Alignment of the alveolar segments with early nasal cartilage tackling is the foundation upon which excellent surgical results are dependent. The purpose is to evaluate the short-term effect of triple combination of passive alveolar molding with early nasal molding augmented by controlled corrective power of lip tapping in lately presented moderate to severe unilateral complete cleft lip and palate infants. A prospective case series study was conducted in Plastic and Maxillofacial Surgery Department, Ain Shams University in collaboration with Orthodontics Department, from January 2021 till June 2023, 15 infants elder than 2 months till 6 months were enrolled in the study.

Background: Calcified nodules are associated with suboptimal preparation before stenting due to challenging crossing and unsuccessful pre-dilation and calcium cracking with conventional balloons. In this scenario, we report the use of shockwave intravascular lithotripsy for the successful lesion preparation of an undilatable and challenging calcified nodule in a patient presenting with ACS.

Case Summary: We report a case of a 79-year-old male patient presented with non-ST elevation myocardial infarction.

The liver has a distinctive capacity to regenerate, yet severe acute injury can be life-threatening if not treated appropriately. Inflammation and oxidative stress are central processes implicated in the pathophysiology of acute livery injury. NOX isoforms are important enzymes for ROS generation, NF-κB and NLRP3 activation, its inhibition could be vital in alleviating acute liver injury (ALI).

Synthetic single-chain bolalipids (SSCBs) are novel excipients in drug delivery, with potential as stabilizers or solubilizers. However, their impact on skin barrier function has not been comprehensively studied. Therefore, two SSCBs (PC-C24-PC and PC-C32-PC) were studied in aqueous systems for their impact on penetration of a model permeant into porcine skin.

Background: In the last three decades, much effort has been invested in measuring and improving the quality of diabetes care. We assessed the association between adherence to diabetes quality indicators and all-cause mortality in the primary care setting.

Methods: A nationwide, population-based, historical cohort study of all people aged 45-80 with pharmacologically-treated diabetes in 2005 (n = 222,235).

Guided by the molecular hybridization principle, a novel series of 4-chloropyridazinoxyphenyl conjugates (3a-h, 4a-e, and 5) was designed and synthesized as proposed apoptotic inducers and PARP-1 inhibitors. The growth inhibition % of the designed hybrids was investigated in eleven cancer cell lines, where the anticancer activities were found to be in the following order: 4-chloropyridazinoxyphenyl-aromatic ketones hybrids (3a-h) > 4-chloropyridazinoxyphenyl-benzyloxyphenylethan-1-one hybrids (4a-e) > 4-chloropyridazinoxyphenyl-thiazolidine-2,4-dione hybrid (5). Further, the most sensitive three cancer cell lines (HNO97, FaDu, and MDA-MB-468) were selected to measure the IC values of the new hybrids.

Background: For the past two decades, the assessment of the quality of diabetes care has mostly relied on clinical quality indicators. These have not included Patient-Reported Outcome Measures (PROMs) which provide information on outcomes deemed valuable by patients. We aimed to examine the potential utility of PROMs in type 2 diabetes care and to study the association of PROMs with patients' characteristics and clinical quality indicators.

The objective is to study the combined effect of an incident wave, a surface pressure excess and a finite number of submerged obstacles, in the phenomenon of power transfer to an infinite fluid layer of finite depth. The incident wave and the surface pressure excess have the same harmonic time dependence, a fact that allows to eliminate time altogether and consider only steady-state solutions. The surface pressure excess simulates the effect of winds blowing above the water surface in oceans.

Anxiety medications, muscle relaxants, and sleeping pills have the potential to cause complications, side effects, and withdrawal symptoms if not prescribed and managed appropriately. Tizanidine, a short-acting muscle relaxant, acts on central alpha-2-adrenergic receptors to reduce spasticity. However, abrupt withdrawal of tizanidine can lead to symptoms such as hypertension, reflex tachycardia, hypertonicity, and anxiety as a result of high adrenergic activity.

Vitamin D deficiency is a common health problem among adults in Saudi Arabia, particularly females. Vitamin D deficiency is associated with many diseases, including cardiovascular diseases, diabetes, autoimmune diseases, neurological disorders, and cognitive decline. This study aimed to assess the knowledge, awareness and practice of vitamin D deficiency among female students in Jazan University as well as to determine the sociodemographic related factors.

Liver fibrosis involves several signalling pathways working in concert regulating the deposition of extracellular matrix. In this study, we evaluated the effect of quercetin and simvastatin alone and their combination on the treatment of experimentally induced hepatic fibrosis in rats. To decipher the potential mechanisms involved, liver fibrosis was induced in rats by administration of 40 % carbon tetrachloride (CCl) (1 μl/g rat, i.

Methylene blue (MB) and its compounds are investigated for their potential benefits in the management of Alzheimer's disease (AD). AD is a widely seen neuropathological disorder characterized by the gradual decline of cognitive abilities, ultimately leading to the development of severe dementia. It is anticipated that there will be a significant increase in the prevalence of AD due to the aging population.

Out-of-hospital cardiac arrest (OHCA) remains a significant cause of death. The chance of survival significantly increases when immediate defibrillation with an on-site automated external defibrillator (AED) is available. Our aim is to systematically evaluate the impact of public access defibrillators (PAD) on the outcomes of outpatient cardiac arrest.

Atrial fibrillation (AF) is a prevalent cardiac dysrhythmia, particularly affecting older adults, with its prevalence rising due to the aging population. AF is linked to several adverse outcomes, including embolic stroke, heart failure, and cancer. The association between AF and cancer is intricate and not yet fully understood.

Background: The adverse effects of chemotherapy-induced diabetic peripheral neuropathy (CIDPN) are rather prevalent. There is no known pharmaceutical treatment that can stop CIDPN.

Objective: This study compared the effects of cold application and transcutaneous nerve stimulation (Transcutaneous electrical nerve stimulation (TENS)) on individuals who had undergone mastectomy following CIDPN.

Autoimmune enteropathy (AIE) is a differential diagnosis of incurable chronic diarrhea, malnutrition, and weight loss. This type of diarrhea is associated with protein enteropathy that usually affects the small intestine. The diagnosis of AIE is based on chronic diarrhea, malabsorption, specific histological result, antibodies against enterocytes, and excluding similar conditions.

We investigate nonlinear Rayleigh wave propagation in a layered thermoelastic medium composed of a slab rigidly bonded to the surface of a half-space under prescribed external thermal boundary conditions within the dual-phase-lag theory. The heat conduction coefficient for both the slab and the matrix have a linear dependence on temperature. Our aim is to assess the effect of temperature dependence of the heat conductivity, as well as the thermal relaxation times, on the process of wave propagation in the layered medium.

Background: Faulty dietary habits and overnutrition are prevalent among Egyptian patients with multiple sclerosis (MS) who do not receive nutrition care as part of treatment. Thus, this study was conducted to identify the effect of nutrition counseling on the nutritional status of patients with MS. This endeavor might provide evidence for the value of counseling in such a setting and advance the integration of nutrition counseling into the routine management of patients with MS.

Article Synopsis
  • - The study tracked 166 COVID-19 patients to analyze the prevalence and duration of symptoms over 18 months after their diagnosis, finding a mean of 2.3 symptoms initially, decreasing to 1.8 at 3 months and 0.6 at 18 months post-recovery.
  • - Some symptoms, like cough and loss of smell, significantly decreased after 3 months, while others like dyspnea (difficulty breathing) and weakness showed an increase during this time.
  • - By 18 months, all symptoms had generally reduced, but dyspnea, weakness, and brain fog remained notably present, indicating that some issues may persist long after recovery and should be addressed in post-COVID care.
