Objective: to determine the incidence of HBV and HCV in pediatric ward. Sitting: 2ed March teaching hospital, sebha Libya. Materials and Methods: this was a prospective hospital base study of pediatric cases admitted to 2ed March teaching hospital during a period from March 2018 to February 2019. Pediatric cases were studied for the incidence of HBsAg and HCV Ab by ELISA, Rapid technique. The positive result was confirmed with line immuno-assay. Results: the study showed positive HBsAg in 12 patients and HCV in 2 cases out 25 cases represented with acute hepatitis from a total of 1763 pediatric cases were submitted in this study, with incidence rate of 0.68% and 0.11% respectively. Conclusion: the incidence of HBV and HCV are low in Sebha, therefore active program need to be applied to control the spread of infection among the population.

It is difficult to predict how the founder of psychoanalysis, Sigmund Freud, would react to an attempt to link his theory and the method of treating mental disorders based on it [1], with such a purely physical disease as acute pneumonia (AP). It is unlikely that such an innovation could cause full approval and support. However, in this context, we are not talking about psychoanalysis as a therapeutic method for AP. In this case, only the diagnostic features of this technique are of interest

Systemic lupus erythematosus (SLE) is a chronic inflammatory multisystem disorder that commonly affects females during their reproductive years. It is characterized by the presence of autoantibodies and immune complex deposition, the etiology is not known but the interaction of an environmental agent in a genetically susceptible individual is thought to be fundamental. SLE most frequently involves the skin, joints, lungs, heart, kidney, and neuropsychiatric manifestations that may occur during the course of the disease. Mood disorders among SLE patients, particularly depression, are common and important psychiatric manifestations of the disease, in addition to their high incidence and possible deleterious influence on disease progression, so early identification and treatment of depression may have a significant influence on the patient’s quality of life.

Background: Early childhood caries may develop as soon as teeth erupt. Promoting oral health care programs is very important and helps to reduce dental caries in young children. The aim of this study was to assess the infant/child oral health (IOH) related knowledge, attitudes, and practices (KAP) of parents in Riyadh, Saudi Arabia. Materials and Methods: A cross-sectional descriptive study was conducted among 327 parents. Visiting the family medicine center at prince sultan military medical city, Riyadh Saudi Arabia. A 39-item questionnaire covering socio-demographic characteristics and questions pertaining to KAP regarding OH care will be used to collect the data. Descriptive statistics, Student’s t-test, one-way analysis of variance, and Scheffe’s test will use for the statistical analysis (p ≤ 0.05). Results: The result showed that the majority of the parents had good knowledge regarding OH, knowledge of cleaning (92.4.%), and knowledge of the amount of sugar (88.1.%). the parent’s age group (30 to 39) years (n =147) reported the highest mean (knowledge, attitudes, and practice) scores among all other age groups with a knowledge mean score of (6.80 ± 1.73), an attitude mean score of (8.86 ± 1.37), and a practice mean score of (5.14 ± 1.86).  Female parents showed significantly higher mean knowledge, attitude, and practice scores than male parents. In addition, the middle-income level parents’ group (n = 295) reported higher knowledge mean score compared to the low-income parents’ group (n = 15) with a mean difference of d = 1.15, p = .041.  Conclusion: Parents’ knowledge about maintaining oral and dental health care for infants/children was inadequate. Essentially, medical professionals are the initial ones to interact with expecting and new moms. Therefore, need to raise parents’ awareness about oral and dental health for infants/children, through the development and implementation of long-term education and promotions programs.

Background: Pediatric nurses are in a unique position to provide oral health care to hospitalized children and help in the prevention and management of oral diseases. The objectives of this study were to determine pediatric nurses’ level of oral health knowledge and to evaluate their attitude towards the prevention of oral diseases and willingness to obtain more oral health education and training.Methods: A cross-sectional study was conducted at 6 randomly selected hospitals in Riyadh city, Saudi Arabia. A self-administrated questionnaire with items including demographic data, dental knowledge, attitude, and willingness to obtain more information and training was completed by 240 pediatric nurses working in different pediatric medical wards.Results: On average, 64% of surveyed pediatric nurses had acceptable dental knowledge. Only 79% of nurses assess patients’ mouths on admission. About 77% of nurses claimed to receive instructions regarding oral care before qualification and 72% after qualification. However, 91% showed great attitudes and interest in providing oral care to hospitalized children and were willing to obtain more information about oral health care for children.Conclusion: Pediatric nurses working in Riyadh hospitals had limited oral health knowledge, however, they showed good awareness and a positive attitude toward promoting oral health care to hospitalized children.

Background: Nicotinamide adenine dinucleotide (NAD⁺) is a pivotal coenzyme and signaling substrate that integrates redox balance with mitochondrial energy production, DNA repair, epigenetic control, and cellular stress resilience. Declines in NAD⁺ availability—frequently observed with ageing, chronic inflammation, and metabolic stress—have intensified interest in NAD⁺ restoration as a potential strategy to influence disease biology across multiple organ systems.Objective: This narrative review summarizes contemporary mechanistic and translational evidence on NAD⁺ biosynthesis and turnover, highlighting the de novo kynurenine pathway and vitamin B3–dependent salvage routes (nicotinic acid, nicotinamide, nicotinamide riboside, and nicotinamide mononucleotide). We also examine how major NAD⁺ consumers and sensors, sirtuins, poly(ADP-ribose) polymerases (PARPs), and CD38 link NAD⁺ status to inflammation, oxidative stress, and tissue dysfunction in diverse clinical contexts.Methods: Peer-reviewed literature on NAD⁺ metabolism, NAD⁺-dependent signaling, and preclinical/clinical studies of NAD⁺ precursors was evaluated and organized into: (i) core biochemical functions in cellular energetics, (ii) NAD⁺ consumption in genome maintenance and immune signaling, and (iii) organ-focused evidence relevant to skin disorders, infertility and reproductive health, osteoarthritis, hearing loss, vision decline, gut barrier dysfunction, cardiovascular and renal metabolism, hepatic steatosis, neurological diseases, and skeletal muscle health.Results: NAD⁺ supports glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation, while acting as an essential substrate for PARP-driven DNA repair and sirtuin-mediated deacylation programs that shape mitochondrial fitness, inflammatory tone, and metabolic flexibility. Across experimental models, impaired NAD⁺ homeostasis repeatedly associates with mitochondrial dysfunction, heightened oxidative injury, and dysregulated immune–barrier responses, features shared by intestinal inflammation, neurodegeneration and ischemic injury, cardiometabolic disease, kidney injury, and fatty liver disease. Supplementation with NAD⁺ precursors (notably NR and NMN) reliably elevates NAD⁺ in preclinical systems and increases circulating NAD⁺ metabolites in humans, with early signals of pathway engagement; however, clinical outcomes remain heterogeneous across populations, dosing regimens, and endpoints. Evidence for intravenous NAD⁺ “drip” therapy is comparatively limited and insufficiently standardized, with constraints related to tolerability, dose consistency, and cost, underscoring the need for controlled trials.Conclusion: NAD⁺ occupies a central position at the interface of energy metabolism, genome integrity, and immunometabolic signaling, providing a coherent framework for understanding how cellular stress can propagate multisystem dysfunction. Although NAD⁺-boosting strategies are biologically plausible and mechanistically supported, definitive clinical benefit across skin, fertility, osteoarthritis, sensory decline, gut disorders, cardiovascular and hepatic disease, neurological conditions, and muscle health will require well-designed human studies with standardized biomarkers, safety surveillance, and clinically meaningful endpoints.

The clinical phenotypes in 268 JAK2V617F mutated MPN patients in the Seoul study were PV in 101, ET in 95 and MF in 78 and 56 CALR mutated MPN consisted of PV in none, ET in 40 and MF in 16 cases. CALR mutated MPN patients were younger than JAK2V617F mutated MPN patients (mean ages 57.5 and 66 years), had lower values for values for leukocytes (8.6 vs 11.9x109/L) and higher values for platelets (898 vs 643x109/L respectively). Bone marrow histopathology in 268 JAK2V617F mutated MPN patients in the Seoul study was featured by an increased erythropoiesis and megakaryopoiesis (EM) in 13.5%, an increased erythropoiesis, megakaryopoiesis and granulopoiesis (EMG) in 31.3%, a normocellular megakaryocytic (M) proliferation in 29,1%, a megakaryocytic and granulocytic (MG) proliferation with a relative reduction of erythropoiesis in post-ET and Post-PV myelofibrosis in 26.2%. The bone marrow histology in 56 cases of CALR mutated MPN show a predominantly increased megakaryopoiesis (M) in two thirds and an increased megakaryopoiesis and granulopoiesis (MG) with a decreased erythropoiesis in one third. Thirteen consecutive CALR MPN patients in the Belgian & Dutch cross sectional study presented with thrombocythemia associated with a typical PMGM bone marrow histology in 11 and myelofibrosis in 2 cases. All 11 thrombocythemia and 2 myelofibrosis CALR mutated MPN patients did not have constitutional symptoms and did not suffer from microvascular erythromelalgic disturbances, major thrombosis at platelet counts between 400 and 1000x109/L. There was an occurrence of hemorrhages at platelet counts above 1000x109/L in two CALR thrombocythemia cases. Bone marrow histology of CALR mutated thrombocythemia in the Seoul and Belgian/Dutch study showed loose clusters of large megakaryocytes (M) with bulky, cloud-like nuclei with a normal or a minor reduction of erythropoiesis and no increase in reticulin fibers grade 0 or 1 (RF 0 or 1). CALR thrombocythemia patients show various degrees of increased bone marrow cellularity due to dual megakaryocytic and granulocytic (MG) proliferation featured by large megakaryocytes with roundish bulky nuclear forms and cloud-like clumsy nuclei, which are almost never seen in JAK2V617F ET and PV. Assessment of allele burden is an independent and most important factor for all molecular variants MPN disease burden. Overt myelofibrosis with advanced post PV and or ET myelofibrosis at the bone marrow level occurred in one third (30%) of 208 evaluable JAK2 MPN patients and in 8 (14%) of 56 CALR MPN patients in the Seoul study.

The purpose of this study is to highlight the drug abuse hazards and preventive aspects. From a public health perspective, substance abuse has long been a source of major concern, both for the individual’s health and for wider society as a whole. The UK has the highest rates of recorded illegal drug misuse in the western world. In particular, it has comparatively high rates of heroin and crack cocaine use. Substances that are considered harmful are strictly regulated according to a classification system that takes into account the harms and risks of taking each drug. The adverse effects of drug abuse can be thought of in three parts that together determine the overall harm in taking it. Some addictive substances are more damaging to the skeletal system along with the others. In this review article, an effort has been taken to elaborate the effects of addictive drugs on human highlighting these most problematic substances for bones and also the promising potential prevention aspects of drug abuse.

Fascioliasis is a one of the most important serious parasitic zoonotic disease which caused by trematode giant liver fluke Fasciola hepatica and F. gigantica among cattle’s and humans. The infection of Fasciola can be control by the use of phytochemicals as anthelmintic components. The anthelmintic activities of dried root powder of medicinal plant Potentilla fulgens and their different preparations (organic extracts and column purified fraction) are uses in vitro against liver fluke F. gigantica. The dried root powder, different organic extract, and column fractions were time and concentration-dependent. Among all the organic extracts, ethanol extract was high toxic than other organic extracts. The toxic effect of ethanolic extract of P. fulgens after 2h exposure the LC50 value is 5.22 mg/ml against F. gigantica. The column purified fraction of dried root powder of P. fulgens shows more toxicity. The 2h LC50 of column purified fraction was 3.25 mg/ml whereas in 8h exposure the LC50 is 1.24 mg/ml. The phytochemicals of the P. fulgens may be used as anthelmintic components against liver fluke F. gigantica. 

Purpose: The role of healthcare workers in cervical cancer prevention is pivotal because healthcare workers’ recommendations have been reported to be a key motivational factor for cervical cancer screening among women in Nigeria. Assessing their knowledge, attitudes, and practices on cervical cancer prevention is necessary.Patients and methods: This is a cross-sectional survey involving healthcare workers in Ekiti State, Nigeria. A questionnaire designed for the study was used to obtain data about the knowledge, attitudes, and practices of the healthcare workers. Logistic regression was used to assess the determinants of practice and a p - value of less than 0.05 was taken as statistically significant.Results: Out of 188 participants that completed the study, 165(90.7%) had good knowledge about the prevention of cervical cancer while 24(13.2%) had good practice concerning the prevention of cervical cancer. positive attitude (Odds ratio 1.24, 95% CI 1.14 - 1.35, p < 0.001) increased the odds of good practice.Conclusion: There was no association between the knowledge of cervical cancer prevention and the practice of the healthcare workers. Further research is required to explore the incongruence between knowledge and practice of cervical cancer prevention and its practice.
