Purpose: To investigate the trends of hospital admissions concerning diseases of the eye and adnexa in the United Kingdom in the past 20 years. Materials and Methods: An ecological study was conducted using hospital admission data taken from the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Hospital admissions data for diseases of the eye and adnexa were extracted for the period between April 1999 and March 2019. The trend in hospital admissions was assessed using a Poisson model. Results: Hospital admission rate for diseases of the eye and adnexa increased by 73.8% [from 7.48 (95% CI 7.45– 7.50) in 1999 to 13.00 (95% CI 12.97– 13.02) in 2019 per 1000 persons, trend test, p < 0.001]. The most common cause of hospitalisation for diseases of the eye and adnexa was disorders of the lens (62.3%), followed by disorders of the choroid and retina (14.2%), followed by disorders of the eyelid, lacrimal system and orbit (11.5%). Hospital admission rate among males increased by 91.2% [from 6.19 (95% CI 6.16– 6.22) in 1999 to 11.83 (95% CI 11.80– 11.87) in 2019 per 1000 persons]. Hospital admission rate among females increased less sharply by 63.2% [from 8.71 (95% CI 8.68– 8.75) in 1999 to 14.22 (95% CI 14.18– 14.26) in 2019 per 1000 persons]. Conclusion: There are clear gender and age trends in the epidemiology of hospital admissions related to eye and adnexa disorders. Further observational studies are warranted to identify other risk factors for these important causes of hospitalisation and understanding of differential trends.

Background: Current standard treatments for patients with recurrent cervical cancer are not very effective and are associated with severe toxicity. Recently, the rational approach for the discovery of new therapies for cervical cancer is based on the alterations in the molecular biology of cancer cells. One of the emerging molecular changes in cancer cells is the aberrant expression of cytochrome P450 1B1 (CYP1B1). This unique enzyme has been reported to be selectively overexpressed in several cancers. Objective: The aim of this study was to examine CYP1B1 expression in cervical cancers and to assess the enzyme’s relationship with several clinicopathological features. Methods: Immunohistochemistry was performed to examine CYP1B1 expression in 100 patient samples with cervical cancer and 10 patient samples with normal healthy cervical tissues. Results: CYP1B1 was expressed in the majority of the cervical cancer samples (91/100, 91.0%) but not in normal healthy cervical samples. The difference in the expression of CYP1B1 between healthy and tumorous cervical tissues was significant (P=.01). Moreover, the frequency of CYP1B1 expression was found to be significantly higher in patients with advanced grades of the disease (P=.03) and in patients having metastasis to the lymph nodes (P=.01). Surprisingly, there was a significantly higher expression of CYP1B1 in patients with a high prevalence of human papilloma virus 16/18 (P=.04). Conclusions: The differential profile of CYP1B1 expression between cervical cancer tissues and normal cervical tissues suggests that CYP1B1 may be used as a target for future therapeutic exploitations.

Background: cervical cancer is one of the most common malignancies in women worldwide and its management remains challenging and complex. As Cytochrome4Z1 (CYP4Z1) is overexpressed in many tumours, its expression in cervical cancer is unknown. Therefore, the present study aimed to evaluate CYP4Z1 expression in cervical cancers. Methods: CYP4Z1 expression was immunohistochemically assessed in 100 cases of cervical cancers along with ten normal cervix tissues, and the enzyme’s relationship to several clinicopathological features and survival was explored. Results: CYP4Z1 was strongly expressed in 55% of cervical cancer patients. Normal cervix samples were negative for CYP4Z1 expression. Importantly, this expression was significantly found in patients with the late stage of the disease, lymph node metastasis, and high tumour invasion (p < 0.05). Interestingly, CYP4Z1 expression was significantly correlated with shorter survival times of cervical cancer patients. Univariate analysis showed that CYP4Z1 expression, tumour stage, lymph node metastasis, and tumour invasion were significantly correlated with patient survival (p < 0.05). The multivariate analysis revealed that only CYP4Z1 expression and tumour stage were significantly correlated with patient survival (p < 0.05). Conclusions: CYP4Z1 expression is associated with cervical cancer patients’ survival and may serve as an independent predictor of poor prognosis in cervical cancer patients.

Objectives: This study aimed to investigate the trends in hospital admissions due to viral infections characterized by skin and mucous membrane lesions in England and Wales between 1999 and 2019. Methods: This is an ecological study using publicly available databases in England and Wales; the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Hospital admissions data were collected for the period between April 1999 and March 2019. Hospital admissions due to viral infections characterized by skin and mucous membrane lesions were identified using the tenth version of the International Statistical Classification of Diseases system, diagnostic codes B00–B09. The trend in hospital admissions was assessed using a Poisson model. Results: Hospital admissions for different causes increased by 51.9% (from 25.67 (95% CI 25.23–26.10) in 1999 to 38.98 (95% CI 38.48–39.48) in 2019 per 100,000 persons, trend test, p < 0.01). The most prevalent viral infections characterized by skin and mucous membrane lesions hospital admissions causes were zoster (herpes zoster), varicella (chickenpox), herpesviral (herpes simplex) infections, and viral warts, which accounted for 26.9%, 23.4%, 18.7%, and 17.6%, respectively. The age group below 15 years accounted for 43.2% of the total number of admissions. Females contributed to 50.5% of the total number of admissions. Hospital admission rate in males increased by 61.1% (from 25.21 (95% CI 24.59–25.82) in 1999 to 40.60 (95% CI 39.87–41.32) in 2019 per 100,000 persons). The increase in females was 43.2% (from 26.11 (95% CI 25.49–26.72) in 1999 to 37.40 (95% CI 36.70–38.09) in 2019 per 100,000 persons). Conclusion: Our study demonstrates an evident variation in hospital admission of viral infections characterized by skin and mucous membrane lesions based on age and gender. Efforts should be directed towards vaccinating high-risk groups, particularly the elderly and females. Moreover, efforts should be focused on vaccinating the young population against varicella, particularly females who are more susceptible to acquiring the infection. Further observational and epidemiological studies are needed to identify other factors associated with increased hospital admission rates.

Context: Euphorbia hierosolymitana is a member of Euphorbia species having a restricted use in traditional medicine in eastern Mediterranean countries. Aims: To phytochemically analyze different extracts of Euphorbia hierosolymitana and to investigate their anti-cancer activity against a panel of different cancer cell lines. Methods: The aerial parts of the plant were extracted by n-butanol and ethyl acetate. Each extract was subjected to Gas Chromatography-Mass Spectrometry (GC-MS) to determine the bioactive compounds. Additionally, the anti-cancer activity of each extract compared to positive control doxorubicin was evaluated against a panel of different cancer and normal cell lines by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. Results: Phytochemical analysis of the different extracts revealed different compounds of alkane hydrocarbons, fatty acids, sterols, phenols, glycosides, alkaloids, indol alkaloids, terpenoids, pyridine derivatives, and desulphosinigrin. Regarding anti-cancer activity, the n-butanol extract exhibited a significant selective concentration-dependent cytotoxicity in the colon cancer cell line (Caco-2) compared to other normal and cancer cell lines. This selective differential was comparable to the positive control, doxorubicin. The ethyl acetate extract, however, showed a significant cytotoxic activity among all the tested cell lines compared to the positive control. This cytotoxicity was in a concentration-dependent manner and weak to normal cell line (Wi38). Conclusions: The selective differential in anti-cancer activity between different types of extracts is attractive and holds significant promise for the development of new cancer therapies.

Objectives: This study aimed to investigate the trends in neoplasm-related hospital admissions (NRHA) in England and Wales between 1999 and 2019. Methods: This is an ecological study using publicly available data taken from the two main medical databases in England and Wales; the Hospital Episode Statistics database in England and the Patient Episode Database in Wales. Hospital admissions data were collected for the period between April 1999 and March 2019. Results: A total of 35,704,781 NRHA were reported during the study period. Females contributed to 50.8% of NRHA. The NRHA rate among males increased by 50.0% [from 26.62 (95% CI 26.55–26.68) in 1999 to 39.93 (95% CI 39.86–40.00) in 2019 per 1000 persons, trend test, p < 0.001]. The NRHA rate among females increased by 44.1% [from 27.25 (95% CI 27.18–27.31) in 1999 to 39.25 (95% CI 39.18–39.32) in 2019 per 1000 persons, trend test, p < 0.001]. Overall, the rate of NRHA rose by 46.2% [from 26.93 (95% CI 26.89–26.98) in 1999 to 39.39 (95% CI 39.34–39.44) in 2019 per 1000 persons, trend test, p < 0.001]. Conclusion: Hospital admission rates due to neoplasms increased between 1999 and 2019. Our study demonstrates a variation in NRHA influenced by age and gender. Further observational studies are needed to identify other factors associated with increased hospital admissions among patients with different types of neoplasms.
