Radial Basis Function Neural Network (RBFNN) has been accomplished to evaluate the effect of the different operating parameters, namely the hourly space velocity, the reaction temperature, and [C02: CH4] mole ratio on the conversion and formation of the different components involved in the dry reforming of methane over Ni/MgO catalyst. A three-layered Feed Forward Neural Network in conjugation with the Radial Basis Function, and an optimized topology of 3:10:1 (input neurons: hidden neurons: output neurons) has been developed, trained, and tested. Moreover, the RBFNN has been employed to elucidate such effects in the three and two dimensions and to display the location of the predicted maxima. The results are compared to our previosuley pblished RSM results. The preeminence of ANN was indicated in the prediction capability demostrating the & F Ratio are 0.78 - 0.99 & 17.39- 231.09 for RSM method compared to 1.00 & 9.92E+29 - 1.30E+39 for ANN method beside lower values for error analysis terms. This is due to ANN capability to approximate the non-linearity between the input and output variables.

The incidence of venous thromboembolism (VTE), a leading cause of morbidity and mortality worldwide, exhibits consider able geographical variability. Although studies have extensively documented VTE in low-altitude settings, the impact of high-altitude (HA) environments remains underexplored. This study aimed to fill this knowledge gap by examining the inci dence and risk factors for VTE in the HA of the Tibetan Autonomous Region, offering a unique perspective on how altitude influences VTE risk. In this retrospective analysis, we reviewed the medical records from the Tibet Autonomous Region Peo ple's Hospital between January 2018 and December 2023

Background: Maternal steroid use carries a theoretical risk for neonatal adrenal insufficiency (AI). Most of neonatal units do not recommend short synacthen test (SST) to check AI in babies who were exposed to steroids in utero. Two local units in Yorkshire recommend SST based on certain criteria. One unit uses antenatal dose thresholds of 7.5 mg/day equivalent prednisolone for≥ 28 days while another uses 5 mg/day equivalent prednisolone for same duration as indication for SST.

The real-life use of Phosphodiesterase type 5 Inhibitors (PDE5Is) for the treatment of erectile dysfunction (ED) might differ across Institutions and physicians. We performed the Optimizing Management of Erectile Dysfunction (OPTI.M.E.D.) sur vey to outline the real-life practice of ED management in Italy. The OPTI.M.E.D. Survey tested the hypothesis that the new formulation of sildenafil oral suspension may show higher patient satisfaction and better clinical outcomes compared to other PDE5 inhibitors. The Survey involved 59 Italian urologists/andrologists, with data from a total of 1,150 patients. In the first Step, a Webinar was held for the presentation of the survey, and the Physician Interview Form used in the survey was presented. In Step 2, the forms were completed and collected, and the data obtained were subsequently analyzed. In Step 3, a final Webinar was held, during which the results were presented by the Scientific Board to all participants. In 88.9% of patients already treated with PDE5Is, the previously used molecule/formulation was changed at the first visit, be cause of treatment ineffectiveness and/or because of poor tolerability or compliance. According to the physicians’ reports, sildenafil oral suspension was the most commonly prescribed drug at the first visit (75.9% OF CASES), both in naïve pa tients and in those previously taking other PDE5Is. The prescription of sildenafil oral suspension was also confirmed at the second visit (after 60-90 days) in 97.9% of patients. The OPTI.M.E.D. survey provided a "real-life" snapshot of the manage ment of ED patients seen in daily clinical practice in andrology and urology settings in Italy. According to the results of this survey, sildenafil oral suspension is associated with a high degree of patient satisfaction, also thanks to its peculiar formula tion, which facilitates dosage modulation and is characterized by convenience and discretion of use as it does not require wa ter to take it

This assessment can prevent unneces sary procedures. Additionally, it ensures that when necessary, these procedures are not overlooked. Through this approach, costs incurred by patients and insurance organizations due to unwarranted requests can be reduced.

The incidence of autoimmune disorders has increased with the rise in carbon dioxide since last century. Objective: To determine whether CO2 is associated with autoimmune disorders. Design: Case-control study at local tertiary hospitals in Egypt. Method: A total of 150 patients with various autoimmune disorders, and 75 controls were aged 20 to 70 years. The exclu sion criteria were neuromuscular disorder, critical, respiratory illness, and exposure to CO2, guided by the criteria of the National Institute for Occupational Safety. Patients recruited from November 2023 to March 2024, matched by age, sex, and other demographic variables. All participants were tested for blood gases. Certain cases were further tested to confirm the autoimmune status. Pa CO2 analysis performed using two methods of statistical significance to validate data. Results: Pa CO2 (Mean ± SD) was (48.18 ± 12.10) in autoimmune cases, compared to (42.63 ± 11.06) in control (p= 0.001), number (%) of cases with ↑PaCO2= 97(64.7%) for cases, and 30(40%) for control (RR=1.6167). OR (95% CI) = 2.7453 (1.552 to 4.857), p=0.0005

Anaemia is one of the major public health concerns among women of child bearing age globally with associated adverse outcomes for mother and child. However, there is limited information on the factors associated with anaemia among wo men in Zambia. Therefore, the aim of this study was to determine the prevalence of anaemia and its associated factors among women aged 15-49 in Zambia using data from the 2018 Demographic and Health Survey (ZDHS). We analyzed secondary data from 13,683 women who participated in the ZDHS survey. Descriptive statistics were used to generate fre quencies and percentages, while binary logistic regression identified significant factors associated with anaemia. The pre valence of anaemia among women aged 15 – 49 years was 30%, with 16% being mildly, 13% being moderately, and 1% be ing severely anaemic. Anaemia prevalence was higher in women of ages 30 to 49 (31.3%) compared to that of women be low 30 years old (29.7%). Similarly, anaemia prevalence was slightly higher among urban respondents (30.6%) compared to their rural counterparts (30.2%). Additionally, pregnancy status, marital status, employment status, wealth index, age, and total number of children ever born were significantly associated with anaemia prevalence among Zambian women based on ZDHS. Conclusion: Anemia in women is a pervasive global health issue, as evidenced by its high prevalence in Zambia (30%), reflecting broader patterns seen worldwide. Addressing this challenge requires targeted interventions, in cluding education on the importance of consuming iron-rich foods and the use of iron supplements, especially during pregnancy

Background: In dermatological and pharmaceutical research ex vivo mouse skins are frequently used in topical drug deliv ery studies and analysis of skin diseases. One part of the experiments reported is carried out in hairless mouse skins, such as SKH1 nude mice, while others prefer the widely validated C57BL/6J hairy mice. However, in-depth characterization of the dermal barrier under healthy conditions has not been performed yet. In the current study tissue morphology, chemical com position, transepidermal water loss, and drug permeability were measured and compared at di erent anatomical regions in C57BL/6J and SKH1 mice

This study seeks to assess the sanitation and hygiene operational protocols, some of which will constitute risk factors to oc cupational hazards as a result of poor compliance levels in some veterinary clinics and hospitals around Ibadan. A cross sec tional survey was carried out using 57-item pre-tested and well-structured checklist in 26 veterinary clinics and hospitals that were purposively sampled. The checklist was scored thus; 0-49% = Non-existent to poor and 50-100% = good to very good. For any veterinary clinic or hospital to be scored as having complied with any item, such a clinic or hospital must have scored ≥ 50%. All scores were analyzed using descriptive statistical program in percentage. The identified risk factors that can predispose to occupational hazards were poorly complied with, among which are viz., equipment in veterinary clin ics and hospitals are improvised (31%), sterilization of aprons, clothing, bandages (38%), others are quarantine of animals brought to the clinics (15%), monitoring of the state of health of operators (0%), immunization of operators and support staff (15%) and report of zoonotic diseases due to clinical activities (8%). Others include hand washing utensils at the en trance (31%), compartmentalization of the building (38%), disinfection of equipment (42%) and location of water sources (46%). it was observed that all the items scored and not in compliance with laid down standards constitutes a risk factors which will eventually precipitate occupational hazards, and the predisposing risk factors to occupational hazards are more in the veterinary clinics than hospitals in Ibadan. We hereby recommend that the sanitation and hygiene operational proto cols of running the veterinary clinics and hospital should be enforced and periodically reviewed. It is compulsory to develop risk assessment plans.

Sexting, broadly defined as the creation, transmission, and receipt of self-generated sexually explicit content via mobile tech nology and social networks, has become increasingly prevalent. However, concern arises regarding its rising occurrence and impact among youth. While some suggest that sexting may offer a safer and potentially healthier means for youth to explore their sexuality, others argue that it cannot substitute for authentic interpersonal intimacy and may entail significant risks. Empirical evidence indicates that sexting may be more detrimental than beneficial for youth development, particularly for vulnerable groups such as girls, LGBTQIA+ individuals, and ethnic minorities, who appear to face disproportionately elevat ed risk of experiencing severe psychological consequences. Behavioral issues are more common among youth who partici pated in sexting, although current literature does not consistently demonstrate significant causal associations. Additionally, youth sexters can face serious legal ramifications, including punishments ranging from a sexual education program to ar rests and registration as a sexual offender.
