspects of suicidal behavior in Iran., Supplementary Information: The online version contains supplementary material available at 10.1007/s12144-022-03248-y., Competing Interests: Conflict of InterestsThe authors declare that they have no competing interests., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

The effective medical applications of cold atmospheric pressure plasma jet (APPJ) have been reported by many researchers, including sterilization of liquid and solid surfaces, treatment of chronic wounds, treatment of cancer tumors, and blood clots. Therefore, in this study, we exposed Aporrectodea trapezoides and Eisenia fetida earthworms to APPJ discharge (0-30 s) to evaluate the impacts on regeneration of missed segments, apoptosis, lipid peroxidation (LPo), catalase activity (CAT), total antioxidant capacity (TAC), total proteins, and protein profile. Results showed APPJ induced significant effects on regeneration ability of earthworms after 20 and 30 s of exposure (p < 0.05). Atmospheric pressure plasma jet did not have significant effects on MDA content and TUNEL-positive cells, but this effect was significant for TAC and CAT in both species (p < 0.05). In conclusion, the present study revealed for the first time that regeneration of missed segments in earthworms can be stimulated by plasma treatment., (© 2021.

- Abstract
Background: Acute poisoning is a significant and preventable cause of mortality among children internationally. The aims of this study were to assess the case fatality rate of children admitted to an inner-city hospital for acute poisoning and to compare the demographics and source of poisoning of fatal cases., Methods: This was a retrospective review of patient data recorded in the Hospital Information System for Loghman Hakim Hospital, that is, the central referral hospital for poisoning in Tehran, Iran. We searched Hospital Information System for all admissions for poisoning in children (age, 0-12 years) over the 10-year period from March 2010 to March 2020, and all cases were included in the analysis. We determined the case fatality rate by dividing the number of fatal cases by the number of included cases., Results: Of 8158 children admitted for poisoning, 28 cases (0.3%) died, among whom 19 (67.9%) were boys and 9 (32.1%) girls. The median age was 42 months, ranging from 2 to 144 months. Twenty-two cases (78.6%) were 0 to 5 years old. The most common cause of mortality in acute poisoning was methadone (n = 13, 46.4%), followed by raw opium (n = 5, 17.9%), aluminum phosphide, carbon monoxide, and wild mushrooms (n = 2 deaths each, 7.1%). Tramadol, colchicine, and petroleum accounted for 1 death each (3.6%)., Conclusions: Mortality from unintentional poisoning disproportionately affects children younger than 5 years. Opioids (ie, methadone, opium, tramadol) accounted for two thirds of deaths in our sample. Our findings highlight the importance of educating parents that any toxic materials (licit or illicit) must be stored out of reach for children., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: Lead exposure is one of the most menacing of environmental exposures, particularly in children. Children are more susceptible to the effects of lead which manifest in many organ systems, including interference with mental and motor development. Lead poisoning can cause colicky abdominal pain. In this study, the authors sought to evaluate the prevalence of elevated blood lead level (BLL) and its contributing factors among pediatric patients presenting with abdominal pain. An epidemic of lead poisoning in adults was previously uncovered, and thus a concern for pediatric lead poisoning was raised., Methods: Pediatric patients presenting to two pediatric clinics in Tehran with abdominal pain were eligible for enrollment in a descriptive prospective cross-sectional study. A predesigned questionnaire was filled for each patient by their consenting parents. The questionnaire queried demographic information, environmental, social, and other relevant parameters for lead exposure. After completion of the questionnaire, biometrics were obtained, and a blood sample was taken from each patient for measurement of BLL and complete blood count., Results: A total of 187 patients were enrolled in the study. Of them, almost 20% had BLL ≥ 5 µg/dL. Univariate analysis showed that age (p = 0.002, OR 3.194, CI 95% 1.504-6.783), weight (p = 0.009, OR 2.817, CI 95% 1.266-6.269), height (p = 0.003, OR 3.155, CI 95% 1.443-6.899), and playing with both plastic and cotton toys (p = 0.03, OR 2.796, CI 95% 1.072-7.295) were significant predictors of high BLLs. Maternal level of education correlated with blood lead concentrations (p = 0.048, OR 2.524, CI 95% 1.006-6.331)., Conclusions: A clinically significant number of cases of abdominal pain may have high BLLs. Specific attention should be paid to children presenting with abdominal pain, especially due to the detrimental effects of lead on their mental and motor development., (© 2021. The Author(s).)

- Abstract
Breast cancer, an unceasingly occurring neoplasm, is one of the major determinants of mortality in women. Several ineffective attempts have been pursued using with conventional therapies against breast cancer. Resistance to existing therapies and their respective debilitating adverse effects have led research toward a new era of cancer treatment using viruses. Virotherapy constitutes a developing treatment modality with multiple mechanisms of therapeutic activity in which the viruses can be directly oncolyticand can express transgenes or induce host immune response against tumor cells. Several different DNA- and RNA-containing viruses have been considered for virotherapy of breast cancer including adenovirus, herpes virus, vaccinia, reovirus, Newcastle Disease virus, measles virus and vesicular stomatitis virus. This review aims to summarize the viro-therapeutical agents against breast malignancies. Key Scientific Concepts of Review: In this review paper, we proposed a new strategy to virus's combinatorial treatments using several kinds of transgenes and drugs. These recombinant viruses have provided evidence of treatment efficacy against human breast cancer., Competing Interests: Authors declare no conflict of interests., (© 2021 The Authors.

- Abstract
Although Sanguisorba minor has been used as herbal medicine, no study has ever examined its potential toxicity. This study investigated acute and subacute toxicities of S. minor hydroalcoholic extract (SE). In the acute toxicity test, a single oral dose (300, 2,000, and 3,000 mg/kg) of SE was given to mice. The oral administration of SE (100, 200, and 400 mg/kg for 4 weeks) was performed to evaluate subacute toxicity. After the treatments, neurobehavioral, histopathology, hematological, and biochemical parameters were monitored. In vitro cytotoxicity was also assessed. Moreover, high-performance liquid chromatography fingerprint was done for the standardization of SE. The no-observed-adverse-effect level of SE was up to 2,000 mg/kg, and the LD
50 of the prepared extract was over 3,000 mg/kg. The rats exposed to the extract did not show any marked change in their body weight. The extract at used doses did not affect neuromuscular coordination. According to the hematological, biochemical, and histological examinations, no significant treatment-related adverse effect of the extract was observed, even at 400 mg/kg. Only 48 h exposure to 400 μg/mL of SE reduced the viability of PC12 cells. The findings revealed that this plant could be well-tolerated, regarded safe, and used as herbal medicine., (© 2021 Walter de Gruyter GmbH, Berlin/Boston.)- Published

- Abstract
Background: Granulomatosis with polyangiitis (GPA), also known as Wegener's granulomatosis, is an idiopathic systemic disease typically affecting the lungs, although other organs may also be involved., Case Presentation: A 28-year-old male was admitted to Baqiyatallah university hospital in Teheran (Iran) after a 3-week history of fever and productive cough. The patient gradually developed fatigue, arthralgia, hematuria, nausea, vomiting, dyspnea, hemoptysis, weight loss, oliguria and then anuria. Chest-X-ray (CXR) and computerized tomography scan revealed cavitating nodular opacities in the right lung lobe. Furthermore, plasma creatinine increased from 2.2 to 4 mg/dl in a few days. Histopathological examination of kidney biopsy revealed peri-glomerular and peri-vascular inflammation, degeneration and necrosis of the tubular epithelial lining, red blood cell casts, distorted glomerular structure, fibrin thrombi, segmental breaks of the glomerular basal membrane, disruption of Bowman's capsular membrane and crescent formation of the affected glomeruli. An abnormal CXR, an abnormal urinary sediment and a typical kidney histology were used as criteria to diagnose glomerulonefritis with poliangiitis (GPA). Bronchoalveolar lavage smear and PCR turned out positive for mycobacterium tuberculosis. After 3 months of treatment for (GPA) and tuberculosis the patient developed headache and seizure. Cerebral Magnetic Resonance Venography revealed cerebral venous thrombosis of the sinus transverse and sigmoid., Conclusions: Tuberculosis may coexist with GPA, as it occurred in our patient. Since a crescentic glomerulonephritis can progress to renal failure, clinicians should always be aware of potential multiple conditions when considering differential diagnoses., (© 2021.

- Abstract
Background: During the first wave of COVID-19, many Iranians were poisoned by ingesting hand sanitizers and/or alcoholic beverages to avoid viral infection. To assess whether the COVID-19 pandemic resulted in an increased prevalence of accidental hand sanitizer/alcoholic beverage exposure in children and adolescents, we compared pediatric hospitalization rates during COVID-19 and the previous year. For poisoning admissions during COVID-19, we also evaluated the cause by age and clinical outcomes., Methods: This retrospective data linkage study evaluated data from the Legal Medicine Organization (reporting mortalities) and hospitalization data from nine toxicology referral centers for alcohol-poisoned patients (age 0 to 18 years) for the study period (February 23 to June 22, 2020) and the pre-COVID-19 reference period (same dates in 2019)., Results: Hospitalization rates due to ethanol and methanol exposure were significantly higher in 2020 (n = 375) than 2019 (n = 202; OR [95% CI] 1.9 [1.6, 2.2], p < 0.001). During COVID-19, in patients ≤15 years, the odds of intoxication from hand sanitizers were significantly higher than from alcoholic beverages, while in 15- to 18-year-olds, alcoholic beverage exposure was 6.7 times more common (95% CI 2.8, 16.1, p < 0.001). Of 375 children/adolescents hospitalized for alcoholic beverage and hand sanitizer exposure in 2020, six did not survive. The odds of fatal outcome were seven times higher in 15- to 18-year-olds (OR (95% CI) 7.0 (2.4, 20.1); p < 0.001)., Conclusion: The Iranian methanol poisoning outbreak during the first wave of COVID-19 was associated with significantly increased hospitalization rates among children and adolescents-including at least six pediatric in-hospital deaths from poisoning. Public awareness needs to be raised of the risks associated with ingesting alcoholic hand sanitizers., (© 2021 Research Society on Alcoholism.)
