BACKGROUND:
Hepatitis C virus (HCV) infection has major health impact worldwide and is a significant cause of chronic liver disease. In Egypt, HCV is highly endemic (up to 15% of the population); 91% of the patients are infected with genotype 4. Searching for new predictors of response to therapy is mandatory to decrease the cost and the adverse effects of current therapy.
AIM:
The aim of this study was to clarify the usefulness of serum leptin, adiponectin, and insulin resistance (IR) as predictors of response to treatment in hepatitis C virus genotype 4 (HCVG4).
METHODS:
One hundred patients with chronic HCVG4 who were candidates for treatment with pegylated interferon α and ribavirin were included in the study. Age, sex, and BMI were determined, and quantitative HCV PCR, assessment of serum leptin, adiponectin, IR, and pretreatment liver profile, and liver biopsy were performed.
RESULTS:
The male to female ratio was 68/32; the mean age of the patients was 40.9 ± 7.8 years and BMI was 28.3 ± 10 kg/m. Sustained virological response (SVR) was achieved by 56% of the patients. On performing logistic regression, BMI [odds ratio (OR) 6.5; P=0.004], serum leptin (OR 27.8; P ≤ 0.001), aspartate aminotransferase (OR 1.06; P ≤ 0.001), IR (OR 1.15; P ≤ 0.001), histological activity index (OR 1.77; P=0.006), and fibrosis (OR 2.93; P=0.001) were found to be independent negative predictors of SVR, whereas serum adiponectin (OR 0.74; P ≤ 0.001) was found to be an independent positive predictor of SVR. Pretreatment adiponectin (cutoff 13.75; sensitivity 92.86%; specificity 86.86%) shows area under the curve of 0.879 (95% confidence interval 0.802-0.956; P<0.001) and insignificant area under the curve for leptin or IR.
CONCLUSION:
BMI, pretreatment high leptin levels, and IR are negative predictors for SVR and pretreatment low adiponectin levels are an independent positive predictor for SVR in HCVG4.

Intra-articular (IA) injection is grasping much interest due to the poor drug bioavailability at the targeted site of action which minimizes the effect of the orally administered moiety. Based on the integral role of non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment of Rheumatoid Arthritis (RA), much effort is exerted to develop novel localized drug delivery systems to increase their bioavailability and minimize their side effects. Artificial intelligence (AI) is acquiring an increasing role in the design of experiments being an effective tool for saving both time and resources. Hence, the aim of this work was to develop, characterize and optimize targeted forming nano particles (ISNs) for IA delivery of piroxicam using Design Expert as an AI-based application where a 3 full factorial experimental design was adopted. Morphological investigation, injectability, rheological studies, Fourier Transform Infrared Radiation (FTIR) as well as biological, histopathological, and biochemical examinations were performed to evaluate the optimized-ISNs. The optimized formulation, exhibiting a nano-sized particle size with a dense core, showed significant improvement in the histopathological findings compared to both the oral solution and the placebo. Additionally, the once-a-week IA administration of the optimized-ISNs proved a significant reduction in the protein expression of both STAT-3 and RANKL and the levels of anti-CCP and MCP-1 by almost 54 and 73%, respectively, coupled with a marked decline in the content of IL-17, MMP-3, NF-κB and TNF-α as compared to the positive control. In conclusion, the use of ISNs for intra-articular injection has demonstrated their effectiveness in piroxicam delivery for RA treatment.

Background: The appearance of scoliosis is one of the largest problems among stroke patients. Trunk and
pelvis abnormalities begin as a result of unequal weight distribution and muscle tightness. Presence of scoliosis
usually affect the position of scapula and pelvis which in turn causes impairments of motor, sensory and perceptual
functions of the upper and lower extremities. Objective: To assess trunk and pelvis malalignment in stroke patients in
relation to the duration of illness and degrees of spasticity. Methods: This study included sixty stroke patients, their
age ranged from 45 to 65 years. They were divided into equal groups according to the duration of illness. Each group
was subdivided into two subgroups according to the degree of spasticity. Clinical and neurological examination, brain
CT and MR imaging, assessment of muscle tone, trunk control and trunk range of motion were performed to each
patient. Results: There was no statistically significant difference concerning trunk flexion and extension among
patients in all groups. There was a statistical significant difference for trunk side bending among all patients. There
was a significant correlation between the degree of spasticity and both lateral trunk deviation and lateral pelvis tilting
as well as between duration of illness and abnormal trunk movements in all groups. Conclusion: Stroke patients
suffer usually from back and pelvis malalignment which are more manifested in long-standing patients with high
degrees of spasticity.

As a major ubiquitous secondary metabolite, flavonoids are widely distributed in . Among flavonoids, kaempferol is a typical natural flavonol in diets and medicinal plants with myriad bioactivities, such as anti-inflammatory activity, anti-cancer activity, antioxidant activity, and anti-diabetic activity. However, the natural sources, absorption and metabolism as well as the bioactivities of kaempferol have not been reviewed comprehensively and systematically. This review highlights the latest research progress and the effect of kaempferol in the prevention and treatment of various chronic diseases, as well as its protective health effects, and provides a theoretical basis for future research to be used in nutraceuticals. Further, comparison of the different extraction and analytical methods are presented to highlight the most optimum for PG recovery and its detection in plasma and body fluids. Such review aims at improving the value-added applications of this unique dietary bioactive flavonoids at commercial scale and to provide a reference for its needed further development.
