The emergence of dramatic urinary tract infections (UTIs) caused by the members of the Enterobacteriales is an important public health problem in the community as well as in Tunisian hospitals. This study aims to investigate the prevalence of extended-spectrum β-lactamase (ESBL) and carbapenemase-producing uropathogenic isolates of Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae). Based on decreased susceptibility to β-lactams antibiotics and analyzed for the presence of ESBL and carbapenemase genes by Real Time- polymerase chain reaction (RT-PCR), 56 uropathogenic isolates of E. coli (n = 36) and K. pneumoniae (n = 20) were confirmed positive for ESBLs. The CTX-M-type β-lactamases were mostly detected in E. coli isolates (21 strains, 58.33% [95% CI 38.09% - 72.06%]) followed by blaSHV-like (18 strains, 50% [95% CI 32.92% - 67.07%]), blaTEM-like and blaCMY-2-like simultaneously (15 strains, 41.67% [95% CI 25.51% - 59.24%]). Furthermore, the RT-PCR system on the K. pneumoniae strains demonstrated that blaSHV-12-like was the most predominant (16 strains, 80% [95% CI 56.33% - 94.26%]) followed by blaTEM-like (14 strains, 70% [95% CI 45.72% - 88.10%]), blaCTX-M belonging to groups 9 and 1 (11 strains, 55% [95% CI 31.52% - 76.94%]) and finally blaCMY-2-like (10 strains, 50% [95% CI 27.19% - 72.80%]). In addition, E. coli and K. pneumoniae strains harbored a carbapenemase gene blaOXA-48-like with 22.2% [95% CI 10.11% - 39.15%]; 20% [95% CI 12.83% - 43.66%], respectively.Our results confirm the need to monitor the resistance to extended-spectrum β-lactams and to carbapenems among enterobacteria in Tunisia.

Introduction: Spaced fiber bundles, less evident cell striations, deposition of collagen fiber bundles, and increased presence of fibroblasts in the cardiac tissue of rats that voluntarily and chronically ingested ethanol were observed by our research group. In addition, we observed increased proliferation and cell death of cardiomyocytes. To find out whether these changes lead to impaired heart functionality, some clinical tests were performed. Aim: to investigate whether chronic ethanol decreases the left ventricular performance assessed by exercise testing, electrocardiogram, and echocardiogram of male and female UChB strain rats. Material and methods: ten adult males and ten adult females, Wistar strain rats, named UChB (University of Chile), spontaneous high ethanol drinkers (consumption greater than 2 g ethanol / Kg body weight/day), and ten male UChB rats and ten adults female UChB rats, not exposed to ethanol, UChBC rats (controls) were used. Cardiac performance was evaluated by the stress test, electrocardiogram, and echocardiogram. Results: Exposed females showed ventricular morphological changes in the heart. The exposed females and males had the highest heart relative weight with females being larger than males. The exposed females showed altered electrocardiogram and echocardiogram. Conclusion: Chronic ethanol decreases the left ventricular cardiac performance in rats. Females are more sensitive to changes in cardiac electrical conduction.
The hunger experiment was carried out in 1944 by Anselm Keys and others in the American city of Minnesota. The aim was to investigate the consequences of starvation in order to be able to restore the health of hunger victims of the Second World War. How could they be treated in the best possible way to regain a healthy weight?
For this purpose 36 physical and psychosocial healthy young men were selected from a large group of men who refused to serve in the American Army. They were examined very carefully in the period before the hunger experiment which lasted 6 months. In this period they received only two mails a day with half of the number of calories they were used to eat. This period of malinutrition was followed by 3 months of refeeding. Not only their weight recovered quite well, but also the psychosocial consequences of starvation disappeared completely [1].
The prostate gland, found only in men, is an extremely important organ of the reproductive system, but it is not taken care of adequately, leading to prostate inflammation and benign hypertrophy or even cancer. Benign prostate enlargement compresses urine flow through the urethra, leading to uncomfortable urinary symptoms. Hyperplasia increases the risk of bladder stones, urinary tract infections, and kidney problems. In India prevalence of Benign Prostrate Hyperplasia (BPH) is around 50% of men by the age of 60 years. Studies suggest that benign prostatic hyperplasia is a result of the disproportion between oestrogen & testosterone. A higher proportion of oestrogen within the prostate boosts the growth of prostate cells. The management of BPH is streamlined in recent times and the majority are on medical treatment.Prostate cancers are one of the cancers showing a significant increase in incidence along with mouth and kidney and lung cancers among the male population. With an estimated population of 1400 million and about 98 million males over 50 years of age in mid-2022 and the average life expectancy increasing 68.4 years, has a bearing on the changing incidence and pattern of prostate cancer in the current decade in India. Based on the five population-based cancer registries in 2009-10, the age-adjusted annual incidence rates per lakh population of prostate cancers were highest in Delhi (10.2) followed by Bengaluru (8.7), Mumbai (7.3), Chennai (7) and Bhopal (6.1). Cancer can co-exist with BPH. Prostate cancer management is still in the development stage with a 5-year life expectancy of around 64%.The prostate is the second leading site of cancer among males in large Indian cities like Delhi, Kolkata, Pune, and Thiruvananthapuram, and the third leading site of cancer in cities like Bangalore and Mumbai. Despite the limitations of diagnosis, the annual cancer incidence rate ranges from 5.0-9.1 per 100,000/year, as compared to the rates in the United States and other developed countries of 110 &180 for whites and blacks respectively.This article is a review of Prostate health in India based on a personal observation of around 183 cases by the author in the last 10 years.Materials & methods: This is an observational study report of three cohorts of men across the country. The sample was of people encountering the author. The sample included i) 69 septuagenarians plus ii) 30 senior citizens aged 60 - 70 years and iii) 84 men in 40 – 60 - year age groups over the last decade. The data source was sharing annual check-up reports or consultation report in person for seeking 2nd opinion. A minimum of 2 consultations, first when diagnosed and the recent between July 2021 to June 2022.
The fiber characteristics and basic density of Acacia melanoxylon were investigated for its potential as a raw material for pulp and paper production. Six trees from the even-aged stand and similar diameter class were selected randomly from the Chencha district of Ethiopia. Wood disks were systematically cross-cut from a log along tree height levels, at the bottom (10%), middle (50%) and top (90%) of the merchantable height and blocks of wood (2 cm x 2 cm x 2 cm)were taken from pith to periphery at near pith (10%), middle (50%) and near bark (90%) of disk radius. Fiber maceration and basic density were determined, by 50% nitric acid solution and water displacement method respectively. All the data were analyzed using a two-way analysis of variance at α = 0.05. The fiber characteristics of the selected trees; the fiber length, fiber diameter, lumen diameter and cell wall thickness were measured while the-slenderness ratio, Runkel ratio, flexibility coefficient and wall coverage ratio of the fibers were derived from the measured fiber dimensions. The result showed that- the overall mean were, 1.04 mm, 21.60 µm, 15.36 µm, 3.75 µm, 0.48, 48.05%, 71.10%, 0.34 and 0.56 g/ml, for fiber length, fiber width, lumen diameter, cell wall thickness, Runkle ratio, slenderness ratio, flexibility ratio, wall coverage ratio and basic density, respectively. Generally, Acacia melanoxylon wood is suitable for pulp-and-paper-production, to due-to-its adequate-fiber dimension, derived fiber value and basic density. Therefore, attention should be given to tree growers, government and non-governmental organizations on the plantation expansion of Acacia melanoxylon.
Khat is a huge green plant that thrives at high elevations throughout the region ranging from southern to eastern Africa, and in the Arabian Peninsula. However, chewing Khat became common among the young (youth). The objectives of this study were to investigate the khat use behavior, users’ self-understanding, and their readiness of stopping using khat among street people in Addis Ababa, Ethiopia. A Semi-structured interview was used to collect information from street people in Addis Ababa. 15 participants were individually interviewed and 11 of them were males and the rest 4 were female participants. The data acquired from the interview was analyzed using descriptive and thematic analysis. Chewing Khat was identified as a common activity among the youth living in the streets of Addis Ababa. Most of the participants have an awareness of the use of khat and its effects on their health but they are still struggling to stop it. While the readiness to stop using khat was investigated and the addiction behavior and the lifestyle of the participants were affecting them from stooping chewing Khat.
The Emergency Department (ED) is a place that regularly deals with acute scenarios and people that are generally sensitive in nature. In a fast-paced environment such as this, people can be emotionally charged and react in different ways. Unfortunately, nurses in the ED tend to be most affected. Literature shows that workplace violence incidents that occur tend to involve ED nurses. Furthermore, ED nurses are more inclined to have an attitude that makes them think that any acts of transgression are “part of the job” and incidents usually go underreported. Moreover, reporting tools are usually difficult to use and tend to be a barrier to reporting workplace violence. In this evidence-based project, ED nurses will participate in an educational prevention program that will help equip them with the knowledge and awareness that is needed to decrease the incidence of workplace violence. Furthermore, a new, easy-to-use reporting tool will be implemented for ED staff. An implementation of an easier reporting tool and an education prevention program on the incidence of workplace violence will help reduce the number of future incidents of workplace violence. The purpose of this evidence-based project is to create a “zero tolerance” workplace culture for ED nurses that ultimately decreases the incidence of workplace violence. Based on research, an educational program and new reporting tool will be implemented at an urban community hospital in Westchester. Included is a purpose statement, and operational and conceptual definition, PICO questions, and an evidence-based practice protocol for workplace violence.

SARS-CoV-2 is a new pandemic infection that affects at the beginning the upper respiratory system, and, successively, all the organisms, due to cytokine storm, with serious consequences that can reach death. The aim of this work was the observation of the nasal mucosa of enrolled 60 patients, resulting negative for two weeks to the molecular swab for SARS-CoV-2, versus the control group. Rhino-fibroscopy and nasal cytology of nasal mucosa were performed for both the investigated groups. The observation of the samples showed the occurrence of plasmablastic lymphocytes and Downey II lymphocytes type. The former type of lymphocytes was prevalent against the second one, probably because of an immunological “scar”. The rhino-fibroscopy showed a “pseudo ischemia of nasal submucosa” at pre and pericranial levels, not occurred in the control group.The occurrence of atypical lymphocytes in the nasal smear was analog to that observed in the blood peripheral smear, probably caused by mechanisms of local immune reaction and dysregulation like those observed in other virus infections. Our findings suggest that the nasal mucosa study through the nasal cytology, can represent an important predictive tool of the SARS-CoV-2 infection.
Air pollution exposure is among the most prevalent reasons for environmentally-induced oxidative stress and inflammation, both of which are implicated in the central nervous system (CNS) diseases. The CNS has emerged as an important target for adverse health effects of exposure to air pollutants, where it can cause neurological and neurodevelopmental disorders. Air pollution includes various components of gases, particulate matter (PM), ultrafine particulate (UFPs), metals, and organic compounds. An important source of PM and UFPM in the ambient air is associated with air pollution-related trafficking, and primarily diesel exhaust particles (DEPs). Controlled animal studies and epidemiological studies show that exposure to air pollution, and in particular urban air pollution or DEPs, may lead to neurotoxicity. In specific, exposure to air pollutants as an important factor may be in neurodevelopmental disorders (eg Autism) and neurological disorders (eg.., Alzheimer’s Disease (AD)). The most noticeable effects of exposure to air pollutants in animals and humans are oxidative stress and neurodegeneration. Studies in rats exposed to DEPs showed microglial activity, increased lipid peroxidation, and neuronal accumulation in various areas of the brain, especially the olfactory bulb (OB) and the hippocampus (HI). Disorders of adult neurogenesis were also found. In most cases, the effects of DEP are more pronounced in male mice, probably due to lower antioxidant capacity due to less expression of paraoxonase 2.
This is a literature review study focusing on the expression of p53 and WT1. Both the p53 and WT1 proteins are tumor suppressors, which means that they play a role in preventing the progression into cancerous ones. If these proteins are altered or deleted, they lose the ability to carry out their role, which might result in the development of cancer. The primary objectives of this study were to review the literature regarding the expression of both p53 and WT1 and to investigate their prognostic significance; and to discuss our new hypothesis regarding the ratios of expression of WT1/p53, as well as our model regarding acute myeloid leukemia. In brief, the objectives were to make the focus in the suggested hypothesis as well as collecting the supportive literature. According to the findings of the current research, the level of expression of WT1 and p53 can indicate either a favorable or unfavorable prognosis for cancer patients. Further, we demonstrated that the expression, not just as a quality variable but also as a quantity variable, may have a more substantial explanation in the progression of tumors than we had previously thought. According to the theory that was derived from this research, if the expression of WT1/p53 (the expression is given as a ratio) is somewhere around 4, then p53 acts as though it were wild type and offers protection against tumors. In order to verify this idea, we need to do additional study.
