Abstract
Fibrosis refers to excessive build-up of scar tissue and extracellular matrix components in different organs. In recent years, it has been revealed that different cytokines and chemokines, especially Transforming growth factor beta (TGF-β) is involved in the pathogenesis of fibrosis. It has been shown that TGF-β is upregulated in fibrotic tissues, and contributes to fibrosis by mediating pathways that are related to matrix preservation and fibroblasts differentiation. There is no doubt that antioxidants protect against different inflammatory conditions by reversing the effects of nitrogen, oxygen and sulfur-based reactive elements. Oxidative stress has a direct impact on chronic inflammation, and as results, prolonged inflammation ultimately results in fibrosis. Different types of antioxidants, in the forms of vitamins, natural compounds or synthetic ones, have been proven to be beneficial in the protection against fibrotic conditions both in vitro and in vivo. In this study, we reviewed the role of different compounds with antioxidant activity in induction or inhibition of TGF-β/SMAD signalling pathway, with regard to different fibrotic conditions such as gastro-intestinal fibrosis, cardiac fibrosis, pulmonary fibrosis, skin fibrosis, renal fibrosis and also some rare cases of fibrosis, both in animal models and cell lines.

Abstract
Brain metastases in breast cancer (BC) patients are often associated with a poor prognosis. Recent studies have uncovered the critical roles of miRNAs in the initiation and progression of BC brain metastasis, highlighting the disease's underlying molecular pathways. miRNA-181c, miRNA-10b, and miRNA-21, for example, are all overexpressed in BC patients. It has been shown that these three miRNAs help tumors grow and metastasize by targeting genes that control how cells work. On the other hand, miRNA-26b5p, miRNA-7, and miRNA-1013p are all downregulated in BC brain metastasis patients. They act as tumor suppressors by controlling the expression of genes related to cell adhesion, angiogenesis, and invasion. Therapeutic miRNA targeting has considerable promise in treating BC brain metastases. Several strategies have been proposed to modulate miRNA expression, including miRNA-Mimics, antagomirs, and small molecule inhibitors of miRNA biogenesis. This review discusses the aberrant expression of miRNAs and metastatic pathways that lead to the spread of BC cells to the brain. It also explores miRNA therapeutic target molecular mechanisms and BC brain metastasis challenges with advanced strategies. The targeting of certain miRNAs opens a new door for the development of novel therapeutic approaches for this devastating disease.

Abstract
Breast cancer is a genetically heterogeneous disorder associated with dysregulation of several genes. Peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-dependent transcription factor that is expressed by many tumoral cells such as transformed breast cancer cells. We investigated expressions of nine PPARγ-related lncRNAs, namely KCNIP2-AS1, TRHDE-AS1, FAM13A-AS1, ALDH1A1-AS2, SH3BP5-AS1, HID1-AS1, LINC01140, LIPE-AS1 and ABCA9-AS1 in paired breast cancer samples and non-tumoral tissues. Expression assays showed lower expression levels of TRHDE-AS1, ALDH1L1-AS2, KCNIP2-AS1, ABCA9-AS1, LIPE-AS1 and LINC01140 in tumoral compared with non-tumoral samples. The mentioned genes could differentiate between breast tumors and non-tumoral samples with AUC values ranging from 0.77 to 0.62 for LINC01140 and LIPE-AS1, respectively. The highest specificity and sensitivity values were reported for KCNIP2-AS1 and LINC01140, respectively. Significant correlations were reported between all pairs of genes in both tumoral and non-tumoral tissues. The most robust ones were between ABCA9-AS1 and KCNIP2-AS1 (correlation coefficient=0.85) in non-tumoral tissues and between LIPE-AS1 and TRHDE-AS1 (correlation coefficient=0.83) in tumoral tissues. There was a significant negative association between expression levels of KCNIP2-AS1 gene in tumor tissues and different histological grades. Besides, there was a significant negative association between expression levels of FAM13A-AS1, KCNIP2-AS1and LIPE-AS1 genes in tumor tissues and different mitotic rates. Taken together, PPARγ-related lncRNAs might be regarded as potential contributors to the pathogenesis of breast cancer.

Abstract
Small nucleolar RNA host gene 12 (SNHG12) is a long non-coding RNA (lncRNA) that contributes in a variety of human pathologies. This lncRNAs acts as molecular sponge for various miRNAs, namely miR-200c-5p, miR-129-5p, miR-30a-3p, miR-195, miR-133b, miR-199a/b-5p, miR-320b, miR-16, miR-15a, miR-218-5p, miR-320 and a number of other miRNAs. Through this mechanism, SNHG12 can affect activity of HIF-1α, Wnt/β-catenin, VEGF, PI3K/AKT/mTOR, PTEN, NF-κB and ERK-1/2 signaling. SNHG12 can affect pathogenesis of several disorders, including those arising from genitourinary, gastrointestinal, pulmonary, central nervous and cardiovascular systems. These effects have been best characterized in the context of cancer where it can be used as a possible diagnostic and prognostic marker. In order to summarize the role of this lncRNA in human disorders, particularly cancer and highlight its potential application in biomedical studies, we designed the current review. We also emphasized on its diagnostic and prognostic roles.

Abstract
The cytokine known as transforming growth factor (TGF) is essential for cell development, differentiation, and apoptosis in BC. TGF-β dysregulation can either promote or inhibit tumor development, and it is a key signaling pathway in BC spread. A recently identified family of ncRNAs known as lncRNAs has received a great deal of effort and is an important regulator of many cellular processes, including transcription of genes, chromatin remodeling, progression of the cell cycle, and posttranscriptional processing. Furthermore, both TGF-β signaling and lncRNAs serve as important early-stage biomarkers for BC diagnosis and prognosis and also play a significant role in BC drug resistance. According to recent studies, lncRNAs can regulate TGF-β by modulating its cofactors in BC. However, the particular functions of lncRNAs and the TGF-β pathway in controlling BC progression are not well understood yet. This review explores the lncRNAs' functional properties in BC as tumor suppressors or oncogenes in the regulation of genes, with a focus on dysregulated TGF-β signaling. Further, we emphasize the functional roles of lncRNAs and TGF-β pathway in the progression of BC to discover new treatment strategies and better comprehend the fundamental cellular pathways.

Abstract
INTRODUCTION AND IMPORTANCE Abdominal wall hernia is a protrusion of abdominal contents through an acquired or congenital weakness or wall defect. A ventral hernia, including an appendix, is a rare condition. The appendix in the hernial sac is already known as inguinal and femoral hernia and has been named Amyand hernia and De Garengeot hernia, respectively. CASE PRESENTATION We have presented a 74-year-old woman with complaints of point tenderness in the right lower abdomen and para-umbilical and a palpable non-reducible mass over the para-umbilicus with some erythema on the skin, which started two days ago. With the help of imaging, diagnosis of abdominal wall hernia was made, with the appendix as the possible content, as there was evidence of an inflamed appendix lumen incarcerated through the abdominal wall. CLINICAL DISCUSSION We have provided a detailed review of recent articles. Our comprehensive discussion includes an exploration of the typical manifestations, the significance of imaging in accurate diagnosis, and the appropriate measures to facilitate optimal surgical preparation. The treatment for ventral hernia typically involves appendectomy and abdominal wall hernia repair, with the specific approach depending on the severity of inflammation. CONCLUSION Although abdominal wall hernia containing appendicitis is extremely rare, its clinical manifestations are hernia and acute appendicitis, the most common diseases in general surgery. Imaging may be helpful in diagnosis. According to our study, diagnostic laparoscopy could be used in case of clinical suspicion of abdominal wall hernia containing an appendix, although more studies are needed.

Abstract
INTRODUCTION AND IMPORTANCE Ventral gallbladder hernia is a rare condition mostly related to past acquired abdominal wall defects, but spontaneous ones are scarce. It happens more in elderly patients. Etiology and causes are still unspecified, but the most related known causes of spontaneous gallbladder herniation are carcinoma, biliary tracked occlusion or abdominal wall weakness in elderly patients, respectively. CASE PRESENTATION We have presented a complicated 90-year-old woman with a bulged and warm area at the right upper abdomen with tenderness and positive rebound tenderness. In help with imaging, we found a ventral gallbladder hernia perforated in the subcutaneous layer. Then cholecystectomy and herniation site repair was performed. CLINICAL DISCUSSION We have explained this infrequent scenario and reviewed recent similar papers to find further relevant information. The common presentations, probable causes, the role of imaging in diagnosis and the management are discussed for the best surgical planning. CONCLUSION The spontaneous ventral herniation of the gallbladder is an exceedingly uncommon occurrence. The diagnosis of this condition heavily relies on imaging, with computed tomography (CT) scan utilizing both intravenous and oral contrast being the optimal modality. Management of this condition can be accomplished via both laparoscopic and laparotomy approaches. It is our recommendation to perform cholecystectomy and hernia repair simultaneously and expeditiously in all cases. We advise against conservative management strategies.

Abstract
BACKGROUND Breast cancer recurrence is a traumatic event for patients, and its treatment depends on the patient's ability to accept the circumstances. OBJECTIVE The aim of this study was to explore how patients experience breast cancer recurrence and go through a process of negotiating acceptance. METHODS This study explored the experiences of 16 patients with breast cancer recurrence regarding the acceptance of recurrence in a hospital in Tehran, Iran. Purposive sampling with maximum diversity was used. Data were collected through semistructured telephone interviews from November 2020 to November 2021 and analyzed using the qualitative content analysis. RESULTS Four themes emerged that described the process of accepting cancer recurrence: (1) response to recurrence (emotional reactions and loss of trust); (2) psychological preparedness (confirmation of medical diagnosis and acceptance of fate); (3) mobilizing supports (using spiritual capacities, utilizing supportive resources, and seeking relationships to promote knowledge); and (4) return to the path of treatment (rebuilding trust and continuation of treatment). CONCLUSIONS The acceptance of breast cancer recurrence is a process that begins with emotional reactions and ends with returning to the treatment path. The patient's psychological preparation, support systems, behavior of healthcare providers, and rebuilding trust are the determining factors in acceptance of recurrence. IMPLICATIONS FOR PRACTICE Nurses can compensate for the failures created in the primary treatment of breast cancer by spending time with patients and paying attention to their concerns, providing effective education, strengthening communication between patients with similar conditions and using the spiritual capacities of patients, and mobilizing the support of family and relatives.

Abstract
INTRODUCTION High false-negative results have been reported for fine-needle aspiration (FNA) cytology in thyroid nodules. Fine-needle capillary (FNC) cytology is an alternative technique that prevents aspiration, reducing tissue damage. This study aimed to compare FNA and FNC in assessing thyroid nodules and in terms of their predictive role in the appropriate diagnosis of malignancy. METHODS This is a comparative prospective study conducted on 486 patients. FNA was performed in 235 patients during 2016 and 2017 and FNC in 251 patients during 2018 and 2019. The quality of cytological specimens was compared and then correlated with the final histopathological findings of 39 patients who underwent thyroidectomy. RESULTS Both groups were statistically similar regarding age and sex distribution. The FNA technique yielded significantly higher adequate specimens compared with FNC (p<0.001). Abundant blood in the background was found more frequently in the FNA technique (p<0.001). The sensitivity and specificity of FNA for malignancy diagnosis were both 100%, compared with 83.3% and 57.7% for FNC, respectively. CONCLUSIONS The two methods, FNA and FNC, did not differ in terms of overall quality. FNA was superior regarding consistency with the histopathological results and the ability to diagnose malignancy.

Abstract
Cholangiocarcinoma is a rare tumor but a challenging cancer in terms of pathological changes, clinical manifestations and therapeutic options. Recent studies have provided evidence for participation of non-coding RNAs in the carcinogenic process of cholangiocarcinoma. We demonstrate the role of long non-coding RNAs, microRNAs and circular RNAs in the pathogenesis of cholangiocarcinoma and highlight their significant position as therapeutic targets and biomarkers for this type of cancer. We also list a number of molecular axes comprising these non-coding RNAs that represent potential targets for therapeutic options in cholangiocarcinoma, based on their significant roles in the regulation of cell proliferation, differentiation and apoptosis of these cells.

Abstract
NR2F1-AS1 is a natural antisense transcript with prominent roles in the carcinogenesis. It acts as an oncogene in almost all types of cancers except for cervical and colorectal cancers. It can act as a molecular sponge for miR-17, miR-371a-3p, miR-363, miR-29a-3p, miR-493-5p, miR-190a, miR-140, miR-642a, miR-363, miR-493-5p, miR-483-3p, miR-485-5p, miR-146a-5p, miR-877-5p, miR-338-3 P and miR-423-5p to influence expression of several cancer-related genes. Thus, the sponging role of NR2F1-AS1 is the most appreciated route of its contribution in the carcinogenesis. In addition, NR2F1-AS1 affects activity of IGF-1/IGF-1R/ERK, PI3K/AKT/GSK-3β and Hedgehog pathways. The current narrative review aims at summarization of the results of studies that highlighted the role of NR2F1-AS1 in the carcinogenesis.

Abstract
MicroRNAs (miRNAs) are small-sized transcripts with about 22 nucleotide length. They have been shown to influence almost every aspect of cellular functions through regulation of expression of target genes. miR-1908 is a miRNA with diverse roles in human disorders. This miRNA is encoded by MIR1908 gene on chr11:61,815,161-61,815,240, minus strand. Expression assays have confirmed dysregulation of miR-1908 in cancer-derived cell lines in addition to biological samples obtained from patients affected with cancer. In most assessed cell lines, miR-1908 has an oncogenic role. However, this miRNA has been shown to act as a tumor suppressor in chordoma, lung cancer and ovarian cancer. In addition, several lines of evidence have shown involvement of this miRNA in the pathoetiology of bipolar disorder, myocardial infarction, obesity, renal fibrosis, rheumatoid arthritis and scar formation. In the current review, we elucidate the results of diverse studies which evaluated participation of miR-1908 in these conditions.

Abstract
Sonic Hedgehog (Shh) signaling cascade is one of the complex signaling pathways that control the accurately organized developmental processes in multicellular organisms. This pathway has fundamental roles in the tumor formation and induction of resistance to conventional therapies. Numerous non-coding RNAs (ncRNAs) have been found to interact with Shh pathway to induce several pathogenic processes, including malignant and non-malignant disorders. Many of the Shh-interacting ncRNAs are oncogenes whose expressions have been increased in diverse malignancies. A number of Shh-targeting miRNAs such as miR-26a, miR-1471, miR-129-5p, miR-361-3p, miR-26b-5p and miR-361-3p have been found to be down-regulated in tumor tissues. In addition to malignant conditions, Shh-interacting ncRNAs can affect tissue regeneration and development of neurodegenerative disorders. XIST, LOC101930370, lncRNA-Hh, circBCBM1, SNHG6, LINC‐PINT, TUG1 and LINC01426 are among long non-coding RNAs/circular RNAs that interact with Shh pathway. Moreover, miR-424, miR-26a, miR-1471, miR-125a, miR-210, miR-130a-5p, miR-199b, miR-155, let-7, miR-30c, miR-326, miR-26b-5p, miR-9, miR-132, miR-146a and miR-425-5p are among Shh-interacting miRNAs. The current review summarizes the interactions between ncRNAs and Shh in these contexts.

Abstract
ING genes belong to family of tumor suppressor genes with regulatory functions on cell proliferation, apoptosis, and cellular senescence. These include a family of proteins with 5 members (ING1-5), which are downregulated in human malignancies and/or affected by pathogenic mutations. ING proteins are highly evolutionarily conserved proteins containing several domains through which bind to chromatin structures by exerting their effects as readers of histone modification marks, and also binding to proteins like p53 involved in biological processes such as cell cycle regulation. Further, they are known as subunits of histone acetylation as well as deacetylation complexes and so exert their regulatory roles through epigenetic mechanisms. Playing role in restriction of proliferative but also invasive potentials of normal cells, INGs are particularly involved in cancer development and progression. However, additional studies and experimental confirmation are required for these models. This paper highlights the potential impact that INGs may have on the development of human cancer and explores what new information has recently arise on the functions of ING genes.

Abstract
Hypertension is a multifactorial condition in which several genetic and environmental elements contribute. Recent investigations have revealed contribution of non-coding region of the transcriptome in this trait. CDKN2B-AS1, AK098656, MEG3, H19, PAXIP1-AS1, TUG1, GAS5, CASC2 and CPS1-IT are among long non-coding RNAs participating in the pathophysiology of hypertension. Several miRNAs have also been found to be implicated in this disorder. miR-296, miR-637, miR-296, miR-637, hsa-miR-361-5p, miR-122-5p, miR-199a-3p, miR-208a-3p, miR-423-5p, miR-223-5p and miR-140-5p are among dysregulated miRNAs in this condition whose application as diagnostic biomarkers for hypertension has been evaluated. Finally, hsa-circ-0005870, hsa_circ_0037911 and hsa_circ_0014243 are examples of dysregulated circular RNAs in hypertensive patients. In the current review, we describe the role of these non-coding RNAs in the pathophysiology of hypertension.

Abstract
Ovarian cancer is a female malignancy with high fatality-to-case ratio, which is due to late detection of cancer. Understanding the molecular mechanisms participating in these processes would facilitate design of therapeutic modalities and identification of novel tumor markers. Recent investigations have shown contribution of circular RNAs (circRNAs) in the evolution of ovarian cancer. These transcripts are produced through a back-splicing mechanism. The enclosed configuration of circRNAs protects them from degradation and potentiates them as biomarkers. Several circRNAs such as circMUC16, circRNA_MYLK, circRNA-UBAP2, circWHSC1, hsa_circ_0013958, circFGFR3, hsa_circRNA_102958 and circ_0072995 have been found to be up-regulated in this cancer, acting as oncogenes. On the other hand, circ-ITCH, circPLEKHM3, circ_100395, circ_0078607, circATRNL1, circHIPK3, circRHOBTB3, circEXOC6B, circ9119 and CDR1as are among down-regulated circRNAs in ovarian cancer. Expression levels of circCELSR1, circ_CELSR1, circATL2, circNRIP1, circTNPO3 and hsa_circ_0000714 have been shown to affect resistance of ovarian cancer cells to chemotherapy. Moreover, circ_100395, circFGFR3, circ_0000554, circCELSR1, circ-PTK2, circLNPEP, circ-CSPP1, circ_0000745, circ_100395 and circPLEKHM3 have been shown to regulate epithelial-mesenchymal transition and metastatic ability of ovarian cancer cells. In the current review, we explain the roles of circRNAs in the evolution and progression of ovarian cancer.

Abstract
TP53 encodes a major tumor suppressor protein which blocks carcinogenesis process in a variety of tissues including breast tissue. Expression and function of this gene is regulated by a number of long non-coding RNAs (lncRNAs) among them are PANDA, MEG3 and CASC2. We measured expression of TP53 and these transcripts in a cohort of Iranian breast cancer patients. Expression levels of TP53, MEG3, CASC2 and PANDA were significantly lower in tumoral samples compared with non-tumoral samples (Posterior mean differences = -4.26, -1.66, -5.98 and -3.13, respectively; P values < 0.0001). Expression of CASC2 was higher in Her2 1+ cases compared with Her2 negative cases (Beta = 1.85, P value = 0.037). Expression levels of MEG3 and TP53 were lower in grade 2 samples compared with grade 1 (Beta = -1.86, P value = 0.006 and Beta = -2.24, P value = 0.003, respectively). There was no other significant association between expression of genes and clinical variables. CASC2 had the best performance among these genes with area under curve value of 0.78 and sensitivity and specificity values of 56.33% and 88.73%, respectively (P value < 0.0001). The current investigation supports the role of TP53-related lncRNAs in the pathogenesis of breast cancer.

Abstract
The pandemic caused by severe acute respiratory syndrome coronavirus 2 and the related disorder i.e. “coronavirus disease 2019” (COVID-19) has encouraged researchers to unravel the molecular mechanism of disease severity. Several lines of evidence support the impact of “cytokine storm” in the pathogenesis of severe forms of the disorder. We aimed to assess expression levels of nine cytokine coding genes in COVID-19 patients admitted in a hospital. We collected clinical data of patients from their medical reports. Then, we assessed expression of genes using real-time PCR. Expression levels of IFN-G, IL-2, IL-4, IL-6, IL-17, TGF-B, IL-8, and IL-1B were significantly higher in COVID-19 patients compared with healthy controls and in both female and male patients compared with sex-matched controls. However, expression level of TNF-A was not different between COVID-19 patients and healthy controls. Expression of none of these cytokines was different between ICU-admitted patients and other patients except for IL-6 whose expression was lower in the former group compared with the latter (ratio of means = 0.33, P value = 4.82E-02). Then, we assessed diagnostic power of cytokine coding genes in differentiating between COVID-19 patients and controls. The area under curve (AUC) values ranged from 0.94 for IFN-G to 1.0 for IL-2 and IL-1B. After combining the transcript levels of all cytokines, AUC, sensitivity, and specificity values reached 100%, 100%, and 99%, respectively. For differentiation between ICU-admitted patients and other patients, IL-4 with AUC value of 0.68 had the best diagnostic power among cytokine coding genes. Expression of none of cytokine coding genes was correlated with the available clinical/demographic data including age, gender, ICU admission, or erythrocyte sedimentation rate (ESR)/C-reactive protein (CRP) levels. This study provides further evidence for contribution of “cytokine storm” in the pathobiology of moderate/severe forms of COVID-19.

Abstract
Introduction and importance Tubo-ovarian abscesses (TOA) is presented with multiple clinical manifestations including gastrointestinal findings. Case presentation Herein, we present a case of complicated diverticulitis that was misdiagnosed as TOA, owing to overlapping genital involvement. Clinical discussion Imaging could be misleading in these patients as a result of severe inflammation of intestines and surrounding organs. Conclusion Patients who do not respond to antibiotic treatment should be suspected of other gastrointestinal pathologies such as diverticulitis and should be evaluated accordingly. Concomitant presentation of diverticulitis and Tubo-ovarian abscesses (TOA) has been rarely reported. Diverticulitis can also be complicated, indicated by the involvement of other organs such as ovaries and fallopian tube. In such cases, pathological evaluation, following the surgical intervention can indicate the exact disease.

Abstract
The modified Becke-Johnson exchange (mBJ) potential plus the generalized gradient approximation (GGA) correlation are used for the calculation of the optoelectronic properties of the C7H10N2 pyridine and C7H10N2S pyrrole. Electronic band gaps of C7H10N2 pyridine and C7H10N2S pyrrole have been determined to be 4.65 eV and 3.41 eV by band structure spectra, respectively. According to the Penn model, there is an inverse relationship between the band gap value and static dielectric constant along the x-direction. The density of states spectra shows that the p state of S atoms plays a key role in the optical spectra. In the refractive index spectra, the nature of materials changes from linear to nonlinear with superluminal nature in a narrow energy range of 3.9-4.7 eV for C7H10N2S and 5-7.7 eV for C7H10N2. Cauchy parameters are calculated and predicted values are extended in the UV (ultraviolet) and visible regions. Obtained plasmon energies are in close agreement with suitable optical materials such as α-Al2O3 making the material more effective to use in new optical devices.

Abstract
Breast cancer is a common neoplasm among women. This type of cancer is among malignancies in which role of long non-coding RNAs (lncRNAs) has been extensively explored. Some recently recognized lncRNAs have been less investigated in this neoplastic condition. LncRNAs that regulate tumor immunity are among those contributing in the pathogenesis of cancer. In the present expression assay, we compared expressions of nine immune-related lncRNAs namely lnc-MICAL3-2 (AC016027.1), lnc-DDX31 (AL445645.1), LINC01063, LINC02381, ENST0000615051 (AC083809.1), AC009237.14 (lnc-TRIM43B-1), ENST0000603791, LINC1234 and AC008760.1 between breast cancer samples and their paired non-cancerous samples. Expression levels of lnc-MICAL3-2, lnc-DDX31, LINC01063, LINC02381, ENST0000615051 and lnc-TRIM43B-1 were significantly decreased in breast cancer samples compared with paired control tissues (Posterior mean difference= -2.774, -2.012, -2.012, -2.015, -0.884 and -2.872; P values= 0.019, 0.0001, 0.0001, 0.0001, 0.032 and 0.0001, respectively). Expression levels of these lncRNAs have been associated with a number of clinical characteristics of breast cancer patients. Lnc-TRIM43B-1 had the highest performance in distinguishing between tumoral and non-tumoral tissues (AUC=0.82, Sensitivity=76%, Specificity=73.24%). As these lncRNAs could differentiate tumor samples from control samples, they might be regarded as putative tissue markers for breast cancer.

Abstract
Coronavirus disease 2019 (COVID-19) has caused a global pandemic in early 2020. This infectious disorder has a heterogeneous course ranging from asymptomatic disorder to a critical situation needing intensive cares. In the current study, we present a report of affected patients admitted in a single hospital in Iran. Eighty-two hospitalized patients with COVID-19 were assessed. Demographic, clinical, and paraclinical parameters were gathered and statistically analyzed. The median age (IQR) of the patients was 57.32 (45.75, 70) years. At primary evaluation, fever was present in 45.12% of the affected individuals. The most common clinical symptoms were dyspnea (81.71%) and cough (65.85%). Totally, 12 (14.63%) and 14 (17.07%) of patients had low and high WBC counts, respectively. Lymphopenia was detected in 36 (43.9%) of patients, while 6 (7.32%) of patients had lymphocytosis. High levels of Il-6 were detected in 4 (4.88%) of patients. CRP levels were elevated in 69 (84.1%) of patients. The median (IQR) of hospitalization was 7 (5, 9) days. Totally, 26 patients (31%) were hospitalized in ICU. All patients were discharged with good health conditions except for one patient who died. The current study shows the heterogeneous clinical manifestations and paraclinical parameters of COVID-19 patients.

Abstract
Background Breast cancer (BC) is the most frequent cause of cancer death in women. The thoracic pectoral nerve (PECS) block has been described as the gold standard analgesic modality for BC surgery. It has been previously reported that PECS is associated with decreased BC recurrence post-mastectomy. Although several anesthetic drugs and techniques are used in surgical oncology, their effects on the behavior of cancer cells are yet to be known and the key question of whether the anesthetic technique affects cancer outcome remains unresolved. Objectives Since anesthetic drugs and techniques and post-operative pain may affect BC recurrence, this study aimed to determine whether the anesthetic choice and technique, PECS II block, affects in vitro apoptosis of the MDA-MB-231 BC cell line. Methods Twenty-two female BC patients, 20 to 75-years-old, with the same pathologic grades were included in this study. The patients were randomly divided into two groups. The first group received propofol general anesthesia (PGA) associated with PECS and the second group received standard PGA. Blood was sampled pre and post-operation from all patients. The sera were isolated and then exposed to the MDA-MB-231 human BC cell line. The mean percentage of apoptosis indices was analyzed by flow cytometry using Annexin V-fluorescein isothiocyanate 24 hours after treatment with patients' sera. Results A significant decrease was seen in the mean viability percentage of BC cell line in the PECS group, besides a significant increase in the mean percentage of necrosis and late apoptosis indices compared to the control group after exposure to sera collected from patients post-operation. Intra-group analysis of the control group showed that the exposure of the tumoral cell to post-operation sera resulted in a significant increase in the mean percentage of necrosis and late apoptosis index compared to pre-operation sera exposure. In the PECS group, the exposure of the tumoral cell to post-operation sera resulted in a significant increase in the mean percentage of cell viability and late apoptosis index compared to pre-operation sera exposure. Conclusions In conclusion, anesthesia and BC surgery may induce apoptosis indices in the MDA-MB-231 human BC cell line. We also found that sera collected from PECS II block patients with BC could induce more apoptosis in the MDA-MB-231 cell line compared to collected sera from systemic analgesia alone after BC surgery.

Abstract
INTRODUCTION Hydatid Disease (HD), or hydatidosis or echinococcosis, is an endemic infection and a major public health concern in the Mediterranean region. At times it involves the primary soft tissues, such as in the breast and muscle, though this is quite uncommon even in endemic areas. PRESENTATION OF CASES A. A 31 year-old woman complained of a gradual progressive, painless lump in the left axillary tail of spence for two years. Examination revealed a firm lump measuring 5cm × 5cm, non-mobile, in the left axillary tail of Spence. B. A 32 year-old woman presented with mild and continuous pain in lateral aspect of left thigh. On examination, there was a round, non-tender, non-mobile mass in the lateral aspect of her left thigh. Preoperative imaging studies in both patients revealed evidence of HD. Both of the patients underwent surgery and received Albendazole twice per day for 10 days, before and three months after surgery. DISCUSSION The disease can be diagnosed by serological and radiological modalities, both of which are not definitive. Ultrasonography should be the first diagnostic modality of soft tissue HD, however, MRI can be used to understand clearly the surgical involvements of structures. The standard treatment of soft tissue HD is surgery using pericystectomy techniques, as well as anthelmintic therapy. CONCLUSION HD should be suggestive in soft tissues if mass is slowly developing and presenting with local extension, particularly in endemic countries. Excision of HD using pericystectomy technique is the first choice of intervention for HD of soft tissues.

Abstract
BACKGROUND To assess the effect of preoperative smoking cessation on postoperative complications in patients undergoing herniorrhaphy. MATERIALS AND METHODS This prospective study was conducted on 163 consecutive patients, undergoing herniorrhaphy. Demographic characteristics and postoperative complications were compared between smokers (group A), patients who reduced smoking by 50% (group B), and patients who completely quit smoking (group C). RESULTS The mean age of the patients was 42.9 (SD=10.3) years. Group A (n=77), group B (n=27), and group C (n=59) were not significantly different in terms of age, body mass index (BMI), medical history, laboratory data, smoking habit, type of hernia, type of anesthesia, the American Society of Anesthesiologists (ASA) class, repair method, surgery approach, and duration surgery (P>0.05 for all). However, significant differences were observed between group B and group A, group C and group A, and group C and group B regarding postoperative complications, such as wound healing complications and length of hospital stay (LOS) (P<0.05 for all). CONCLUSION Decreased preoperative smoking is associated with the reduced risk of respiratory, cardiovascular, and wound healing complications and decreased LOS in patients undergoing herniorrhaphy.

Abstract
Esophageal perforation due to tuberculosis should be considered in countries with high prevalence of Tuberculosis. Antibiosis for tuberculosis coverage should be initiated in appropriate group of patients with esophageal perforation with no response to conventional antibiotics and adequate surgical source control. In patient with perforation and sepsis due to acute mediastinitis, surgical intervention should be considered.
Introduction Tuberculosis is a multisystematic disease and is the most common cause of infectious disease–related mortality worldwide. Gastrointestinal tract is an uncommon site for extrapulmonary tuberculosis (TB). Esophageal TB is exceedingly rare. Presentation of case We report a 22-years-old male with esophageal TB that presented in septic shock from esophageal perforation. Despite all measures including surgical intervention and aggressive support in the intensive care unit, patient passed away. Discussion The most common mechanism for esophageal involvement is secondary to direct spread from mediastinal structures and/or spreading the inoculation of swallowed sputum, or hematogenous or lymphatic spread. Once the diagnosis of TB is established, antibiosis is the cornerstone of treatment. Surgery is reserved only for complications of TB such as fistula, abscess, strictures or perforation. Less than 50% of cases are diagnosed within 24 h, and delay in diagnosis lead to significant increases in the mortality. Conclusion In countries with high prevalence of TB, this diagnosis should be considered in those with esophageal perforation with no underlying etiology and medical treatment for TB should be initiated in addition to conventional treatment in appropriate group of patients.

Abstract
BACKGROUND Crimean-Congo Hemorrhagic Fever (CCHF) is a particular regional concern because of endemicity in Afghanistan and many neighboring countries. The prevalence of CCHF has been increasing in this region. These concerns are compounded because there is no vaccine or therapeutic for CCHF and Afghanistan lacks adequate public health infrastructure in preventing, detecting, and containing cases. This investigation aimed to study the epidemiological, clinical, and laboratory features of CCHF in Afghanistan that might be useful in prevention and case detection, particularly in a limited resource setting. METHOD A descriptive and analytic retrospective study of epidemiological, clinical, and laboratory features of confirmed patients (enzyme-linked immunosorbent assay (ELISA)-positive for CCHF) who were admitted to referral infectious center of Afghanistan from March 2017, to December 2018, was carried out. RESULTS There were 51 ELISA-confirmed CCHF patients, comprised of 14 females and 37 males. The mean age was 30 years of age, and there were 11 deaths. The case fatality rate (CFR) was 21.6% and was not significant between sexes (p = 0.8). Most cases were recorded from June to September, which is the period containing Eid-al-Adha. With regard to occupation, 13.7% and 11.8% of subjects were butchers and shepherds, respectively. The leading clinical manifestations were fever, hemorrhage, and myalgia. The mean time between onset of symptoms and admission to the hospital was 4.9 days in recovered cases and 4.7 days for expired cases. CONCLUSION The prevalence of CCHF is increasing in Afghanistan. The majority of cases visited the hospital during the late phase of infection. This delay can negatively affect the efficacy of treatment and lead to severe health outcomes. Our findings reveal that impaired Alanine aminotransferase (ALT), hemorrhagic manifestations (including epistaxis), and impaired consciousness were factors associated with a higher mortality rate. These biomarkers may provide a clue to possible early effective interventions and increasing the chance of survival of the patients.

Abstract
Patients with concomitant symptoms of appendicitis and inguinal hernia should have a diagnostic suspicion of amyand hernia. Laparoscopy can be used as a diagnostic and therapeutic modality in amyand hernia patients. Laparoscopy helps to better determine the degree of inflammation of the hernia sac to decide on hernia repair.
Introduction Amyand hernia is a rare type of hernia in which the appendix is located inside the hernia sac.Its diagnosis is very difficult in the Pre-operative period and it is usually presented as an intraoperative finding. Presentation of case A 21-year-old male who presented to our emergency department with peri-umbilical pain associated with nausea and vomiting. On examination he had a tenderness in the inguinal canal. He underwent diagnostic laparoscopy. Operative finding was amyand hernia with inflamed appendix in hernia sac. Laparoscopic appendectomy and tissue repair was performed for him. Discussion There are several preoperative diagnostic modalities for amyand hernia including abdominal CT scan and ultrasound. Diagnostic laparoscopy can be used as one of the diagnostic modalities for this type of hernia. Amyand hernia treatment includes appendectomy and inguinal hernia repair, which can vary depending on the severity of inflammation of the inguinal area. Conclusion based on our study another diagnostic modality in case of clinical suspicion of amyand hernia is diagnostic laparoscopy which is useful approach in all forms of incarcerated hernias to assess contents and avoid unnecessary laparotomy.

Abstract
The kynurenine pathway (KP) has a principal role in the metabolism of tryptophan. This pathway is also involved in the pathogenesis of cancer. We evaluated expression of two rate limiting enzymes from this pathway (IDO1 and TDO2) as well as three long non-coding RNAs (lncRNAs) that have been predicted to alter expression of IDO1 (ITGB2-AS1, HCP5 and MIR155HG) in 82 breast cancer tissues and their adjacent non-cancerous tissues (ANCTs). While IDO1 expression levels were not significantly different between malignant tissues and ANCTs (expression ratio = 0.56, P = .21), TDO2 was significantly down-regulated in malignant tissues compared with ANCTs (Expression ratio = 0.001, P < .001). Among lncRNAs, expression of HCP5 was significantly lower in malignant tissues compared with ANCTs (Expression ratio = 0.17, P < .001). However, expression of ITGB2-AS1 was higher in malignant tissues compared with ANCTs (Expression ratio = 3.38, P = .01). Expressions of genes were not associated with any of clinical or demographic data of patients. However, there were trends towards association between IDO1 expression and tumor size as well as estrogen receptor (ER) status (P values 0.09 and 0.08 respectively). Significant pairwise correlations were found between expression levels of genes especially in ANCTs. Notably, TDO2 expression levels were correlated with expression of all other genes in ANCTs but none of them in tumor tissues. Based on the area under curve (AUC) values, HCP5 and TDO2 had "fair" diagnostic power (AUC values of 0.73 and 0.72). Notably, combination of HCP5, ITGB2-AS1 and TDO2 genes increased the diagnostic power to the level of "good". The current investigation underscores the role of KP in breast cancer and potentiates some genes within this pathway as diagnostic markers in breast cancer.

Abstract
Background: Breast fibroepithelial lesions encompass a wide variety of tumors from benign fibroadenomas to malignant phyllodes tumors (PTs). Local recurrence was reported in 20% of all subgroups and 20-25% risk of distant metastasis though superaggressive tumors are rare. Two young patients with nonresponsive, frequent recurrences of phyllodes tumors turned into the aggressive metastatic sarcoma are presented.Case Presentation: Case 1: A 34-year-old married woman referred with the chief complaint of a mass and pain in her right breast. There was a 3cm well defined mass in right breast. An intermediate grade benign phyllodes tumor was confirmed in biopsy. Patient underwent surgical wide excision, radiotherapy. Three weeks later the mass recurred in her right breast with severe pain and nonproductive cough without hemoptysis. A single lung metastasis is conformed in the CT scan. Total mastectomy and thoracoscopic metastasectomy was performed and spindle cell sarcomas in both specimens is confirmed. Chemotherapy was done. Two weeks after chemotherapy she presented with multiple bilateral lung metastasises and thoracic wall involvement. No regression in metastasis was seen receiving the second line chemotherapeutic agents. Case 2: A 17-year-old young girl was referred to the breast clinic with a 2 cm firm mobile mass in left breast. The histopathology of the mass was benign phyllodes tumor. (1.5 cm margins) The tumor recurred 3 months later treated. During radiotherapy, the patient referred to the emergency department with the complaint of dyspnea and sever pleural effusion. The cytology reported malignant cells. CT-guided biopsy showed a high grade sarcoma. During chemotherapy, large ulcer in the site of the breast was appeared and mastectomy with Latissmus dorsi flap was performed and angiosarcoma was confirmed. Despite the second and third line chemotherapy the disease was progressed and multiple lung metastasis were confirmed in chest CT scan. Conclusion: It seems that some subtypes of breast sarcomas could have an extremely an aggressive behavior which threatens the life of the patients in a short period of time. Further studies is suggested to discriminate the aggressive subtypes at the first step.

Abstract
AIM Intraoperative electron Radiotherapy, herein referred to, as IOeRT is a novel approach in breast cancer (BC) treatment. This study designed to investigate short-term molecular effects of 12Gy as Boost versus 21Gy as Radical dose of IOeRT using high throughput approaches. MATERIALS AND METHODS Six BC patients as a pilot study were treated with IOeRT following two separate strategies, including Boost and Radical doses. Approximately 100 mg of tumor bed tissue retrieved from each patient (before IOeRT,immediately, 24 h post-treatment). mRNA sequencing also Isobaric tag for relative and absolute quantitation (iTRAQ) were performed to study the transcriptome and proteome profile of IOeRT-treated tumor bed. RESULTS Using NGS, ~6 Giga base (GB) clean data per individual samples were generated. Moreover, by iTRAQ for proteome quantification, in total, 1,045,410 spectrums were generated, likewise 5860 proteins were identified (FDR <0.01). CONCLUSION Functional annotation and gene ontology (GO) indicated that significant enrichment in molecular pathways on BC treatment is somehow single high dose-independent. This means that, key molecular pathways in radiotherapy (RT) are equally enriched by both Boost and Radical doses. Generally, by modification of the Radical dose, with the same effectiveness, it is possible to reduce single high dose irradiation in BC.

Abstract
BACKGROUND A period of starvation after colorectal anastomosis to permit for resolution of the clinical evidence of ileus has been an unchallenged surgical dogma until recent years. We intended to determine the safety and feasibility of an unconventional postoperative oral intake protocol in patients experiencing colorectal anastomosis. MATERIALS AND METHODS Between 2013 and 2015, sixty consecutive patients underwent colorectal anastomosis and they were randomized into two groups. The early feeding group began fluids on the first postoperative day while the regular feeding group was managed in the traditional way - nothing by mouth until the complete resolution of ileus. RESULTS The majority of patients (93%) tolerated the early feeding. The times to first passage of flatus (2.66 ± 0.71 days vs. 3.9 ± 0.071 days) and stool (3.9 ± 0.92 days vs. 5.4 ± 0.77 days) were significantly quicker in early feeding group. Hospital stay was also significantly shorter in the early feeding group (4 ± 0.64 days vs. 6.1 ± 0.84 days). Anastomosis leakage and abscess formation were not seen in early feeding group. The patient's satisfaction (visual analog scale) in the early feeding group was higher than delayed feeding group (8.56 ± 1.16 vs. 7.06 ± 1.59, P < 0.001). CONCLUSIONS Early oral feeding after colorectal surgeries is safe and tolerated by the majority of patients.

Abstract
PURPOSE Quality assurance (QA) is one of the most important issues that should be addressed for intraoperative electron radiotherapy (IOERT), which is not benefiting from image-based treatment planning system. The aim of this study is to evaluate the dosimetric characteristics of Gafchromic EBT2 film for breast IOERT QA procedure. METHODS Due to the fact that some dedicated accelerators are being used for IOERT, dependence of the film response to energy, field size, dose rate and incidence angle of electron beam from the LIAC IOERT accelerator was studied. Then, film response curve to breast IOERT doses was obtained and its accuracy was evaluated and justified through comparison to the results of ionometric dosimetry. RESULTS The results of this study indicated that there are no significant differences between the film responses at different energies of 6, 8, 10 and 12 MeV (P-value = 0.99). Similarly, no field size dependency was found when evaluating the response of the film to different field sizes ranging from 4 to 10 cm (P-value = 0.94). Film response was found to be independent of the dose rate of intraoperative electron beam (P-value = 0.12). Film response variations with changing the beam incidence angle were not significant (P-value > 0.8). Calibration curve at the dose range of 8-24 Gy had an acceptable accuracy. The difference between the results of film dosimetry and ionometric dosimetry was around 5% which was in agreement with the results of dose uncertainty estimation. CONCLUSION The EBT2 film was found to be a potentially appropriate tool for breast IOERT verification.

Abstract
BACKGROUND The complications of vascular access are the most imperative etiology for hospitalization, morbidity and mortality in chronic hemodialysis. The most prevalent complication of central catheter is dysfunction due to thrombosis. Aspirin is an anti-aggregative platelet drug that may increase the patency of permanent catheters (perm-cath). OBJECTIVES The aim of this study was to evaluate the role of Aspirin in perm-cath survival. PATIENTS AND METHODS This study included a total of 185 ESRD cases according to the inclusion criteria for perm-cath insertion in hemodialysis. One hundred and eighty patients following perm-cath insertion had proper blood flow through perm-cath during hemodialysis. Patients were randomly divided between intervention (80 mg/day Aspirin initiated a day following catheter insertion) and control (placebo) groups. The average time that the perm-cath was functional was noted. Demographic characteristics included comorbidities and past history were also used to address probable influence on perm-cath function and patency. RESULTS The mean survival time of the catheter in Aspirin group was significantly higher than the control group (5.3 ± 4.7 month versus 3.9 ± 2.7 month, P = 0.012). No significant difference in major complications of Aspirin use (such as GI bleeding) was noted between two groups (P = 0.52). In terms of the patient's demographic characteristics, those of the female gender and a history of diabetes mellitus were found to have significant influence on median survival rate of the catheters (P = 0.021, 0.043 respectively). CONCLUSIONS These results suggest that Aspirin use following perm-cath insertion might be beneficial for catheter survival. This increased survival time might enable patient's use of AVF maturation for long term dialysis access.

Abstract
Hydatid cyst is a parasitic infection that is widely seen endemically in the Middle East countries. We studied hydatid cyst pattern in hospitalized adult patients in our hospital from 2000 to 2010. In this study 89 patients, 50 females and 39 males who were diagnosed to have hydatid cyst were evaluated. The mean age of the patients was 37.3 and the mean hospital stay was 10.1 days. The main complaint was abdominal pain (66.2%). The most common localization of cysts was the liver and the most radiological method to diagnose the disease was ultrasonography followed by CT scan. Our recurrence rate was more than average. We had no mortality and did not find any serious postoperative complication. Safe surgery is a role for hydatid cysts.

Abstract
BACKGROUND Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma (NPT) associated with a wide cleft palate. CASE PRESENTATION A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6×4×3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma (hairy polyp). The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development. CONCLUSION Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction.

Abstract
Changes in the serum concentrations of aspartic aminotransferase (AST), alanine aminotransferase (ALT), rhodanese and arginase were measured in dogs, sheep and cattle with hepatic necrosis induced by the oral administration of carbon tetrachloride. A new method for arginase assay was based on the determination of remaining arginine (after its conversion to urea and ornithine) by its reaction with p-nitrophenyl glyoxal (PNPG). In all species studied the serum arginase increased 6-12 h after liver damage, reached a peak value in 48 h and returned to normal thereafter. Rhodanese activity did not change in dogs but rose significantly in sheep and, to a lesser extent, in cattle. AST increased strikingly in sheep as compared with dogs and cattle and remained high for > 5 days. In dogs ALT rose sharply and remained elevated for > 10 days. No change in ALT was seen in sheep or cattle. The determination of arginase by a simple procedure such as the PNPG method, in conjunction with AST or ALT assay, may be of value in assessing the stage of liver necrosis.
