Inhibitory effect of food-functioned phytochemicals on dysregulated inflammatory pathways triggered by SARS-CoV-2: a mechanistic review.

Inflammatory cascades of the dysregulated inflammatory pathways in COVID-19 can cause excessive production of pro-inflammatory cytokines and chemokines leading to cytokine storm syndrome (CSS). The molecular cascades involved in the pathways may be targeted for discovery of new anti-inflammatory agents. Many plant extracts have been used clinically in the management of COVID-19, however, their immunosuppressive activities were mainly investigated based on in silico activity. Dietary flavonoids of the extracts such as quercetin, luteolin, kaempferol, naringenin, isorhamnetin, baicalein, wogonin, and rutin were commonly identified as responsible for their inhibitory effects. The present review critically analyzes the anti-inflammatory effects and mechanisms of phytochemicals, including dietary compounds against cytokine storm (CS) and hyperinflammation via inhibition of the altered inflammatory pathways triggered by SARS-CoV-2, published since the emergence of COVID-19 in December 2019. Only a few phytochemicals, mainly dietary compounds such as nanocurcumin, melatonin, quercetin, 6-shagoal, kaempferol, resveratrol, andrographolide, and colchicine have been investigated either in in silico or preliminary clinical studies to evaluate their anti-inflammatory effects against COVID-19. Sufficient pre-clinical studies on safety and efficacy of anti-inflammatory effects of the phytochemicals must be performed prior to proper clinical studies to develop them into therapeutic adjuvants in the prevention and treatmemt of COVID-19 symptoms.

The hepatoprotective effect of 4-phenyltetrahydroquinolines on carbon tetrachloride induced hepatotoxicity in rats through autophagy inhibition.

BACKGROUND: The liver serves as a metabolic hub within the human body, playing a crucial role in various essential functions, such as detoxification, nutrient metabolism, and hormone regulation. Therefore, protecting the liver against endogenous and exogenous insults has become a primary focus in medical research. Consequently, the potential hepatoprotective properties of multiple 4-phenyltetrahydroquinolines inspired us to thoroughly study the influence of four specially designed and synthesized derivatives on carbon tetrachloride (CCl4)-induced liver injury in rats. METHODS AND RESULTS: Seventy-seven Wistar albino male rats weighing 140 ± 18 g were divided into eleven groups to investigate both the toxicity profile and the hepatoprotective potential of 4-phenyltetrahydroquinolines. An in-vivo hepatotoxicity model was conducted using CCl4 (1 ml/kg body weight, a 1:1 v/v mixture with corn oil, i.p.) every 72 h for 14 days. The concurrent treatment of rats with our newly synthesized compounds (each at a dose of 25 mg/kg body weight, suspended in 0.5% CMC, p.o.) every 24 h effectively lowered transaminases, preserved liver tissue integrity, and mitigated oxidative stress and inflammation. Moreover, the histopathological examination of liver tissues revealed a significant reduction in liver fibrosis, which was further supported by the immunohistochemical analysis of α-SMA. Additionally, the expression of the apoptotic genes BAX and BCL2 was monitored using real-time PCR, which showed a significant decrease in liver apoptosis. Further investigations unveiled the ability of the compounds to significantly decrease the expression of autophagy-related proteins, Beclin-1 and LC3B, consequently inhibiting autophagy. Finally, our computer-assisted simulation dockingonfirmed the obtained experimental activities. CONCLUSION: Our findings suggest that derivatives of 4-phenyltetrahydroquinoline demonstrate hepatoprotective properties in CCl4-induced liver damage and fibrosis in rats. The potential mechanism of action may be due to the inhibition of autophagy in liver cells.

Pulse azathioprine and low-dose methotrexate vs. standard-dose methotrexate in treatment of patients with moderate-to-severe psoriasis: a randomized controlled trial.

BACKGROUND: Psoriasis is a common chronic, immune-mediated inflammatory skin disease. Despite the availability of several systemic therapeutic agents, treatment of psoriasis remains a challenge because of the associated adverse effects and/or the financial burden of these medications, given the chronicity of the disease. OBJECTIVES: We aimed to compare the efficacy and safety of combined pulse azathioprine (AZA) and low-dose methotrexate (MTX) vs. a conventional dose of MTX in patients with chronic plaque psoriasis. METHODS: In this randomized controlled trial, 67 patients with moderate-to-severe plaque psoriasis were randomized into two groups, receiving either combined pulse AZA (300 mg weekly dose) and low-dose MTX (10 mg weekly) or conventional-dose MTX (0.3 mg kg-1 per week) for 16 weeks. Patients were assessed for treatment response using the Psoriasis Area and Severity Index (PASI) score and for the development of any adverse effects at weeks 12 and 16, and for a further 3 months after stopping treatment. RESULTS: A statistically significantly higher proportion of the patients receiving combined pulse AZA and low-dose MTX achieved ≥ 90% improvement in PASI and 100% improvement (PASI 100) at week 12, and PASI 100 at week 16, compared with those receiving the conventional dose of MTX as monotherapy. No serious adverse events were reported during the entire study period in the two groups. CONCLUSIONS: Combination therapy using pulse AZA and low-dose MTX can be an efficacious treatment for moderate-to-severe plaque psoriasis, with a relatively good safety profile.

"If I die for touching him, let me die": a rapid ethnographic assessment of cultural practices and Ebola transmission in high-risk border regions of Tanzania.

BACKGROUND: Ebola Virus Disease (EVD) is a rare but contagious disease caused by Ebola Virus (EBOV). The first Ebola outbreaks were reported in the Democratic Republic of Congo (DRC) before subsequent reported cases in Western and East African countries, including Uganda, which borders Tanzania. Proximity to EVD-infected countries raises the prospect of cross-border transmission, raising alarm in Tanzania. This study aimed to explore the cultural practices likely to prevent or escalate EVD transmission in the event of its outbreak in the country. METHODS: This rapid ethnographic assessment employed observation, interviews, and focus group discussions to collect data from people with diverse characteristics in five regions of Tanzania Mainland namely, Kagera, Kigoma, Mwanza and Songwe regions and Zanzibar Island. The qualitative data was then subjected to thematic analysis. FINDINGS: Cultural practices may escalate the transmission of EVD and hinder its prevention and control. These cultural practices include caring sick people at home, confirmation of death, mourning, and body preparation for burial. Communal life, ceremonies, and social gatherings were other aspects observed to have the potential for compounding EVD transmission and hindering its containment in case of an outbreak. CONCLUSION: Cultural practices may escalate EVD transmission as identified in the study settings. As such, Risk Communication and Community Engagement (RCCE) activities should be interventionist in transforming cultural practices that may escalate the spread of EVD as part of preparedness, prevention, and control efforts in the event of an outbreak.

Comprehending the disruptive influence of workplace gaslighting behaviours and mobbing on nurses' career entrenchment: A multi-centre inquiry.

AIM: To explore the disruptive influence of workplace gaslighting behaviours and mobbing on nurses' career entrenchment across multiple healthcare centres. DESIGN: A multi-centre cross-sectional. METHODS: Data were collected from 483 nurses from various healthcare settings in Egypt, spanning from January 2024 to February 2024. The Gaslighting at Work Questionnaire, Luxembourg Workplace Mobbing Scale and Career Entrenchment Scale were employed for data collection. RESULTS: The study revealed moderate levels of gaslighting, mobbing and nurses' career entrenchment. Also, there is a negative correlation between nurses' career entrenchment and both gaslighting and mobbing, while gaslighting and mobbing exhibit a positive correlation. The study also highlighted regional disparities in the prevalence of these phenomena, with the highest incidences noted in urban healthcare settings. CONCLUSION: The findings underscore the critical impact of workplace gaslighting and mobbing on nurses' career entrenchment. REPORTING METHOD: The relevant reporting method has been adhered to, that is, STROBE. IMPLICATION FOR THE PROFESSION: The future of the nursing profession requires building productive nurses who can cope with negative workplace experiences. This could be achieved by cultivating a workplace culture that has zero tolerance for these experiences. Offering counselling services or employee assistance programmes to help nurses cope with the emotional toll of these negative experiences is a promising strategy. IMPACT: This study is the first to examine serious workplace practices like gaslighting and mobbing in a nursing context, emphasizing their effect on nursing-sensitive indicators like career entrenchment. It is one of the important initiatives geared towards upgrading the competitiveness and magnetism of healthcare organizations in the era of green human resources management. Results provide valuable insights for nurse leaders to control nursing turnover and shortage crises in different endeavours. PATIENT OR PUBLIC CONTRIBUTION: In our study, nurses from diverse geographical regions and varied specialties actively participate, offering a rich tapestry of experiences and perspectives.

The mediating role of cardiac patients' perception of nursing care on the relationship between kinesiophobia, anxiety and depression in rural hospitals: a cross-sectional study.

BACKGROUND: Kinesiophobia could act as a significant barrier against physical activity following cardiac procedures worsening cardiovascular health problems and potentially leading to conditions like hospital-acquired anxiety and depression among patients with cardiovascular disease (CVD). Nurses are the vanguard health care team who can aid patients in taking proactive steps to overcome fear of movement following cardiac procedures. AIM: The overarching aim is to investigate the relationship between kinesiophobia, anxiety and depression, and patients' perception of nursing care. METHOD: A descriptive correlational research design in two rural hospitals, conducted at cardiac intensive care units of Kafr Eldawar Hospital and Damanhur Medical National Institute. Data were collected from 265 nurses, using the following patient-reported outcome measures, the Tampa Scale for Kinesiophobia (TSK), the Hospital Anxiety and Depression Scale (HADS), the Person-Centered Critical Care Nursing Questionnaire (PCCNP) and the patients' demographic and clinical profile. RESULT: A significant negative correlation was found between HADS and PCCNP (r: -0.510, p < 0.001) however, Kinesiophobia was significantly and positively correlated (r: 0.271, p < 0.001). A direct effect of PCCNP in the presence of the mediator was found to be not statistically significant (-0.015, CR = 0.302, p = 0.763). Nonetheless, PCCNP indirectly affects kinesiophobia through HADS (p=-0.099). IMPLICATION FOR NURSING PRACTICE: Customizing individualized cardiac rehabilitation (CR) programs based on the emotional experience of cardiac patients will be conducive to rehabilitation and prognosis for patients, thereby lessening the physical burden and improving their quality of life.

The role of Empathy in the relationship between emotional support and caring behavior towards patients among intern nursing students.

BACKGROUND: The empathic relationship between nursing students and patients allows them to understand and address caring behavior for patients. Appropriate emotional support equips them to overcome the complexities and difficulties inherent in patient care. This support cultivates resilience and self-awareness, enabling students to manage their emotions effectively and establish meaningful connections and caring with their patients. OBJECTIVES: To investigate the role of empathy in the association between emotional support and caring behavior toward patients among intern nursing students at Alexandria and Damanhur University. SUBJECTS: The study subjects were 200 intern nursing students in their internship years of 2022-2023, randomly selected from an equal sample size from Alexandria and Damanhur University, Egypt. TOOLS: A questionnaire of social information& academics from students, the Toronto Empathy Questionnaire, the Caring Dimension Inventory, and the Multidimensional Scale of Perceived Social Support are used to collect participants' data. RESULTS: Empathy was associated with caring behavior and emotional support among nursing students (P < 0.001), and higher levels of empathy indicated increased levels of caring behavior and emotional support. The caring behavior significantly increased when intern nursing students received more emotional support and among those who were not working in private hospitals (p < 0.001,&p = 0.023 respectively). Empathy acts as a mediating role in the relationship between emotional support and caring behavior. IMPLICATIONS: Implementing strategies to assist interns in navigating challenges and promoting a culture of support can facilitate the cultivation of caring behaviors. Shedding light on the interconnectedness of empathy, emotional support, and caring behavior can inform the design of interventions to strengthen empathy as a pathway to improving patient outcomes. CONCLUSION: Empathy is a mediating factor in the relationship between emotional support and caring behavior. This suggests that interventions promoting empathy may serve as a pathway to enhancing caring behavior among nursing students and strategies for improving patient care outcomes by strengthening empathy skills among healthcare professionals.

Perceived stress, coping strategies, symptoms severity and function status among carpal tunnel syndrome patients: a nurse-led correlational Study.

BACKGROUND: Carpal tunnel syndrome (CTS) is a prevalent condition characterized by hand pain, tingling, and numbness. The severity of symptoms and functional status in CTS patients may be influenced by perceived stress and how individuals cope with it. However, scarce knowledge exists about the role of coping strategies as moderators in this relationship. Unfolding the role of perceived stress and coping strategies for CTS management will help the nurse to provide comprehensive and tailored nursing care. This will ultimately improve patient comfort, functionality, and quality of life. PURPOSES: This study aimed to examine the role of coping strategies (adaptive and maladaptive) in the relationship between perceived stress and both symptoms severity and function status among those patients. METHOD: We employed a multisite, correlational study design with moderation analysis. The study included 215 patients with CTS from neurosurgery outpatient clinics at three hospitals in Egypt. After obtaining their consent to participate, eligible participants completed anonymous, self-reported measures of perceived stress, the brief COPE inventory, and the Boston Carpal Tunnel Questionnaire. Demographic and biomedical data were also collected. The questionnaire took about 20 min to be completed. The data was collected over six months, starting in February 2023. RESULTS: The results showed that perceived stress, adaptive coping, and maladaptive coping were significant predictors of symptoms severity and functional status. Adaptive coping moderated the relationships between perceived stress and both symptoms severity and function status, while maladaptive coping did not. The interaction between perceived stress and adaptive coping explained a moderate effect on symptoms severity and function status after controlling for the main effects and the covariates. CONCLUSION: This study explored the relationship between perceived stress, coping strategies, and outcomes in patients with CTS. The results indicate that nurses play a vital role in assessing and assisting patients to adopt effective coping strategies to manage perceived stress and alleviate symptoms and functional impairment. Moreover, the findings support the need for psychological interventions that address both perceived stress and coping strategies as a way to enhance the functioning status and quality of life of patients with CTS.

Hooked on technology: examining the co-occurrence of nomophobia and impulsive sensation seeking among nursing students.

BACKGROUND: Nomophobia, the crippling fear of being disconnected from mobile devices, is a burgeoning global concern. Given the critical nature of the profession of nursing students, understanding nomophobia's prevalence and potential impacts on patient care and professional conductors becomes even more crucial. AIM: This study explores the relationship between nomophobia and impulsive sensation-seeking among nursing students in Egypt. DESIGN AND METHODS: A multicenter cross-sectional survey was conducted with 1626 nursing students randomly selected from three universities across Egypt. TOOLS: The Arabic versions of the Nomophobia and Impulsive Sensation Seeking Questionnaires were employed to gather data. RESULTS: Our findings revealed that 40.3% of the surveyed nursing students exhibited severe nomophobia, indicating a substantial dependence on their mobile devices. Notably, this high prevalence was accompanied by a strong tendency towards impulsive sensation-seeking behaviors. Furthermore, a stepwise regression analysis identified several significant predictors of nomophobia (p < 0.001). Impulsive sensation-seeking, year of study, average daily smartphone usage, and age emerged as key factors, explaining 27.5% of the variability in nomophobia scores. CONCLUSION: The prevalence of nomophobia among Egyptian nursing students is undeniable, highlighting their substantial reliance on mobile devices. A significant association with impulsive sensation-seeking behavior further compounds this dependence. Factors such as impulsive sensation seeking, year of study, average daily smartphone usage, and age were identified as significant predictors of nomophobia. Recognizing these factors as key predictors of nomophobia is crucial for designing effective interventions and psychotherapies. Prioritizing such interventions can promote future nurses' well-being and ensure they deliver the highest quality care to their patients.

Climate anxiety, environmental attitude, and job engagement among nursing university colleagues: a multicenter descriptive study.

BACKGROUND: Climate change, a pervasive global phenomenon, exerts discernible impacts on the physical, social, and psychological dimensions of well-being. The apprehension surrounding this complex environmental issue has reached a critical juncture, with over 76,000 individuals across more than thirty nations expressing profound levels of concern, characterizing their anxiety as either "very" or "extremely" pronounced. This surge in awareness regarding the potential consequences of climate change has given rise to an emergent and escalating challenge known as climate anxiety. This distinctive form of anxiety manifests through profound feelings of fear, helplessness, and despair elicited by the impending repercussions of climate change. Notably, the intersection of climate anxiety with occupational domains, particularly within the context of Nursing University Colleagues, suggests a nuanced relationship with job engagement, wherein the psychological responses to climate change may influence professional commitment and involvement. AIM OF THE STUDY: To examine the correlation among Climate Anxiety, Environmental Attitude, and Job Engagement among Nursing University Colleagues comprising eight distinct nursing faculties. DESIGN: A multicenter descriptive, cross-sectional research design study followed. SUBJECT: Three hundred fifty-nine participants from the Centre, Delta, West, Suez Canal, and Upper regions of Egypt using a stratified random cluster sampling technique. MEASUREMENTS: Social and health related to climate data structured questionnaire, climate anxiety scale, environmental attitude inventory, and job engagement scale. RESULTS: The influence of demographics on climate anxiety, environmental attitude, and job involvement was not observed. Nevertheless, geographical variations emerged as a noteworthy factor. A statistically significant inverse correlation was identified between climate anxiety, job engagement dimensions, and the overall score of environmental attitudes. CONCLUSION: Climate anxiety was strongly associated with environmental attitudes and job engagement among nursing university colleagues. Higher climate anxiety is associated with a lower attitude towards the environment and decreased job engagement. Additionally, a higher attitude towards the environment is associated with decreased overall engagement in participants' jobs. IMPLICATIONS: The study's patterns make it clear how important it is to provide targeted psycho-educational interventions to help reduce climate anxiety among the group of nursing university colleagues. The imperative lies not only in alleviating the immediate psychological distress associated with heightened climate anxiety but also in fostering adaptive coping mechanisms. By doing so, these interventions serve as instrumental tools in nurturing resilience, thereby fortifying the mental well-being of nursing professionals amidst the evolving landscape of climate-related concerns.

Exploring the mediating influence of acceptance of change: A study on gerontechnology acceptance, mental well-being, and urban-rural disparities among older adults.

BACKGROUND: The global aging population necessitates leveraging technology for older adults' independence and mental well-being. Gerontechnology, tailored for older users, thrives when accessible and accepted, with the pivotal role of acceptance of change shaping its adoption. AIMS: This study investigates the mediating role of acceptance of change in the relationship between gerontechnology acceptance and mental well-being among older adults and explores disparities in urban and rural settings DESIGN & METHODS: A cross-sectional, correlational design adhering to STROBE guidelines collected data through an interview survey from 802 older adults. Instruments included the Older Adult Structured Survey, Short Version of Senior Technology Acceptance, Acceptance of Change Scale, and the World Health Organization Well-Being Index. RESULTS: The results underscore a significant correlation between technology adoption, adaptability, and mental well-being among 60-year-olds and older. Notably, an individual's openness to change significantly influences the technology-mental well-being relationship, emphasizing its impact on overall health. Urban areas exhibit a stronger positive correlation between technology acceptance and mental well-being, whereas rural regions demonstrate a more pronounced negative correlation. CONCLUSION: This research contributes valuable knowledge for addressing the unique challenges older adults face in diverse geographic settings, paving the way for targeted and effective initiatives. IMPLICATIONS: Nurses should prioritize understanding the nexus between gerontechnology acceptance, change adaptability, and mental wellness, integrating technology education and culturally sensitive interventions to enhance care strategies for older adults in diverse geographic settings. This study lays the groundwork for developing person-centered geriatric nursing care plans, underscoring the importance of harnessing technology for improved mental well-being.

Assessment of antimicrobial activity and GC-MS using culture filtrate of local marine Bacillus strains.

Secondary metabolites produced by Bacillus species from marine sources encompass a variety of compounds such as lipopeptides, isocoumarins, polyketides, macrolactones, polypeptides and fatty acids. These bioactive substances exhibit various biological activities, including antibiotic, antifungal, antiviral, and antitumor properties. This study aimed to isolate and identify a particular species of Bacillus from marine water and organisms that can produce bioactive secondary metabolites. Among the 73 Bacillus isolates collected, only 5 exhibited antagonistic activity against various viral and bacterial pathogens. The active isolates were subjected to 16S rRNA sequencing to determine their taxonomical affiliation. Among them, Bacillus tequilensis CCASU-2024-66 strain no. 42, with the accession number ON 054302 in GenBank, exhibited the highest inhibitory potential. It displayed an inhibition zone of 21 mm against Bacillus cereus while showing a minimum zone of inhibition of 9 mm against Escherichia coli and gave different inhibition against pathogenic fungi, the highest inhibition zone 15 mm against Candida albicans but the lowest inhibition zone 10 mm was against Botrytis cinerea, Fusarium oxysporum. Furthermore, it demonstrated the highest percentage of virucidal effect against the Newcastle virus and influenza virus, with rates of 98.6% and 98.1%, respectively. Furthermore, GC-MS analysis was employed to examine the bioactive substance components, specifically focusing on volatile and polysaccharide compounds. Based on these results, Bacillus tequilensis strain 42 may have the potential to be employed as an antiviral agent in poultry cultures to combat Newcastle and influenza, two extremely destructive viruses, thus reducing economic losses in the poultry production sector. Bacteria can be harnessed for the purpose of preserving food and controlling pathogenic fungi in both human and plant environments. Molecular docking for the three highly active derivatives 2,3-Butanediol, 2TMS, D-Xylopyranose, 4TMS, and Glucofuranoside, methyl 2,3,5,6-tetrakis-O-(trimethylsilyl) was carried out against the active sites of Bacillus cereus, Listeria monocytogenes, Candida albicans, Newcastle virus and influenza virus. The data obtained from molecular docking is highly correlated with that obtained from biology. Moreover, these highly active compounds exhibited excellent proposed ADMET profile.

Effect of Thermo-mechanical Cycling on Fracture Resistance of Different CAD/CAM Crowns: An In Vitro Study.

AIM: To evaluate the effect of thermo-mechanical cycling (TMC) on fracture resistance of different computer-aided design/computer-aided manufacture (CAD/CAM) crowns. MATERIALS AND METHODS: A total of 42 CAD/CAM crowns were fabricated on epoxy resin maxillary first premolar teeth and divided into three groups (n = 14) according to the material used: IPS e.max CAD (Ivoclar Vivadent) lithium disilicate (LD), Vita ENAMIC (VE) (VITA Zahnfabrik), Tetric CAD (Ivoclar Vivadent). Also, each group was subdivided into two equal subgroups according to TMC (n = 7). Subgroups (O) without TMC and subgroup (W) with TMC (5-55°C, 30 second, 75,000 cycles). All samples in each group were cemented with a universal bond (Tetric N bond universal) and adhesive resin cement (Variolink Esthetic DC) (Ivoclar Vivadent). Subsequently, the samples were loaded to failure in a universal testing machine at a crosshead speed of 1 mm/min, and the fracture pattern and the fracture resistance in each group were recorded. RESULTS: Fracture resistance was analyzed by one-way analysis of variance (ANOVA) test, followed by Tukey's post hoc test for pairwise comparison. Fracture resistance showed a significant difference between the tested groups before and after TMC; IPS e.max CAD has the highest value (1233.35 ± 97.72, 1165.73 ± 199.54 N) followed by Tetric CAD (927.62 ± 42.5, 992.04 ± 53.46 N) and Vita ENAMIC has lowest value (506.49 ± 74.24, 354.69 ± 90.36 N). CONCLUSION: Thermo-mechanical cycling affected the fracture resistance of both polymer-based CAD/CAM crowns. CLINICAL SIGNIFICANCE: For dental practitioners, both IPS e.max CAD and Tetric CAD can be used clinically for posterior teeth, providing satisfactory results and resistance to fracture.

Compassion fatigue and stress related to cardiopulmonary resuscitation: a study of critical care nurses' experiences.

BACKGROUND: Cardiopulmonary resuscitation (CPR) is considered one of the most stressful experiences in critical care nursing; it directly and indirectly leads to compassion fatigue and burnout. AIM: Determine the levels of and relationship between postcode stress and compassion fatigue. DESIGN AND METHODS: A descriptive-correlational study using 300 critical care nurses from five intensive care units in two hospitals was conducted. TOOLS: Demographic and work-related data, the Postcode Stress Scale, and the Professional Quality of Life Scale: Compassion Fatigue subscale. RESULTS: Nurses had moderate to high postcode stress and compassion fatigue (67.98 ± 16.39 and 65.40±14.34, respectively). Moreover, there was a significant positive correlation between postcode stress, burnout (r=0.350, p=<0.001), secondary traumatic stress (r=0.518, p=<0.001), and subsequently, compassion fatigue (r=0.449, p=<0.001). In addition, higher levels of postcode stress were associated with higher levels of compassion fatigue with its subscales: burnout and secondary traumatic stress, with a coefficient of determination for compassion fatigue (0.199), burnout subscale (0.121), and secondary traumatic stress (0.266). CONCLUSION: Critical care nurses involved in resuscitation experiences are susceptible to postcode stress, burnout, secondary traumatic stress, and compassion fatigue. There is a significant relationship between these factors, with higher levels of postcode stress contributing to higher levels of compassion fatigue and its subscales: burnout and secondary traumatic stress. These results highlight the importance of addressing and managing the psychological well-being of nurses in resuscitation settings to mitigate the adverse effects of stress and promote their overall resilience and well-being.

Protective Effects of Propolis and Chitosan Nanoparticles against Ibuprofen-Induced Hepatotoxicity in Albino Rats.

Post-marketing hepatotoxicity findings are more common or occur much later. NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen are consumed in large quantities around the world. NSAIDs have a low incidence of hepatotoxicity but their wide use makes them a major contributor to drug-induced liver injury. Hepatitis is linked to systemic oxidative stress which results in cellular necrosis and fibrosis, as well as tissue lipoprotein peroxidation and glutathione depletion. Given the lack of safe and effective anti-hepatitis drugs in medicine today, natural substances appear to be a promising and safe alternative. Propolis and chitosan are considered natural substances that have a protective effect on the hepatocytes. The purpose of this study was to validate the protective effect of propolis/chitosan nanoparticle extracts on ibuprofen-induced hepatotoxicity. Thirty (30) albino rats were used for the experiment. Animals were exposed to ibuprofen (400 mg/kg body weight/day) for 4 weeks (7 days/week) followed by treatment with propolis (200 mg/kg body weight/day) and chitosan extract (200 mg/kg body weight/day) separately and also in combination for consecutive 4 weeks. This study revealed a significant increase in serum transaminases, alkaline phosphatase, albumin, and total bilirubin in serum, as well as an increase in lipid peroxidation (MDA) and nitric oxide (NO). Furthermore, GSH, GST, and SOD decreased significantly in the group that was exposed to ibuprofen. Furthermore, there was a significant increase in pro-inflammatory parameters such as IL-1ß and NF-ĸB, as well as low levels of anti-inflammatory parameters such as IL-6 and BCl-2. These alterations were improved by propolis and chitosan extracts, which was further confirmed in experimental animals. This study demonstrated that propolis and chitosan nanoparticle extracts have the potential to protect against hepatotoxicity induced by ibuprofen, due to their ability to regulate anti-inflammatory and anti-oxidative defense activities.

Optimized Ultraviolet-C Processing Inactivates Pathogenic and Spoilage-Associated Bacteria while Preserving Bioactive Proteins, Vitamins, and Lipids in Human Milk.

Holder pasteurization (HoP) enhances donor human milk microbiological safety but damages many bioactive milk proteins. Though ultraviolet-C irradiation (UV-C) can enhance safety while better preserving some milk proteins, it has not been optimized for dose or effect on a larger array of bioactive proteins. We determined the minimal UV-C parameters that provide >5-log reductions of relevant bacteria in human milk and how these treatments affect an array of bioactive proteins, vitamin E, and lipid oxidation. Treatment at 6000 and 12 000 J/L of UV-C resulted in >5-log reductions of all vegetative bacteria and bacterial spores, respectively. Both dosages improved retention of immunoglobulin A (IgA), IgG, IgM, lactoferrin, cathepsin D, and elastase and activities of bile-salt-stimulated lipase and lysozyme compared with HoP. These UV-C doses caused minor reductions in α-tocopherol but not γ-tocopherol and no increases in lipid oxidation products. UV-C treatment is a promising approach for donor human milk processing.

Effect of Different Primers on the Shear Bond Strength of Orthodontic Brackets Bonded to Reinforced Polyetheretherketone (PEEK) Substrate.

This in vitro study assessed the effect of different primers on the shear bond strength (SBS) and adhesive remnant index (ARI) of orthodontic brackets bonded to reinforced polyetheretherketone (PEEK) substrate. A total of 40 specimens were randomly distributed to two groups based on the primer used for orthodontic bonding: group 1 (control)-Transbond XT adhesive with Visio.link primer and group 2 (test)-orthodontic adhesive (Transbond XT) with traditional orthodontic primer. After bonding, specimens were thermocycled followed by SBS testing and ARI scoring of debonded specimens. Data were analyzed using the unpaired independent t-test and the Chi-square test. Group 1 specimens showed significantly higher SBS values (21.38 ± 1.48 MPa) compared to group 2 specimens (18.63 ± 1.29 MPa) (p < 0.0001). Adhesive remnant index scores showed no significant variations in bond failure modes and distributions between groups. The SBS obtained by the tested primers exceeded the clinically recommended value. Consequently, there is a comparable clinical application for both tested primers in orthodontic bonding, especially the traditional orthodontic primer, where the availability of Visio.link in clinical practice is not ensured.

Epidemiological characteristics, etiological spectrum, and outcomes of adult patients with pericardial effusion at a Teaching Hospital in Somalia.

Background: Pericardial effusion (PE) is an abnormal fluid volume in the pericardial space and is a common clinical entity. The incidence of PE is estimated diversely and depends on risk factors, etiologies, and geographic locations. Objectives: This study aimed to assess the clinical characteristics, etiologic spectrum, echocardiographic features, and outcomes among patients with different types of PE. Method: This retrospective observational study included 93 patients with confirmed PE. Their medical records were reviewed in the hospital information system of Mogadishu Somali Turkish Training and Research Hospital between April 2022 and September 2022. Patient demographics, clinical characteristics, chest X-rays, echocardiography, laboratory findings, management approaches, and outcome reports were reviewed and recorded. Results: Out of the 3000 participants, 3.1% (n = 93/3000) met the definition of definitive PE. In this study, we included 51 females and 42 males. Among the patients, 86% (n = 80) had at least one comorbidity, with diabetes (38.7%) and hypertension (37.6%) being the most common. The most frequently reported clinical presentation findings were shortness of breath (67.7%), chest pain (49.4%), cough (47.3%), and palpitations (47.3%). Cardiac tamponade developed in 9.7% (n = 9) of the patients. Pericardial taps were performed in 64.5% of the cases. Our analysis showed that the most common cause of PE was cardiac disease (n = 33, 35.4%), followed by tuberculosis (TB) (n = 25, 26.8%), uremic pericarditis (n = 24, 25.8%), and hypothyroidism (n = 10, 10.7%). Regarding the severity of PE based on echocardiographic findings, nearly half of the patients (n = 46, 49.4%) had mild PE, whereas 26.8% (n = 25) had moderate PE, and 23.6% (n = 22) had severe PE. Two-thirds of the cases (66.6%) were managed with furosemide, 48 (51.6%) patients were treated with an anti-inflammatory, hemodialysis was performed in 24 (25.8%) patients and antituberculous medications were administered to 7 (7.5%) patients. Out of the 93 patients, 24 (25.8%) died during the hospital stay. It was determined that the mortality risk of patients with renal failure was 7.518 times higher than those without (p = 0.004), and the risk for those with TB was 5.554 times higher than those without (p = 0.011). Other variables were not influential on mortality (p > 0.050). Conclusion: Our study results demonstrate the epidemiological profile of PE in Somalia. The leading causes of PE were cardiac diseases, uremic pericarditis, TB, and hypothyroidism. PE is a significant cause of morbidity and mortality in Somalia, especially in individuals with renal failure and TB infection.

'Health Camp' model: a unique approach for child vaccination in non-state armed actor controlled, inaccessible geographies in Somalia.

Decades of conflict, political instability, and limited infrastructure left Somalia facing significant challenges to offer consistent and equitable health services, especially for child vaccination. Recent data reveals alarming vaccination gaps, with 60% of children receiving no vaccinations, and only 11% completing required vaccines. Despite global support, an estimated 1.15 million children remain unvaccinated, half of them reside in inaccessible areas controlled by non-state armed actors. In this context, the Far-Reaching Integrated Delivery (FARID) project was initiated since October 2022 across 10 districts of Galmudug and Hirshabelle state in Somalia. Employing the 'Health Camp' model, FARID addresses social, structural, and gender barriers, adapting to ever-changing context of inaccessible regions by providing mobile health facilities and outreach health and nutrition services, including child vaccination. This approach effectively reached previously unreached population in Somalia's most difficult-to-reach areas. Implemented in phases, the project immunized 51,168 children (0-23 months) who had not received any prior vaccinations (23,753 boys and 27,415 girls), screened and treated 14,158 malnourished children (0-59 months) and vaccinated 11,672 pregnant women during March-December 2023. The project's success hinges on intensive community engagement, local partnerships, innovation in mapping and data management, and delivery of integrated services tailored to population needs. The project underscores the critical role of local community-based organizations and clan elders in reaching inaccessible populations through humanitarian negotiation amidst security challenges. The project has achieved significant milestones aligned with national health strategic plans, including progress towards universal health coverage and improved immunization access in Somalia's most challenging regions.

Main findings To improve immunization coverage in areas with access constraints, programs must be integrated, utilize innovation in data systems and mapping and have deep knowledge of humanitarian access negotiation techniques and principles.Added knowledge Rights-based approaches including participation, empowerment and accountability are key for a successful immunization program for equitable access.Global health impact for policy and action The strengthening of human rights for health through inclusion of populations living under non-state actors' control in national health policies and legal frameworks is key for equitable access to vaccination to prevent and stop mortalities and morbidities caused by outbreaks and pandemics.

Combined low-dose isotretinoin and long-pulsed nd: YAG laser in the treatment of post-acne erythema.

Post-acne erythema (PAE) is a bothering skin condition that emerges from inflammatory acne and persists after its resolution. It is characterized by telangiectasia and erythematous macules. the role of 1064-nm Nd: YAG when combined with low-dose isotretinoin in the acne erythema treatment. forty-eight PAE patients were involved in the study. They were divided into two groups; group (A) patients administering a low dose of oral isotretinoin (10 mg/day) and underwent a total of six two-week interval sessions of 1064 ND-YAG laser treatment, group (B) patients administering a low dose of oral isotretinoin (10 mg/day) only. All adverse effects experienced during the course of therapy were documented, and photos were taken before the start of the treatment and following the end of the treatment duration. Following the completion of the therapeutic intervention, a significant improvement in clinical condition was observed in both groups, with more improvement in group (A) compared to group (B) as evidenced by a notable improvement in the score on the Clinician Erythema Assessment Scale (CEAS) and also a significant decrease in the mean value of optical density of the erythema. combined 1064-nm Nd: YAG with low-dose isotretinoin may be an efficient and secure line in the PAE treatment. Also, the combined therapy had superior results when compared to low-dose isotretinoin alone.
