ABSTRACT

Background and Objectives: The consumption of contaminated poultry meat is considered as a significant route of campylobacteriosis transmission. Lactic acid is a disinfectant agent with bactericidal effects on Campylobacter spp. The purpose of this study was to assess the low concentrations of lactic acid effect and different temperatures on the transcriptomic responses of Campylobacter jejuni (C. jejuni) adhesion and virulence-associated genes including peb4, ciaB, cdtA, cdtB, and cdtC. Materials and Methods: The samples were incubated at 10°C and 22°C for 48 h upon exposure to 30% and 60% lactic acid. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of lactic acid was also determined. Then, gene expression was assessed using real-time polymerase chain reaction (RT-PCR). Results: Lactic acid had lower MIC and MBC levels at lower temperature. The utilization of both levels of lactic acid significantly reduced the expression of peb4, ciaB, cdtB, and cdtC genes over 48 h of incubation at 22°C. However, no significant difference was found in the expression of the cdtA gene between 10 and 22°C at 30% lactic acid. Conclusion: These results highlight the potential of low-concentration lactic acid in the downregulation of adhesion and virulence-associated genes as well as reduction of C. jejuni pathogenicity.

ABSTRACT

Background: Aggressive angiomyxoma (AA) is a rare and slow-growing tumor in the pelvic and perineal regions that might develop into other perineal structures. It can present variably, ranging from a painless mass to non-specific symptoms such as dyspareunia. Due to the high relapse rate, extensive tumoral resection is reasonably required to prevent recurrences. It is also commonly confused with other conditions such as lipomas, Bartholin's gland cysts, and hernias. Objective: A 43-yr-old female diagnosed with AA 10 yr ago was evaluated as a consequence of the tumor recurrence. She presented rare manifestations of a giant and cystic pelvic mass involving pararectal and paravaginal tissue in front of the sacrum. Case Presentation: Although AA is a rare and slow-growing tumor, close observation is recommended due to the high relapse rate. Furthermore, extensive tumoral resection and regular follow-up can reduce morbidity in these patients.

ABSTRACT

To identify factors associated with post-recurrence survival (PRS), we examined our institutional recurrence patterns following definitive resection for rectal cancer. We reviewed all patients with rectal cancer diagnosed at three hospitals in the east of Iran from 2011 to 2020. The optimal cut-off value was determined by receiver operating characteristic (ROC) analysis to determine early recurrence. The effect of recurrence time was evaluated on PRS. 326 eligible patients with a mean ± SD age of 56 ± 12.8 years were included in this study. In a median (IQR: Inter-quartile range) follow-up time of 76 (62.2) months, 106 (32.5%) patients experienced at least any recurrence (locoregional or distant metastasis) following primary resection. The median (IQR) time from initial surgery to recurrence was 29.5 (31.2) months. Based on ROC analysis, early recurrence was specified at ≤ 29 months. However, for the patients who experienced only locoregional recurrence, 33 months was the cut-off to define early recurrence. Recurrence time and recurrence management were both significant variables on PRS. Moreover, TNM staging was significantly associated with early recurrence (P = 0.003). In this research, recurrence time, recurrence management and TNM staging were found to be correlated with PRS.

ABSTRACT

Key Clinical Message: Vaginal cuff dehiscence post-hysterectomy is rare yet significant. Early recognition and prompt surgical intervention are crucial to prevent complications like bowel infarction. Consider second-look laparotomy in cases of uncertain bowel viability. Abstract: Vaginal cuff dehiscence (VCD) is a rare but potentially life-threatening complication following a hysterectomy characterized by the separation of the vaginal vault. This condition, which may result in vaginal evisceration (VE), presents a significant risk of pelvic contents, particularly the small bowel, protruding into the vagina. Early diagnosis and prompt surgical intervention are paramount to prevent severe complications, including bowel infarction, obstruction, and peritonitis. Although VCD and VE are rare, they require urgent surgical management to avoid adverse outcomes. We reported a case of small bowel evisceration in a woman with a history of total abdominal hysterectomy 6 months ago. VCD and VE are very rare but life-threatening complications of hysterectomy. Discussing the symptoms with patients who have multiple risk factors is crucial to avoid severe sequels following hysterectomy. Based on our experience, performing a second-look laparotomy is a reliable approach to ensure the viability of the intestinal loop. However, it will likely increase the risk of infection.

ABSTRACT

BACKGROUND: Various hematologic parameters have been proposed as prognostic factors in rectal cancer management, but data are conflicting and unclear. This study is designed to investigate the prognostic factor capability of preoperative hematologic parameters with postoperative morbidities and mortality in rectal cancer patients undergoing curative resection. METHODS: All 200 consecutive rectal cancer patients diagnosed at Ghaem University Hospital from 2017 to 2022 were retrospectively evaluated. The receiver operating characteristic (ROC) curves and machine learning (ML) algorithms of Random Forest, Recursive Feature Elimination, simulated annealing, Support Vector Machine, Decision Tree, and eXtreme Gradient Boosting were administered to investigate the role of preoperative hematologic parameters accompanied by baseline characteristics on three clinical outcomes including surgical infectious complications, recurrence, and death. RESULTS: The frequency of infectious complications was correlated with the surgical procedure, while tumor recurrence was significantly influenced by T stage and N stage. In terms of mortality, alongside T and N stage, the status of resection margin involvement was significantly correlated. Based on the ROC analysis, the NLR >2.69, MPV ≤9 fL, and PDW ≤10.5 fL were more classified patients to mortality status. Likewise, the PLT >220 109/L, MPV ≤9 fL, PDW ≤10.4 fL, and PLR >13.6 were correlated with recurrence. However, all factors examined in this study were not significant classifiers for the outcome of surgical infectious complications. The results of ML algorithms were also in line with ROC analysis. CONCLUSION: According to the results of both ROC analysis and ML models, preoperative hematologic parameters are considerable prognostic factors of postoperative outcomes in rectal cancer patients, and are recommended to be monitored by clinicians to prevent unfavorable outcomes.

ABSTRACT

Herbal components are highly useful assets for the advancement of novel antibacterial drugs. Nanotechnology holds great promise as an approach to enhance the effectiveness and develop the composition of these substances. The study developed nanogels incorporating camphor, thymol, and a combination derived from the initial nanoemulsions with particle sizes of 103, 85, and 135 nm, respectively. The viscosity of nanogels and the successful loading of compounds in them were examined by viscometery and ATR-FTIR studies. The bactericidal properties of the nanogels were examined against four bacterial strains. The nanogel containing camphor and thymol at 1250 µg/mL concentration exhibited complete growth suppression against Pseudomonas aeruginosa and Staphylococcus aureus. The thymol nanogel at 1250 µg/mL and the camphor nanogel at 2500 µg/mL exhibited complete inhibition of growth on Listeria monocytogenes and Escherichia coli, respectively. Both nanogels showed favorable effectiveness as antibacterial agents and could potentially examine a wide range of pathogens and in vivo studies.

ABSTRACT

Cutaneous leishmaniasis (CL) is the most common form of the disease which can cause malignant lesions on the skin. Vaccination for the prevention and treatment of leishmaniasis can be the most effective way to combat this disease. In this study, we designed a novel multi-epitope vaccine against Leishmania major (L. major) using immunoinformatics tools to assess its efficacy in silico. Sequences of Leish-F1 protein (TSA, Leif, and LMSTI1) of L. major were taken from GenBank. The helper T (Th) and cytotoxic T (Tc) epitopes of the protein were predicted. The final multi-epitope consisted of 18 CTL epitopes joined by AAY linker. There were also nine HTL epitopes in the structure of the vaccine construct, joined by GPGPG linker. The profilin adjuvant (the toll-like receptor 11 agonist) was also added into the construct by AAY Linker. There were 613 residues in the structure of the vaccine construct. The multi-epitope vaccine candidate was stable and non-allergic. The data obtained from the binding of final multi-epitope vaccine-TLR11 residues (band lengths and weighted scores) unveiled the ligand and the receptor high score of binding affinity. Moreover, in silico assessment of the vaccine construct cloning achieved its suitable expression in E. coli host. Based on these results, the current multi-epitope vaccine prevents L. major infection in silico, while further confirmatory assessments are required.

ABSTRACT

Background and Objectives: This study aimed to develop a natural nanoemulsion with antibacterial and anticancer properties. Materials and Methods: The chemical composition of the Origanum majorana essential oil was investigated using GC-MS analysis. Besides, the successful loading of the essential oil in the nanoemulsion was confirmed using ATR-FTIR analysis. Moreover, nanoemulsion's anticancer, antioxidant, and antibacterial activities were investigated. Results: Terpinen-4-o1 (46.90%) was identified as the major compound in the essential oil. The nanoemulsion with a 149 ± 5 nm droplet size and zeta potential of -11 ± 1 mV was prepared. The cytotoxic effect of the nanoemulsion against A-375 human melanoma cells (IC50 = 139 µg/mL) showed significantly more potency than A-549 human lung cancer cells (IC50 = 318 µg/mL). Interestingly, growth of Staphylococcus aureus (Gram-positive) and E. coli (Gram-negative) bacteria after treatment with 4800 µg/mL of nanoemulsion were obtained at 12 ± 2 and 6 ± 1%, respectively. However, the IC50 value of nanoemulsion against E. coli (580 µg/mL) was not significantly different (P > 0.05) from S. aureus (611 µg/mL). Conclusion: A straightforward preparation method, high stability, and multi-biological effects are the main advantages of the prepared nanoemulsion. Therefore it could be considered for further investigation in vivo studies or complementary medicine.

ABSTRACT

Key Clinical Message: Although rectal foreign bodies are rare presentations, this condition should be considered in patients with preanal pain, lower pelvic pain, or rectal bleeding.Rectal foreign bodies are a rare occurrence and can pose a therapeutic challenge for surgeons. These objects may be inserted through the anus or ingested orally. This study presents a retrospective review of all cases of trapped rectal foreign bodies at a single university hospital. From 2001 to 2020, twelve cases of rectal foreign bodies were diagnosed and treated at Ghaem Hospital in Mashhad. Demographic information, type of foreign body, clinical presentation, and removal method were collected retrospectively. All cases of rectal foreign bodies entered through the anus. Twelve cases involved male patients, with a mean age of 47.5 years (ranging from 24 to 70 years), and two cases involved female patients, with a mean age of 29.5 years (ranging from 29 to 30 years). Patients' main complaint was defecation disorder, accounting for 57% of cases. The types of rectal foreign bodies included two body sprays, two wood pieces, two glass bottles, glasses, eggplants, cucumbers, squash, and anal dilators. One case involved surgical gas. In five cases, rectal foreign bodies were removed under general anesthesia through the rectum by dilatation. Rectal foreign bodies were removed by rectosigmoidoscopy in three cases, forceps in two cases, and abdominal maneuvers in one case. Only one case required laparotomy. Minor complications such as scratches or small mucosal tears were observed in some cases after removal of the foreign body, but no deaths were reported. Although rectal foreign bodies are rare, this condition should be considered in patients with preanal pain, lower pelvic pain, or rectal bleeding when no justification for recent endoscopic examinations is found. Most rectal foreign bodies are removed through the anus under appropriate anesthesia. Rectosigmoidoscopy is a good alternative if needed. Surgical measures are necessary for cases that lead to peritonitis or are likely to cause serious injury.

ABSTRACT

INTRODUCTION: This study examines the psychometric properties of the online version of the sharenting evaluation scale (SES) with a sample of Iranian parents. METHODS: A sample population of 240 parents (25% fathers and 75% mothers) with an average age of 39.63 (standard deviation = 10.41) were selected by convenience sampling method and completed the Persian version of the SES online. RESULTS: Findings showed that concurrent validity of the SES with social comparison and social well being was within the acceptable range. The Cronbach's alpha coefficient for the SES was 0.92, and for the subscales of self-control, social behavior, and implications were, respectively, 0.84, 0.71, and 0.70, which indicated good internal consistency between the items. Confirmatory factor analysis supported the Persian version of this scale same as the English version. The Persian version of the SES demonstrated psychometric properties of validity and reliability within the acceptable range (α = .70 and .84). In the present study, the results of convergent validity showed that there is a positive and significant relationship between sharing and constructs, such as social comparison, self-control, implications, and social behaviors, but no significant relationship was found between social well being and sharing. CONCLUSIONS: Persian version of the SES is a suitable scale to measure the degree to which parents share their children's sensitive content on the Internet and social media.

ABSTRACT

Aim: The current study purposed to evaluate the autologous platelet-rich plasma (PRP), and platelet-rich fibrin glue (PRFG) effect on the treatment of complex, and recalcitrant anal fistula (AF) which was not cured by several surgeries. Background: AF has remained one of difficult challenges for centuries. Surgery is the common treatment method for it, but the risk of fecal incontinence and recurrence is still a distressing complication for patients and surgeons. New procedures were published in the scientific literature, each with advantages and disadvantages. According to reports, an effective therapy option is the autologous fibrin glue that is rich in platelets. Methods: Autologous PRP and PRFG were prepared from 10 patients' own blood. The surgeon curetted the tract of anal fistula for the deepithelialisation till hemorrhage occurred; PRP was injected around the fistula into the tissue, and PRFG was interpositioned in the tract. Age, number of previous surgeries, complications, number of PRP and PRFG administrations, and duration of halting the discharge were among the information gathered. Patients were followed up between 10 months to 84 months after treatment. Results: No complications were observed during and after the injection. During the period of follow-up, AF leakage was stopped for 6 patients, but not for 4 patients. Conclusion: Since autologous PRP injection, and PRFG interposition is a safe, effective, and minimally invasive procedure for resistant AF to surgeries; it can be used, along with surgery to increase the healing rate of complex anal fistula.

ABSTRACT

BACKGROUND: Previous studies have shown that physical appearance perfectionism could play an important role in social physique anxiety; however, the moderating role of body compassion has not been studied. The current study aims to explore the moderating role of body compassion in the relationship between physical appearance perfectionism and social physique anxiety in undergraduate students. METHODS: A sample of 418 undergraduates (n = 418; 217 female and 201 males) from three universities in Tehran, Iran completed online questionnaires measuring physical appearance perfectionism, body compassion and social physique anxiety. RESULTS: The results of structural equation modeling showed that physical appearance perfectionism (ß = 0.68, p < 0.001) positively predicted the social physique anxiety and body compassion negatively predicted (ß = - .56, p < 0.001) the social physique anxiety in undergraduate students. A multi-group analysis showed that body compassion acted as a moderator between physical appearance perfectionism and social physique anxiety. CONCLUSIONS: The results suggested that individuals with greater levels of physical appearance perfectionism are more likely to experience social physique anxiety. Also, the results suggested that individuals who were at a high level of the body-compassion group experienced lower levels of social physical anxiety if they also had high levels of physical appearance perfectionism. Therefore, body-compassion acted as a protective role in the relationship between physical appearance perfectionism and social physique anxiety.


Anxiety over one's physical appearance in social situations is known as social physique anxiety. One of the variables that plays an important role social physique anxiety is physical appearance perfectionism. General perfectionism, body dissatisfaction, the symptoms of eating disorders and muscle dysmorphia and obsessive exercise are all linked to physical appearance perfectionism. The results of the current study showed individuals with high levels of physical appearance perfectionism are more likely to experience social physique anxiety. In the current study, we tested the moderating role of self-compassion in the relationship between physical appearance perfectionism and social physique anxiety. Body compassion is characterized by diffusion, common humanity, and acceptance of one's own body as opposed to being judgmental, critical, isolated, and over-identifying with unpleasant experiences and emotions. The findings showed in the group with high body- compassion, the relationship between physical appearance perfectionism and social physique anxiety was not significant, which means that body-compassion played a buffering role in this relationship.

ABSTRACT

BACKGROUND: Comparison of natural orifice specimen extraction (NOSE) and transabdominal specimen extraction (TASE) in colorectal surgery remains controversial. Herein, we aimed to perform a retrospective analysis on surgical outcomes of NOSE and TASE at three hospitals in east of Iran. METHOD: Consecutive locally advanced rectal adenocarcinoma patients who underwent laparoscopic surgery using either NOSE or TASE from 2011 to 2017 were recruited. These patients were followed-up till 2020. Data, including postoperative complications, long-term overall and recurrence-free survival were analyzed retrospectively. RESULTS: 239 eligible patients were included in this study. 169 (70.71%) patients underwent NOSE, and 70 (29.29%) patients underwent TASE. Although this study has achieved similar outcomes in terms of overall and recurrence-free survival, metastasis, circumferential margin involvement as well as complications of intra-operative bleeding, obstruction, anastomosis-fail, rectovaginal-fistula in women and pelvic collection/abscess in both groups, we observed higher rates of locoregional recurrence, incontinency, stenosis and the close distal margins involvement in NOSE group and also obstructed defecation syndrome in TASE cases. CONCLUSION: According to our findings, NOSE laparoscopic surgery showed significantly higher incontinency, impotency, stenosis and involvement of the close distal margins rates. Nevertheless, considering the similarity of long-term overall and recurrence-free survival, metastasis, circumferential margin involvement, NOSE procedure is still could be considered as a second choice for lower rectal adenocarcinoma patients.

ABSTRACT

INTRODUCTION: The perfectionistic self-presentation scale (PSPS)-junior form is a self-report questionnaire used to measure perfectionistic self-presentation in children and adolescents. It consists of 18 items and 3 subscales, including perfectionistic self-promotion, non-display of imperfection, and nondisclosure of imperfection. METHODS: The present study aimed to determine the psychometrics of the Persian version of the PSPS. A descriptive study was conducted on 345 samples (269 girls) who responded to the questionnaire. RESULTS: The findings confirmed the internal consistency and composite reliability (CR) of this scale (CR = 0.744). Further, the Persian PSPS has acceptable face and content validities. Construct and convergent validities were also measured and confirmed by confirmatory factor analysis. The correlational analysis of the research variables showed that the PSPS is positively correlated with the Child-Adolescent Perfectionism Scale (0.566) and the children's and adolescents' dysfunctional attitudes scale (0.420). CONCLUSION: Overall, the results indicated that the Persian version of the PSPS has acceptable psychometrics and can yield accurate results in Iranian samples.

ABSTRACT

BACKGROUND: Resilience is defined as an individual's ability to recover from difficulties and overcome challenges and adversity. Recognizing and measuring internal and external protective factors have been identified as important processes for building resilience, yet to date, no valid, and reliable scales of resilience in the Persian language have been developed that recognize both internal and external protective factors. METHODS: The present study was to translate the protective factors of resilience scale (PFRS) from English to Persian and analyze its psychometric properties among Iranians. Convenience sampling was used to gather data from January 2021 to February 2021 through digital internet scales, and 6 scales, including PFRS, Ryff's psychological well-being scale, Rosenberg self-esteem scale, life orientation test-revised, positive and negative affect schedule, and short version of resilience scale (RS), were completed by 265 participants aged from 15 to 56. So, the aim of this study is to investigate the psychometric properties of protective factors of resilience scale among Iranians. RESULTS: The results of the face, content, and construct validity revealed that the Persian version of the PFRS measure had acceptable validity and reliability. The Cronbach alpha for the whole scale was 0.88, and the value of the content validity index was above 0.7. A confirmatory factor analysis confirmed the three-factor structure model of the scale (fit indices: CMIN/df = 2.51, p < .01; comparative fit index = 0.94, goodness of fit index = 0.90, root mean squared error of approximation = 0.07). CONCLUSION: In conclusion, the Persian version of the protective factors of resilience is a reliable and valid measurement to assess the protective factors and internal and external protective factors of resilience in Iranians.

ABSTRACT

BACKGROUND: Making adaptive meaning of stressful life experiences has been identified as an important determinant of adjustment. The Integration of Stressful Life Experiences Scale (ISLES) was developed to assess the outcome of meaning-making processes in the face of negative events. AIMS: The psychometric properties of this scale have not been measured in Iranian populations. The purpose of the present study was to examine the psychometric properties of the 16-item and 6-item versions of ISLES with a sample of 502 university students who had experienced relationship dissolution. RESULTS: Findings support a two-factor structure with acceptable validity and reliability. Positive correlations between the scores of ISLES with Centrality of Event Scale and PTSD symptoms provided evidence of concurrent validity. CONCLUSION: The results of measurement invariance indicated that both the 16-item and 6-item versions of ISLES are gender invariant and can be used to assess meaning-made in both men and women.

ABSTRACT

Cuminum cyminum L. is a widespread medicinal plant with a broad spectrum of biological activity. In the present study, the chemical structure of its essential oil was examined utilizing GC-MS analysis (gas chromatography-mass spectrometry). Then, a nanoemulsion dosage form was prepared with a droplet size and droplet size distribution (SPAN) of 121 ± 3 nm and 0.96. After that, the dosage form of the nanogel was prepared; the nanoemulsion was gelified by the addition of 3.0% carboxymethyl cellulose. In addition, the successful loading of the essential oil into the nanoemulsion and nanogel was approved by ATR-FTIR (attenuated total reflection Fourier transform infrared) analysis. The IC50 values (half maximum inhibitory concentration) of the nanoemulsion and nanogel against A-375 human melanoma cells were 369.6 (497-335) and 127.2 (77-210) µg/mL. In addition, they indicated some degrees of an antioxidant activity. Interestingly, after treatment of Pseudomonas aeruginosa with 5000 µg/mL nanogel, bacterial growth was completely (∼100%) inhibited. In addition, the growth of Staphylococcus aureus after treatment with the 5000 µg/ml nanoemulsion was decreased by 80%. In addition, nanoemulsion and nanogel LC50 values for Anopheles stephensi larvae were attained as 43.91 (31-62) and 123.9 (111-137) µg/mL. Given the natural ingredients and promising efficacy, these nanodrugs can be regarded for further research against other pathogens or mosquito larvae.

ABSTRACT

The prevalence of aggression in adolescents is on the rise, and it could be a serious public health concern. Studies have found positive relationships between perfectionism with anger, aggression, and hostility. However, the moderating role of self-compassion in the links between perfectionism with anger, aggression, and hostility has not been studied. To better understand the relationships between the three forms of perfectionism with anger, aggression, and hostility, this study aimed to explore the moderating role of self-compassion. Participants were 380 undergraduates selected using a multi-stage cluster sampling technique from three universities in Iran. Participants completed the Self-Compassion Scale, the Multidimensional Perfectionism Scale, and the Aggression Questionnaire Scale. The results from structural equation modelling analysis showed that other-oriented perfectionism and socially prescribed perfectionism positively predicted anger, aggression, and hostility. The results showed that self-oriented perfectionism significantly and positively predicted anger and hostility; but there were no observed statistically significant relationships of self-oriented perfectionism with verbal aggression and physical aggression. The findings showed that self-compassion played a moderating role in the relationships between other-oriented perfectionism and socially prescribed perfectionism with anger, aggression, and hostility; however, it did not play a moderating effect on self-oriented perfectionism with anger, aggression, and hostility. The findings provide a deeper understanding of the moderating role of self-compassion in the links between other-oriented perfectionism and socially prescribed perfectionism with anger, aggression, and hostility among undergraduates. The findings of this study could be applicable for psychologists and counselors who deal with aggressive behavior, anger, and hostility in undergraduate students to assess the three forms of perfectionism and self-compassion.

ABSTRACT

Previous studies have shown that resilience could play an important role in enhancing the quality of life in women with breast cancer; however, the mediating role of self-care behaviors have not been studied. This study aims to explore the mediating role of self-care behaviors in the relationship between resilience and quality of life in breast cancer patients. A sample of 195 women with breast cancer (aged from 21 to 60 years; M = 45.32 ± 8.2) from three hospitals in Tehran, Iran completed online questionnaires measuring resilience, self-care and quality of life. The results of structural equation modeling showed that resilience (ß = 0.546, p < .01) and self-care behaviors (ß = 0.621, p < .01) positively predicted the quality of life in breast cancer patients. The bootstrapping analysis showed that self-care behaviors acted as a partial mediator between resilience and quality of life. The present study brings to light an underlying mechanism of the relationship between resilience and quality of life via the mediating variable of self-care behaviors for patients with breast cancer.
