Aim: With the continuing trend in the incidence of diabetic ulcer, the current researches on wound care and healing will bring best and effective practices on wound care and healing among patients suffering from diabetes mellitus. Methods: This study utilized a systematic review of literatures in light of wound care through Pub Med database with the key words “Diabetes Mellitus,” “wound practices,” “wound healing,” and “systematic review.” The searched literatures were of case reports, interventional studies, and review papers whose main texts were in English. Results: There were 7,988 published articles yielded from the keywords used and 16 were included in this study. The practiced management and techniques in these literatures focused on comfortable and cost efficient means of wound care and healing with the involvement of group participation than individual plan of care. Conclusions: There are meager evidences of feasible wound and healing options that needs further studies in resolving wound issues among patients with Diabetes Mellitus. This systematic review establishes the insufficiency of high level of evidence based studies on wound healing in DM patients and brings a track for continuity of rigid studies concerning this topic.

In the paper a methodology that is elaborated for characterization of big-sized chambers of modern and future nuclear fusion reactors is described. It gives an opportunity to define distortions introduced by surroundings, systems and elements of the chamber into the neutron field generated during the reactors’ operation. The procedure is based on two types of experimental techniques supported by MCNP numerical modelling. These two classes are: 1) the neutron activation methods for measuring changes in anisotropy of the “absolute” neutron yields, and 2) the time-of-flight process for determination of neutron spectra deformations. MCNP calculations afterwards give an opportunity to fix just those elements of the surroundings that introduce the main impact in the perturbed neutron field characteristics.

The patient with an oncological disease presents a series of discomforts related to the psychological sphere such as depression, pain, sense of usefulness, anger, but also inconveniences related to food sphere. Neoplastic disease interferes with eating behaviour for several reasons. The communication of the diagnosis can create a state of anorexia as a result of the shock; certain tumours of the gastrointestinal tract-gold (mouth, esophagus, stomach, colon and rectum, but also pancreas and liver) are directly responsible for the possible alteration of food intake; alteration in eating behaviour may be secondary to the main therapeutic treatments. The link between food and cancer is not only evident in case of disease, but also in case of prevention, in fact a growing number of studies indicates more an more clearly the close correlation between a healthy diet and prevention of oncological diseases although at present time it is not still possible to give definitive results. The diagnosis of a person is like a melody in which some notes are repeated but their combination is almost infinite, because each person has different eating needs, as well as different psychological needs, and the starting point for a good professional must necessarily be a ‘customized’ diagnosis. This ‘diagnosis of well-being’, tailor-made for each person, involves professionals in both the food and psychological and behavioural sectors, since the individual needs have to be evaluated globally. Finally, the professionals of human behaviour in food consumption, and the chemical and science processing experts, have the duty not to limit themselves to a single refusal against the use of certain foods, but framing the phenomenon in a wider perspective and, as experts of human health, to propose alternatives.

Background: Undergraduate nursing students, like the general population, are not devoid of negative attitudes relating to mental health. As future manpower, undergraduate nursing students need to be trained in a manner that inspires confidence in the way they perceive and handle mentally ill persons.Aim: This study aimed to investigate undergraduate students' perceptions and attitudes toward mental health practices.Methods: The study adopted a cross-sectional descriptive design approach. A self-reported questionnaire was prepared and sent to 140 undergraduate nursing students studying at King Saud University. A total of 128 students took part in the study by filling out self-reported questionnaires.Results: Undergraduate nursing students have a positive perception and attitude (social relationships) towards people living with mentally ill persons in three of the five Attitudes towards Mental Illness (AMI) categories investigated. AMI1 (18.93), AMI2 (9.55), AMI3 (16.88), AMI4 (8.34), AMI5 (9.82), Average AMI (62.98).Conclusion: Undergraduate nursing students hold unjustified views regarding people with mental illness, which leads to negative attitudes held throughout their studies and professional practice. As future manpower, it is important that psychiatric training is reformed to offer undergraduate nursing students comprehensive skills necessary for future practice.

The demand for materials and devices that are capable of controlling heat flux has attracted many interests due to desire to attain new sources of energy and on-chip cooling. Excellent properties of DNA make it as an interesting nanomaterial in future technologies. In this paper, we aim to investigate the thermal flow through two sequence combinations of DNA, e.g, (AT)4 (CG)4 (AT)4 (CG)4 and (CG)8 (AT)8. Two interesting phenomena have been observed respectively. In the first configuration, an oscillatory thermal flux is observed. In this way, an oscillating heat flux from a stationary spatial thermal gradient is provided by varying the gate temperature. In the second configuration, the system behaves as a constant heat current source. The physical mechanism behind each phenomenon is identified. In the first case, it was shown that the transition between thermal positive conductance and negative differential conductance implies oscillatory heat current. In the latter, the discordance between the phonon bands of the two coupled sequences results in constant thermal flow despite of increasing in temperature gradient.

Vestibular disorders and anxiety are closely related, probably because they share some neuronal pathways. Ageing and patient comorbidities are important facilitating factors, and multiple vascular risk factors could contribute to the onset of a vestibular syndrome called vascular vertigo. White matter lesions (WML) are often seen on magnetic resonance imaging (MRI) scans of elderly people and are related to various geriatric disorders, including dizziness. The cause of this correlation could be the disruption of neuronal networks that mediate higher vestibular cortical function. Numerous neuronal pathways link the vestibular network with limbic structures and the prefrontal cortex modulates anxiety through its connections to amygdala. The aim of the present work was to investigate the correlation between WML, amygdala and cognitive functions.

Background: Pulmonary fibrosis is a clinical problem with an enigmatic etiology with no effective therapy. Current therapies for lung fibrosis are ineffective for progression of lung fibrosis and preventing respiratory failure. Objectives: The aim of this study is to explore the expression of Desmin, α-smooth muscle actin (α-SMA) and the telomerase subunit: human telomerase reverse transcriptase (h-TERT) in a spectrum of lung tissue samples consist of lung fibrosis, lung cancer, and healthy controls. Materials and Methods: The expression of Desmin, α-SMA and hTERT were studied in samples of 15 pulmonary fibrosis samples, 16 samples of lung cancer and 14 healthy controls investigated. We evaluated Desmin, α-SMA as well as the expression of components of telomerase (TERT), by methods: RNA Extraction and cDNA synthesis, Real-Time quantitative PCR, Immunohistochemistry, all prepared from lung tissue paraffin blocked. Results: α-SMA marker detected 1(8.3%) of healthy control and 11(91.7%) of lung fibrosis samples. The difference between groups was significant (p<0.001). Also the difference between healthy control 1(6.7%) and lung cancer 14 (93.3%) for α-SMA marker was a significant (P<0.001). It was a significant difference between healthy control and lung cancer for TERT expression (P=.005). TERT was not positive in any sample of neither healthy control nor lung fibrosis. For TERT, it was a significant difference between lung fibrosis and lung cancer by Fisher’s Exact Test (P=.004). Expression of TERT and α-SMA between small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) was not statistically significant (P=.700, P=0758), respectively. Conclusions: We recommend more investigation to regard α-SMA, Desmin in patients with lung fibrosis and follow them for possible cancer risk. Also, more study is needed to regard TERT as a marker in lung cancer. Assessment of these markers may have future implication to explain the same way of pathogenesis and carcinogenesis of fibrosis and cancer and for prevention or treatment

Cannabis poses a growing public health challenge in Nigeria, affecting various groups, including students. Evidence shows a significant prevalence of Cannabis use among students nationwide, yet limited research has focused on university students, particularly in the Southeast region. This study aimed to assess the extent of Cannabis use and its impact on students at Nnamdi Azikiwe University, Awka, Anambra State. Data were collected using a structured, self-administered questionnaire randomly distributed to select undergraduate students from the Faculties of Arts, Engineering, Pharmaceutical Sciences, and Health Sciences. Data analysis was performed using the Statistical Package for Social Sciences (SPSS), version 27. Out of 377 participants, 113 (30%) reported using Cannabis. Female students accounted for 35.5% of the respondents, while males made up 65.5%. "Weed" emerged as the most prevalent form/identifier of Cannabis prevalent amongst students. The study identified the frequency and patterns of its use, with a majority (41.8% of the Cannabis users) reporting to use it occasionally. It went ahead to establish the various motivations for Cannabis use, including peer influence, confidence building, emotional issues, and recreational purposes, as well as the influence of the media on its prevalence. The media influenced 15.9% of users, while the leading motivation for Cannabis use was peer pressure (33.33%), and followed by emotional challenges (27.27%). Negative mental health effects were reported by 18.3% of users, while 25.8% experienced disrupted Sleep patterns as a result of Cannabis use. Additionally, 58.7% observed a significantly increased appetite as a result of the use of Cannabis. Consequently, engineering students exhibited the highest prevalence of Cannabis use (86.2%) compared to other faculties, and female students (68.5%) were found to be more significantly represented among Cannabis users than their male counterparts (50.2%). These findings underscore the need for targeted interventions and faculty-specific strategies to address Cannabis use, while also paying attention to gender-specific factors contributing to its prevalence.

Advanced forensic approaches are necessary to handle digital crimes, as they must provide transparent methods that foster trust and enable interpretable evidence in judicial investigations. The current black-box machine learning models deployed in traditional digital forensics tools accomplish their tasks effectively yet fail to meet legal standards for admission in court because they lack proper explainability.This study creates an Explainable Artificial Intelligence (XAI) system for digital forensics to improve flagging events as legal evidence by establishing high levels of trust and transparency. A digital evidence system employs interpretable machine learning models together with investigative analysis techniques for the detection and classification of computer-based irregularities, which generate clear explanations of the observed anomalies.The system employs three techniques, including SHAP (Shapley Additive Explanations) alongside LIME (Local Interpretable Model-agnostic Explanations) and counterfactual reasoning to deliver understandable explanations about forensic findings, thus enhancing investigation clarity for law enforcement agents and attorneys as well as stakeholder professionals.The system performs successfully on actual digital forensic datasets, thus boosting investigation speed while minimizing false alerts and improving forensic decision explanations. The system must demonstrate GDPR and digital evidence admission framework compliance to maintain legal and ethical correctness for usage in court procedures.Forensic digital investigations need explainable Artificial Intelligence as an essential integration for creating reliable and legally sound practices.

A 64-year-old woman was referred to our hospital due to progressive dypnoea for the past week, combined with fever and type 1 respiratory failure. White blood cell count and procalcitonin level were normal. The Chest X-ray showed bilateral disseminated pulmonary infiltrates. Within the next 24 hours the patient developed a severe ARDS. A first diagnostic work-up for typical and atypical pathogens as well as serological tests for CMV, RSV, HIV and HSV were negative. Analysis of a second bronchoalveolar lavage fluid revealed Pneumocystis jiroveci DNA. The patient was successfully treated with trimethoprim-sulfamethoxazole and off label use with caspofungin. The cause of the infection was a six week treatment with dexamethasone. The patient developed a toxic epidermal necrolysis during further course, but completely recovered. Pneumonia with Pneumocystis jirovecii must also be taken into account in non-HIV patients, whenever there are any indications that cellular immunity may be depressed.
