Published: August 2023

Chronic pancreatitis is a progressive inflammatory disease of the pancreas. Causes of gastrointestinal (GI) bleeding in chronic pancreatitis are bleeding into the pseudocyst, pseudoaneurysm of peripancreatic vessels, and thrombosis of portal vein and splenic vein. We are presenting a rare case presentation of recurrent GI bleed in chronic pancreatitis since childhood and its management. A seventeen-year-old female patient presented with recurrent attacks of upper abdominal pain, hematemesis, bleeding per rectum, and melena since 1 month of age. She was diagnosed with a case of chronic calcific pancreatitis with pseudoaneurysm of common hepatic artery, and portal vein thrombosis with splenomegaly at the age of 2 years. She underwent angioembolization of the common hepatic artery pseudoaneurysm at the age of 2 years. However, she continued to have recurrent episodes of upper GI bleeding which required multiple hospital admissions and blood transfusions in the past. Contrast-enhanced computed tomography of abdomen was suggestive of chronic calcific pancreatitis with status post coil embolization of common hepatic, gastroduodenal, and proper hepatic arteries. She underwent modified Frey’s procedure in view of recurrent symptoms. Currently, the patient is doing well after 18 months of follow-up, with no further episodes of GI bleed. Angioembolization or surgical ligation of pseudoaneurysm of involved vessels in chronic pancreatitis can control GI bleed. However, in cases where the source of bleeding is not localized by imaging/ endoscopy, drainage of pseudocyst or local resection of pancreatic tissue can reduce inflammation in and around the pancreas and prevent further GI bleed in chronic pancreatitis.

Published: August 2023

Background: Breast cancer (BC) is the second most common cancer in the world, and most frequent cancer among women. BC is a public health issue because of the highest rate of morbidity and mortality, so our study about the incidence of breast cancer among women in Al-Madinah Al-Munawara to answer many questions such as lifestyle, risk factor age, and the roles of the patients in awareness of the community.
Methods: It was a retrospective study that analyzed questionnaires collected from King Fahad Hospital and early diagnostic Taiba Cancer Screening centers from women patients with breast cancer after ethical consent in a specific time interval from January 2022 to March 2023 in Al-Madinah, Kingdom of Saudi Arabia.
Results: Among 111 women with breast cancer, 51.4% were diagnosed at the age 19 to 30 years, 16.2% were diagnosed at the age 31 to 40 years, 6.3% were diagnosed at the age 41 to 50 years, 20.7% were diagnosed at the age 51 to 60 years old, and 5.4% were diagnosed at an age over 60 years. 39.6% of women diagnosed with breast cancer have (1-3) children, 22.5% have (4-7) children, and 3.6% have more than (7) children. 56.2% of patients breastfeed their children, while 43.8% do not.
Conclusions: The incidence of breast cancer according to our study shows a high-risk factor in younger women, we suggest starting breast cancer screening from earlier age 19 years old and above. An increase in childbirth and lactation reduces the progress of breast cancer and prevents the disease, encouraging women with or without breast cancer for breastfeeding and childbirth. The experience and knowledge of patients with breast cancer about the disease make them active members in community awareness and urged other women to early screening, also the success story of recovering patients can be inspired for newly diagnose or relapse cases to complete their treatment by conducting educational meetings.

Authors: Tali Tavseef A. , Amin Fiza , Khan Nazir A. , Sofi Mushtaq A.
Published: August 2023

Craniopharyngioma is a rare type of benign (non-cancerous) brain tumor that primarily affects children and young adults. It arises from remnants of the Rathke's pouch, which is an embryonic structure that forms during the development of the pituitary gland. Craniopharyngiomas typically develop near the pituitary gland, in the area known as the sellar region. These tumors can cause various symptoms depending on their size and location, including hormonal imbalances, vision problems, headaches, and growth abnormalities. The management of craniopharyngioma involves a multidisciplinary approach, including surgery, radiation therapy, and hormone replacement therapy. Long-term outcomes can be influenced by the tumor's size, location, and the treatment modality used. Therefore, early recognition, accurate diagnosis, and appropriate treatment are crucial for optimizing the quality of life and long-term prognosis for individuals with craniopharyngioma. A detailed review of a number of craniopharyngioma cases is presented in this case series publication, with an emphasis on the clinical presentation, diagnostic methods, therapeutic options, and long-term results. This study's goal is to give doctors and researchers who work with patients who have this difficult malignancy useful information.

Published: August 2023

A diverse category of gliomas that mostly affect youngsters are known as brainstem gliomas (BGs). The diffuse intrinsic pontine glioma (DIPG), exophytic medullary glioma, and tectal glioma can be divided into categories based on architecture and clinical behaviour. The most frequent BG is DIPG. The median age at start is 6.5 years, and the median survival is less than a year. The fact that adults with DIPG live longer suggests that their tumours are less aggressive and have physiologically distinct origins than those in children. Patients may appear with one or more of the following symptoms: ataxia, long tract signs, or malfunction of the cranial nerves. The majority of the pons is occupied by an infiltrative lesion on magnetic resonance imaging, and contrast enhancement is typically not noticeable. Fractionated radiation is the norm in medicine.

Published: August 2023

The disposal of tailings generated from mining activities poses environmental challenges due to their low fertility and limited suitability for plant growth. This study aimed to investigate the potential of cow manure application in improving the organic-C content of tailings and enhancing the growth of water spinach (Ipomoea reptans). This experiment was laid out in a randomized block design with five treatments and five replications. The treatments involved the application of cow manure at different doses and control, which consisted of; (A) Control, (B) 150 g, (C) 300 g, (D) 450 g, (E) 600 g. The results revealed a significant increase in the organic-C content of tailings following the application of cow manure. The highest organic-C content of 7.47% was achieved with the application of 600 g of cow manure. The application of 150 g of cow manure resulted in the tallest plants with higher fresh and dry weights. The findings from this study underscore the importance of organic amendments in enhancing the organic-C content and promoting plant growth in low fertility growth medium. Further research on the long-term effects and optimization of cow manure application in tailing-based growth substrates is recommended to enhance soil fertility and maximize plant productivity.

Published: August 2023

Background: Breast cancer (BC) is the most common malignancy in women worldwide. The methylation status of MyoD1, a tumor suppressor gene, is enrolled in various cancers, i.e., BC. Various studies showed the impact of MyoD1 epigenetic dysregulation in BC. This study aimed to investigate the methylation status and expression level of MyoD1 in BC patients and its association with the expression of DNMT1.
Materials and Methods: This case-control study was conducted on 30 cases (pathology-confirmed ductal carcinoma) and 18 controls (fibroadenoma and fibrocystic masses), referred to Velayat Hospital, Qazvin, Iran. The expression of the MyoD1 and DNMT1 and the promoter methylation of the MyoD1 were evaluated in tissue blocks of BC patient masses using qRT-PCR and MS-PCR assays, respectively. SPSS 24.0 was used to analyze the data.
Results: The MyoD1 promoter is hypermethylated in BC patients compared to controls (p =0.001). The expression level of MyoD1 in BC patients was significantly reduced compared to controls (fold change =0.13, p =0.042). In addition, in BC patients, the reduced expression level of MyoD1 was significantly associated with methylation of the MyoD1 promoter (p =0.001). There is no significant difference between the expression level of DNMT1 in BC patients and controls (p =0.197). A significant association is found between the expression of DNMT1 and the methylation status of the MyoD1 promoter (p =0.038).
Discussion: The expression level of MyoD1 is affected by the methylation status of the promoter of this gene. Moreover, the expression level and methylation status of MyoD1 are correlated with clinical parameters.

Published: August 2023

Background: Chemotherapy with adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD regimen) cannot cure all patients with Hodgkin lymphoma. In this study, we evaluated the efficacy and adverse effect of a new regimen consist irinotecan, cisplatin, and dexamethasone (ICD) in relapsed and refractory Hodgkin lymphoma as the second to fifth line of treatment.
Materials and Methods: We performed a retrospective study in 26 relapsed or refractory patients with Hodgkin lymphoma receiving at least the first-line chemotherapy regimen (ABVD) and (ICD) as salvage therapy in Thaleghany Hospital from 2012 to 2018. This regimen consisted of irinotecan 65mg/m2 D1, D8, cisplatin 30mg/m2 D1, D8, and dexamethasone 40mg D1, 2, 8, and 9 was administered every 3 weeks for 6 cycles.  Treatment was discontinued in cases of disease progression or severe toxicity. Response to treatment was evaluated after two cycles. Patients with complete and partial remission were candidate high dose chemotherapy and autologous stem cell transplantation. Twenty-four patients were enrolled in the study. The mean age of 22 patients was 31.5 (19-67) years. Seven patients (29.1%) were in the first recurrence, and 17 (70.8%) were in the second or subsequent recurrence.
Results: According to this study, three patients (12.5%) had complete response, 13 (45%) had partial response, four (16.6%) had stable disease, and four (16.6%) had progressive disease. Nine patients (37.5%) received high-dose chemotherapy and autologous stem cell support after ICD regimen. None of the cycles of chemotherapy were delayed due to treatment-related adverse event. Overall survival after six months in all patients was 91%, and mortality rate was 8.3% at the end of the study.
Conclusion: The goal of salvage chemotherapy in relapsed or refractory Hodgkin Lymphoma is achieving CR or PR preparation patients for stabilization with BMT. Thus, we recommend ICD as one of the most effective protocols with overall response rate of 66% in this population.

Published: August 2023

Background: Transfusion support has an essential role in coronary artery bypass graft (CABG). The time-honored gold standard for CABG is the on-pump procedure (ONCAB); however, off-pump coronary artery bypass (OPCAB) is also a safe, cost-benefit procedure with fewer blood transfusion requirements. This study was performed to evaluate transfusion patterns in OPCAB due to the diversity of transfusion practices.
Materials and Methods: This retrospective study was performed to determine the transfusion rate and triggers in OPCAB patients. Medical files of all patients undergoing OPCAB surgery at Sanandaj Tohid Hospital in 2014 were reviewed. Patients’ demographics data, preoperative laboratory tests (PT, aPTT, Hb, Hct, Platelet count), underlying medical conditions, and their possible relation to further transfusions and the ward department in which the transfusion had taken place were extracted. SPSS 16 Chicago software, T-student Test, One Way Anova, and χ2 exam were applied for data analysis. P values ≤0.05was considered significant.
Results: Among 91 elective OPCAB patients: 28(30.8%) women and 63(69.2%) men with mean age of 64.80±9.02 years, 63(69.23%) received a blood product. Mean utilization of PRBC, FFP, Platelet, and Cryoprecipitate were 2.17±2.044, 2.46±2.86, 2.86±3.80 and 0.40±2.10 units, respectively. ICU revealed the highest consumption rate for all products.  Female sex (p<0.001), Hypertension (P=0.002), and low hemoglobin(P=0.004) were noted as predictive factors for transfusion. 
Conclusion: This study concluded that the transfusion rate in OPCAB is still very high in Iran (regarding a study in a countryside hospital) and that the highest utilization rate is seen in the ICU.

Authors: MUDABER Sebghatullah , BATUR Jenaidullah
Published: August 2023

This paper presents a comprehensive study of the differences in heavy metal adsorption on natural, modified, and synthetic zeolites. Heavy metal treatment and adsorption are critical issues in today's modern world, and despite advancements in technology, they remain a global challenge. Industrial effluents are a major source of heavy metal pollutants, which have a severe impact on human health and the environment. Therefore, removing heavy metals from contaminated water and wastewater is a necessity. Adsorption is the most commonly used method for removing heavy metals from the environment due to its cost-effectiveness, design, and performance. Among various adsorbents, zeolites are currently considered a suitable method due to their cost-effectiveness, simplicity, and the varying ion-exchange capacity of natural zeolites worldwide for cations such as ammonium and heavy metal ions. The findings of this research could provide useful information for developing efficient and cost-effective methods for the removal of heavy metals from water and wastewater, thus addressing a critical global issue. The outcomes of this research contribute to promoting a green and healthy environment.

Authors: TÜZÜN Elif
Published: August 2023

Modified composite electrodes have gained considerable interest in the detection of heavy metal ions due to their excellent sensitivity, selectivity, stability, and rapid response. Generally, these sensors consist of binder, conductive substance, and modifier. This study examined into the performance of a novel modified electrode that used a graphite–bleaching earth (BE-MCPE) composite performed while detecting trace amounts of Pb(II) using a differential pulse voltammetric technique (DPASV). In order to investigate the properties of BE-MCPE, we employed several analytical techniques, including SEM, SEM-EDX, FTIR, and XRD. These techniques were used to characterize the physical, chemical, and elemental properties of BE-MCPE, as well as its Pb(II) adsorption capacity, providing a comprehensive understanding of its composition and structure. The electrochemical results showed that the modified electrode demonstrated superior sensitivity and selectivity, in detecting Pb(II) ions, with a linear response range of 2.10-7 M to 10.10-7 M, limit of detection (LOD) of 4,89x10-8 mol.L-1, and limit of quantification (LOQ) of 1,63x10-7 mol.L-1. This novel modified electrode can achieve the sensitive detection of trace amounts of Pb(II) in a wide range of wastewater applications.
Analysis of lubricating oil degradation and its influence on brake specific fuel consumption of a light-duty compression-ignition engine running a durability cycle on a test stand
Authors: Sala Rafał , Węglarz Kamil , Suchecki Andrzej
Published: August 2023

The Euro 6 emission standard required compliance with legal exhaust emissions limits for newly registered vehicles and obligates light duty vehicle manufacturers to respect the 160,000 km durability requirements for in-service conformity. Although there is no legal limit set for fuel consumption, manufacturers are obligated to decrease the carbon footprint of vehicle fleets in order to obtain carbon neutral mobility beyond 2035.
The aim of this paper is to analyse the impact of various oils’ and viscosity grades’ degradation on the change in break specific fuel consumption (BSFC) measured over a standardized durability test cycle. Each oil candidate underwent 300 h of durability test running performed on a test bed, without any oil changes. The purpose of the laboratory test was to reproduce the worst-case operating conditions and degradation process of the long-life engine oil type that can be experienced during extreme real life driving of a vehicle.
In order to define the influence of the engine oil deterioration on the BSFC profile, the engine operation parameters were continually monitored throughout the test run. Additionally, chemical analysis of the oil was performed and the solid deposits formed on the turbocharger’s compressor side were evaluated.
The test results revealed differences up to 3.5% in the BSFC values between the oil candidates tested over the durability cycle. The observed BSFC increase was directly related to the decrease in engine efficiency and can cause higher fuel consumption of the engine, which in turn has an adverse effect on environmental protection goals.

Authors: Pan Jiajia , Meng Lijun , Li Rujun , Wang Zicheng , Yuan Wenjie , Li Yucheng , Chen Lin , Shen Qinhao , Liu Weili , Zhu Li
Published: August 2023

Background: Sepsis is one of the most common critical illnesses, with approximately 40% of patients experiencing complications of myocardial injury. Naringenin (Nar) is a natural flavonoid with benign biological effects, including anti-inflammatory, anti-bacterial, anti-oxidant, and anti-cancer effects. However, the specific effect of Nar on myocardial injury in sepsis has not yet been determined.
Methods: In vivo, the severity of cardiac histopathology and serum inflammatory factors were detected in the mouse model of lipopolysaccharide (LPS)-induced sepsis with/without naringenin treatment. Similarly, in vitro, a myocardial cell injury model was constructed by treating H9C2 cells with lipopolysaccharide (LPS), and the cell activity and apoptosis was detected by LDH and flow cytometry. Carry out transcriptome sequencing, bioinformatics analysis, Western blot and the molecular docking analysis to determine its molecular mechanism.
Results: Our study found that Nar treatment improved cardiac histopathological manifestations and reduced serum levels of inflammatory markers in a model of lipopolysaccharide (LPS)-induced sepsis. In addition, Nar attenuated LPS-induced cardiomyocyte apoptosis in vivo and in vitro. Mechanistically, Nar inhibited nuclear factor-kappa B translocation by activation of the phosphoinositide 3-kinase (PI3K)/protein kinase B(AKT) signaling pathway. Molecular docking results showed that Nar binds directly to the PI3K protein.
Conclusion: Nar has novel therapeutic potential for LPS-induced myocardial dysfunction, which provides a new target for the clinical prevention and treatment of septic cardiomyopathy.
Intention to Seek Mental Health Services During the 2022 Shanghai COVID-19 City-Wide Lockdown: Web-Based Cross-Sectional Study (Preprint)
Authors: Luo Lingzi , Li Gen , Tang Weiming , Wu Dan , Hall Brian
Published: August 2023

BACKGROUND

The implementation of COVID-19 lockdown measures had immediate and delayed psychological effects. From March 27, 2022, to June 1, 2022, the Shanghai government enforced a city-wide lockdown that affected 25 million residents. During this period, mental health services were predominantly provided through digital platforms. However, limited knowledge exists regarding the general population’s intention to use mental health services during this time.

OBJECTIVE

This study aimed to assess the intention of Shanghai residents to use mental health services during the 2022 Shanghai lockdown and identify factors associated with the intention to use mobile mental health services.

METHODS

An online survey was distributed from April 29 to June 1, 2022, using a purposive sampling approach across 16 districts in Shanghai. Eligible participants were adults over 18 years of age who were physically present in Shanghai during the lockdown. Multivariable logistic regression was used to estimate the associations between demographic factors, lockdown-related stressors and experiences, physical and mental health status, and study outcomes–mobile mental health service use intention (mobile applications and WeChat Mini Programs [Tencent Holdings Limited]).

RESULTS

The analytical sample comprised 3230 respondents, among whom 29.7% (weighted percentage; n=1030) screened positive for depression or anxiety based on the 9-item Patient Health Questionnaire or the 7-item Generalized Anxiety Disorder Scale. Less than one-fourth of the respondents (24.4%, n=914) expressed an intention to use any form of mental health services, with mobile mental health service being the most considered option (19.3%, n=728). Only 10.9% (n=440) used digital mental health services during the lockdown. Factors associated with increased odds of mobile mental health service use intention included being female, being employed, being a permanent resident, experiencing COVID-19–related stressors (such as loss of income, food insecurity, and potentially traumatic experiences), and having social and financial support. Individuals with moderate or severe anxiety, as well as those with comorbid anxiety and depression, demonstrated a higher intention to use mobile mental health services. However, individuals with depression alone did not exhibit a significantly higher intention compared with those without common mental disorders.

CONCLUSIONS

Despite a high prevalence of common mental disorders among Shanghai residents, less than one-fourth of the study respondents expressed an intention to use any form of mental health services during the lockdown. Mobile apps or WeChat Mini Programs were the most considered mental health service formats. The study provided insights for developing more person-centered mobile mental health services to meet the diverse needs of different populations.

Published: August 2023

Pastoralists and farmers’ activities guarantee food security while the pastoral systems have been the focus of conflicts in recent times in Nigeria. Much work has been done to explore the causes and effects of such conflicts from the farmers’ perspectives; hence this study approached it from the pastoralists’ viewpoint. The study examined the socio-cultural influence of interactions between pastoralists and farmers of the host communities in Nigeria. A three-stage random sampling procedure was used to select 121 pastoralists while data was collected using an interview schedule. Findings showed that 68.6% of the sample owned above 16 cattle and the annual income of 47.1% of the sampled pastoralists range from 100,000-500,000 Naira for over 16years. The factors triggering conflicts between pastoralists and their farmer hosts included: destruction of farmers' crops by herds, cattle rustling by thieves, sexual harassment involving their women, and harassment by the host community. This study also showed a relatively poor socio-cultural integration in intermarriage, understanding and speaking of host communities' language. Age, marital status, herd size, education level and income influenced the integration of pastoralists into host communities. The study concluded that there is a strong need for inter-marriages between pastoralists and farmers in furtherance of integration of the pastoralists with the socio-cultural values of the farmers. This can be achieved by engaging extension workers who will provide requisite enlightenment, education and training to the pastoralists. It thus becomes imperative for stakeholders to foster an enabling environment for improved social integration to assuage the rising conflicts. The study is novel as it documents the nexus between socio-cultural interaction and conflicts; with implication for capacity building, education and training on conflict resolution for livestock extension practitioners.

The study considers the features of the development of the primary roots of spring wheat seedlings after pre-sowing exposure to a UHF EMF under conditions of pre-moistening of seeds. The object of the experiment was the seeds of soft spring wheat (Triticum aestivum L.) varieties Novosibirskaya 31, Alyoshina, Trizo, Iren, Pamyati Aphrodite, and Altayskaya 70. In the experimental variants, the duration of the microwave EMF (0, 5, 10, 15 s) and the seed moisture (15, 20, 25, 30%) were combined. The influence of the UHF EMF on the intensity of the development of the primary roots of spring wheat seedlings was significant. For example, one of the varieties (Triso) shows a slight decrease in the intensity of growth processes during a fifteen-second treatment. The decrease in root mass was 18.18% (moisture content 15%) and 2.20 times (moisture content 20%) compared to the control. Wheat variety Iren had a decrease in root weight relative to the untreated variant by 2.59 times (at a moisture content of 15%) and 7.33 times (at a moisture content of 20%). The features of root growth at the initial stages of plant development were variety-specific and also depended on the modes of microwave processing. An unfavorable variant of microwave irradiation was a combination of the duration of exposure of 15 s and the preliminary humidity of the processed grain of 30%. The variant of EMF exposure for 5 s stimulated growth processes in germinating grains expressed in a relative increase in the number of roots and their wet weight compared to the control. The variant of exposure to an EMF for 5 s stimulates growth processes in germinating grains, which is expressed in a relative increase in the number of roots compared to the control. This difference is 13.47% for the Novosibirskaya 31 variety, for the Trizo variety – 14.99%, Iren – 12.44%, Pamyati Aphrodite – 8.97%, and Alyoshina – 13.93% on average. According to the totality of the studied indicators, two varieties of spring wheat were distinguished: the variety of Pamyati Aphrodite as the most stable and the variety Alyoshina as the most plastic. The results obtained can be used in practical plant growing to increase the adaptive capacity of plants and, consequently, increase productivity. A well-developed root system will allow wheat to withstand adverse weather conditions and form a higher grain productivity.

A total of 150 samples were collected from seven layers poultry farms IN Wasit Province of Iraq. Fifty (50) from layers poultry and hundred (100) from farm premises including poultry feed, surfaces associated with feed container and water drinkers indicating isolation of 60 (40%) mold and yeast based on morphological characteristics and diagnosed to species by using sequencing of the internal transcribed spacer region. Aspergillus versicolor recorded higher isolation rate 20/60 (33.3%), followed by Candida albicans 16/60 (26.6%), Aspergillus wlwitschiae 12/60 (20%), Diutina catenulata 10/60 (16.6%), and the lowest percentage was observed for Lichtheimia ramose 2/60 (3.3%). The analyses of Mycotoxins in poultry feed conducted by Enzyme Linked Immunosorbent Assay (ELISA), revealed aflatoxins B1 (AFB1) in all feed samples (70) with total range (6.945 ppb), and for each: soybean (8.060 ppb), corn (3.287 ppb) and wheat (3.287 ppb). While 60 (85%) out of 70 sample were contaminated with ochratoxin in feed samples with total range (2.658 ppb), for soybean, corn and wheat as (1.122 ppb), (2.596 ppb) and (1.068 ppb) respectively (permissible ratios <20 ppb). Also about 14 (57%) out of 70 samples were contaminated with T2 toxin with total feed range (33.629%) as (113.321 ppb) for corn, (99.817 ppb) for soybean and (64.486 ppb) for wheat samples (permissible ratios <100). This study indicates the importance of continuous mycological evaluation of poultry feed production, hen’s fungal infections and Mycotoxins contamination may directly threaten the industry and harm the consumers at the same time.

Authors: Shiyekar Sandeep , Patil Apurva
Published: August 2023

Abstract: This paper presents a numerical method using ANSYS to estimate the buckling loads of composite plates. Our approach employs an element based on FSDT that considers out-of-plane shear deformation. We used an Eight node SHELL281 element that is well-suited for analyzing plate and shell structures. The ANSYS results for buckling loads of isotropic and orthotropic layered laminates are in good agreement with other theories from the literature. In this study, we investigated uniaxial and biaxial buckling of the plates and also considered the degree of orthotropy to study its impact on the plates' buckling.
