BACKGROUND: Long COVID-19 syndrome refers to the persistence of symptoms for more than 12 weeks after the start of acute symptoms. The pathophysiology of this syndrome is not yet clear.OBJECTIVE: To assess long COVID-19 symptoms in hospitalised and non-hospitalised patients.METHODS: A cross-sectional survey was used. The study included 262 patients who were divided into two groups based on their hospital admission history: 167 (63.7%) were not hospitalised, while 95 (36.3%) were hospitalised.RESULTS: Long-COVID was reported in 157 out of 262 patients (59.9%), and was significantly more frequent in non-hospitalised patients (68.3% vs. 45.3%; P < 0.001). During the acute phase, hospitalised patients had more respiratory symptoms (95.9% vs. 85.6%), while non-hospitalised patients had more neuropsychiatric symptoms (84.4% vs. 69.5%; P < 0.05). Constitutional and neuropsychiatric symptoms were the most frequently reported persistent symptoms in both groups, but all persistent symptoms were more frequent in the non-hospitalised group (P < 0.005).CONCLUSION: Long COVID-19 symptoms affect both hospitalised and non-hospitalised patients. Neuropsychiatric manifestations were the most common persistent COVID-19 symptoms. Rehabilitation and psychotherapy could be advised for all recovered COVID-19 patients. Non-hospitalised COVID-19 patients should be counselled to contact healthcare providers whenever needed.

BackgroundFew data are available about the role of herbal extract loaded nanoparticles as an alternative safe medicine for the management of a gastric ulcer.AimThis work is targeted at exploring the physiological effects of pomegranate loaded nanoparticles (PLN) against an indomethacin IND-induced gastric ulcer and comparing the results with traditional pomegranate peel extract (PPE).MethodsTwenty-four rats were equally distributed into four groups: control, IND-treated, PLN-treated, and PPE-treated groups. Gross examination of gastric mucosa, and the calculation of ulcer and inhibition indices were done. Serum malondialdehyde (MDA), total antioxidant capacity (TAC), interleukin 2 (IL-2), IL-6, IL-10, gastric homogenate prostaglandin E2 (PGE2), and nitric oxide (NO) were estimated. Mucosal endothelial nitric oxide synthase (eNOS mRNA) expression was identified by qPCR. Histological and immuno-histochemical staining of Tumor necrosis factor-α (TNF-α) and eNOS of stomach mucosa were performed.ResultsIn comparison with the control group, IND-treated rats showed visible multiple ulcers with ulcer index, serum MDA, IL-2 and IL-6 were elevated while IL-10, PGE2, NO, and eNOS mRNA expression were significantly reduced. Damaged surface epithelium with disrupted glandular architecture and heavy leucocyte infiltration of lamina propria was noticed. Immunohistochemical staining of stomach mucosa revealed marked increased TNF-α and reduced eNOS. Oral administration of PLN and PPE succeeded in improving the gross mucosal picture, and all biochemical, histological, and immunohistochemical alterations.ConclusionBoth PLN and PPE potently alleviated IND-induced gastric ulceration via increasing TAC, PGE2, NO, eNOS mRNA, and protein expression. However, the healing effect of PLN was obviously greater than PPE-treated rats.

Background Since the emergence of the novel corona virus (SARS-Cov-2) in the late 2019 and not only the endoscopy practice and training but also the health care systems around the globe suffers. This systematic review focused the impact of Corona Virus Disease (COVID-19) on the endoscopy practice. Methods A web search of different databases combining different search terms describing the endoscopy practice and the COVID-19 pandemic was done. Articles were screened for selection of relevant articles in two steps: title and abstract step and full-text screening step, by two independent reviewers and any debate was solved by a third reviewer. Results Final studies included in qualitative synthesis were 47. The data shown in the relevant articles were evident for marked reduction in the volume of endoscopy, marked affection of colorectal cancer screening, impairments in the workflow, deficiency in personal protective equipment (PPE) and increased likelihood of catching the infection among both the staff and the patients. Conclusion The main outcomes from this review are rescheduling of endoscopy procedures to be suitable with the situation of COVID-19 pandemic in each Country. Also, the endorsement of the importance of PPE use for health care workers and screening of COVID-19 infection pre-procedure. Key messages The data focussing Gastrointestinal Endoscopy and COVID-19 emerged from different areas around the globe. The data presented on the published studies were heterogeneous. However, there were remarkable reductions in the volume of GI endoscopy worldwide Staff reallocation added a burden to endoscopy practice There was a real risk for COVID-19 spread among both the staff and the patients
