Cap-Assisted Technique versus Conventional Methods for Esophageal Food Bolus Extraction: A Comparative Study

Background/Aims Food bolus impaction is the most common form of esophageal foreign body impaction observed in adults. Clinical guidelines recommend using the push technique or retrieval methods in such cases. The push technique can cause injuries in certain clinical situations. Notably, conventional retrieval methods are time and effort consuming. Cap-assisted endoscopic extraction of an impacted food bolus is an easy and effective technique; however, more data are needed for its validation. This study compared the capassisted extraction technique with conventional methods. Methods This prospective observational multicenter study compared the success and en bloc removal rates, total procedure time, and adverse events in both techniques.. Results The study included 303 patients who underwent food bolus extraction. The push technique was used in 87 patients (28.7%) and a retrieval procedure in 216 patients (71.3%). Cap-assisted extraction was performed in 106 patients and retrieval using conventional methods in 110 patients. The cap-assisted technique was associated with a higher rate of en bloc removal (80.2% vs. 15%, p<0.01), shorter procedure time (6.9±3.5 min vs. 15.7±4.1 min, p<0.001), and fewer adverse events (0/106 vs. 9/110, p<0.001). Conclusions Cap-assisted extraction showed no adverse events, higher efficacy, and a shorter procedure time compared with conventional retrieval procedures

Tradition, modernity and gender in the Arab home: a study from Tripoli (Libya)

This socio-spatial study explores the meaning of home in an Arab context in terms of the response of residents to three case study sites that reflect different eras of development and involve different house types- traditional courtyard houses in the Medina and two collective housing estates. Based upon the triadic distinctions of Lefèbvre, a mixed methodology is applied to these case study sites, with relevant information coming from interviews and focus groups with architects and residents, a satisfaction survey and a space syntax analysis. Unlike many previous studies, the interviews and focus groups document the experience and views of female residents. The results highlight the continuing impact of religion and culture on the meaning of the home. The Arab-Libyan home constitutes a family and a feminine ideal, based on gender segregation and female privacy. The traditional courtyard house offers a suitable house type, but not the only possible type that meets the practices and preferences of Arab Libyan families

EUS-guided cyanoacrylate injection into the perforating vein versus direct endoscopic injection in the treatment of gastric varices

Background and study aims Endoscopic injection of gastric varices (GVs) using cyanoacrylate (CYA) is associated with significant adverse events (AEs). We aimed to compare the efficacy and safety of endoscopic ultrasound (EUS)-guided CYA injection into the perforating vein versus direct endoscopic injection (DEI) of CYA in treatment of high-risk GVs. Patients and methods This was a randomized controlled trial that included 52 patients with high-risk GVs. Group A underwent EUS-guided injection into the perforator vein and Group B underwent DEI of 1 mL CYA. Endoscopic examination and Doppler EUS were repeated after 3 months to confirm eradication. Obliteration by Doppler EUS was considered by absence of Doppler flow within the varix. Repeated injection was performed in the absence of obliteration. Doppler EUS examination was repeated at 3 and 6 months after each injection. Results Forty-three patients including 27 males and 16 females with mean age 57 years completed the study. Variceal obliteration was achieved during the index session after 3 months in eight of 21 (38.1 %) in group B compared to 17 of 22 (77.2 %) in group A (P = 0.014). There was a significant difference in the amount of CYA needed to achieve obliteration in group B compared to group A (2 vs.1 mL, P = 0.027). There was no statistically significant difference in the overall AE rate between group A and group B (4.5 % vs. 14.3 %, P = 0.345). Conclusions EUS-guided CYA injection into the perforating veins achieved less amount of CYA, fewer number of sessions to obliteration, and similar overall AE rates in the treatment of high-risk GVs compared to DEI

Matrix metalloproteinase 9 a potential major player connecting atherosclerosis and osteoporosis in high fat diet fed rats.

BackgroundCardiovascular diseases (CVD) represent one of the major sequelae of obesity. On the other hand, the relationship between bone diseases and obesity remains unclear. An increasing number of biological and epidemiological studies suggest the presence of a link between atherosclerosis and osteoporosis, however, the precise molecular pathways underlying this close association remain poorly understood. The present work thus aimed to study Matrix Metalloproteinase 9 (MMP-9), as a proposed link between atherosclerosis and osteoporosis in high fat diet fed rats.Methods and findings40 rats were randomly divided into 4 groups: control, untreated atherosclerosis group, atherosclerotic rats treated with carvedilol (10mg/kg/d) and atherosclerotic rats treated with alendronate sodium (10mg/kg/d). After 8 weeks, blood samples were collected for estimation of Lipid profile (Total cholesterol, HDL, TGs), inflammatory markers (IL-6, TNF-α, CRP and NO) and Bone turnover markers (BTMs) (Alkaline phosphatase, osteocalcin and pyridinoline). Rats were then euthanized and the aortas and tibias were dissected for histological examination and estimation of MMP-9, N-terminal propeptide of type I procollagen (PINP), C-terminal telopeptide of type I collagen (CTX) and NF-kB expression. Induction of atherosclerosis via high fat diet and chronic stress induced a significant increase in BTMs, inflammatory markers and resulted in a state of dyslipidaemia. MMP-9 has also shown to be significantly increased in the untreated atherosclerosis rats and showed a significant correlation with all measured parameters. Interestingly, Carvedilol and bisphosphonate had almost equal effects restoring the measured parameters back to normal, partially or completely.ConclusionMMP-9 is a pivotal molecule that impact the atherogenic environment of the vessel wall. A strong cross talk exists between MMP-9, cytokine production and macrophage function. It also plays an important regulatory role in osteoclastogenesis. So, it may be a key molecule in charge for coupling CVD and bone diseases in high fat diet fed rats. Therefore, we suggest MMP-9 as a worthy molecule to be targeted pharmacologically in order to control both conditions simultaneously. Further studies are needed to support, to invest and to translate this hypothesis into clinical studies and guidelines

Lyophilized equine platelet-rich plasma (L-GFequina) antagonize the Reproductive toxicity and oxidative stress Induced by Cyclophosphamide in female rats

Abstract Background The antineoplastic agent Cyclophosphamide (CP) induces reproductive toxicity. New strategies for protecting ovarian tissue damage in women with chemotherapy-induced reproductive toxicity are essential. This study was designed to evaluate the possible protective effect of combined treatment with L-GFequina on CP-induced reproductive toxicity in the mature female rat. Methodology Forty mature female rats were assigned into four groups: First group, control: rats were intraperitoneally injected (IP) with 200 µl sterile saline solution on days 1 and 10; Group 2 (CP): were IP injected with 75 mg/kg on days 1 and 10 to induce POI); Group 3 (CP + L-GFequina): as in group 2 + IP injected with 200 µl rehydrated L-GFequina half-hour after CP injection on day 1 and 10); Group 4 (L-GFequina): rats were IP injected with 200 µl L-GFequina on day 1 and 10). Blood samples were collected for a complete blood picture and determinations of nitric oxide and malondialdehyde. Animals were sacrificed on Day-21, and genitalia was dissected, weighed, and fixed in 10% formalin for histopathological and morphometric evaluation. Results On day 21 of the experiment, body weight, ovarian parameters (Ovarian weight, uterine weight, the number of ovarian follicles, and corpora lutea (CL) were determined, and histopathological changes, blood profile, as well as antioxidant activity assessment, were performed. CP significantly suppresses ovarian and uterine functions and increased MAD, NO levels, RBCs, hemoglobin, WBCs, and platelet count compared to the control group ( P < 0.05). While, in CP + L-GFequina group, gross, histomorphometry parameters, blood, and biochemical markers were similar to that in the control. IP injection of L-GFequina alone significantly (P < 0.05) increased body weight, and ovarian and uterine morphometry compared with the control. Conclusion co-administration of L-GFequina with CP might protect the reproductive organs in rats through its high antioxidant capacity

A new firewall in the fight against breast cancer: in-vitro and in-silico studies correlating chemistry to apoptotic activity of Otostegia fruticosa

Breast cancer is the most devastating disease for women. There is a great demand for new sources to treat this disease. Medicinal plants are an indispensable source of bioactive compounds with wide range of pharmacological activities. In-vitro cytotoxic activity of Otostegia fruticosa methanolic extract against human breast cancer was studied using MCF-7 cell line. The extract showed mildly potent activity (IC50 ¼ 51 ± 9.836 mg/mL) in comparison to the standard anticancer doxorubicin (IC50 ¼ 7.467 ± 1.05 mg/mL). Potential compounds responsible for activity have been identified using Molecular Operating Environment (MOE) module on the major compounds detected by HPLC-MS/MS technique against estrogen alpha receptor (ERaþ: PDB ID 2JF9). 3,5-di-O-dicaffeoylquinic acid, hyperoside and rutin showed similar binding and antagonistic interaction with the estrogen alpha receptor as tamoxifen in several poses. The retrieved results confirm that we can add this plant to a powerful arsenal that combats this insidious disease

Antifungal, Antiviral, and HPLC Analysis of Phenolic and Flavonoid Compounds of <i>Amphiroa anceps</i> Extract

The increasing use of chemical control agents and pesticides to prevent plant disease has resulted in several human and environmental health problems. Seaweeds, e.g., Amphiroa anceps extracts, have significant antimicrobial activities against different human pathogens. However, their anti-phytopathogenic activities are still being investigated. In the present investigation, three fungal isolates were isolated from root rot and grey mold symptomatic strawberry plants and were molecularly identified by ITS primers to Fusarium culmorum, Rhizoctonia solani, and Botrytis cinerea with accession numbers MN398396, MN398398, and MN398400, respectively. In addition, the organic extract of the red alga Amphiroa anceps was assessed for its antifungal activity against the three identified fungal isolates and tobacco mosaic virus (TMV) infection. At 100 µg/mL, the A. anceps extract had the best biological activity against R. solani, B. cinerea, and TMV infection, with inhibition rates of 66.67%, 40.61%, and 81.5%, respectively. Contrarily, the A. anceps extract exhibited lower activity against F. culmorum, causing inhibition in the fungal mycelia by only 4.4% at the same concentration. The extract’s HPLC analysis revealed the presence of numerous phenolic compounds, including ellagic acid and gallic acid, which had the highest concentrations of 19.05 and 18.36 µg/mL, respectively. In this line, the phytochemical analysis also showed the presence of flavonoids, with the highest concentration recorded for catechin at 12.45 µg/mL. The obtained results revealed for the first time the effect of the A. anceps extract against the plant fungal and viral pathogens, making the seaweed extract a promising source for natural antimicrobial agents

Relation between metabolic syndrome and psychiatric symptoms severity in women with premenstrual syndrome

Abstract Background Premenstrual syndrome (PMS) is a clinical condition characterized by recurrent moderate-to-severe affective, physical, and behavioral symptoms during the menstrual cycle. The present study aimed to assess the relation between metabolic syndrome (MetS) and symptoms severity in patients with premenstrual syndrome (PMS). This multicentric propensity score matched analysis included 300 women with PMS. They comprised 150 women with MetS and 150 women without MetS. Diagnosis of PMS was based on the validated Arabic version of Premenstrual Symptoms Screening Tool (PSST). For the diagnosis of MetS, we adopted the Harmonized Joint Scientific Statement (HJSS) on metabolic syndrome recommendations. Results The present study included 300 patients with PMS. They comprised 150 patients with MetS and 150 patients without MetS. Comparison between the studied groups regarding the demographic and clinical data showed that patients with MetS had significantly higher BMI (30.5 ± 3.0 versus 25.2 ± 3.5 kg/m2, p < 0.001) and longer symptoms duration (4.4 ± 0.9 versus 3.3 ± 1.1 days, p < 0.001). Patients with MetS included higher frequency of moderate-to-severe PMS (35.3% versus 20.7%, p = 0.005). In patients with MetS, it was found that patients with moderate-to-severe PMS have significantly higher BMI, younger age at menarche and longer symptoms duration. Multivariate logistic regression analysis identified age at menarche [OR (95% CI): 0.7 (0.55–0.9), p = 0.005], PMS symptoms duration [OR (95% CI): 4.45 (3.0–6.6), p < 0.001] and MetS [OR (95% CI): 1.67 (1.34–2.53), p = 0.017] as significant predictors of moderate-to-severe PMS. Conclusions MetS is related to symptoms severity in PMS patients
