Background: Nutritional knowledge and practise is an important measure to improve dietary habits and food choices. The daily food should contain balanced nutrition as needed to support optimal growth, avoid deficiency diseases and prevent the diseases which might interfere with the children health. Materials & Methods: A descriptive cross-sectional non-interventional hospital-based study was carried out among 122 mothers and 122 children by using a non-probability convenience sampling technique in the period of 15 March to 15 April 2023, and using interviews with structural questionnaires, the data was analyzed using SPSS version 26. Results: We found that most of the children had moderate health, while most of the mothers had moderate nutritional knowledge and practise towards their children, also we found that the relationship between mothers’ knowledge and practise and child health was significant (P Conclusion: Mothers’ knowledge and practise among children was moderate and children had moderate health. Wrong beliefs and cultural taboos play major roles in decreasing knowledge and practise.

Hyaluronidase enzyme (HysA) is an extracellular enzyme that is considered to be an important virulence factor for Staphylococcus aureus. We screened the production of HysA enzyme in the spent media of Egyptian clinical isolates (32 isolates) via phenotypic plate assay. We found that 75% of the isolates (24 isolates) were able to produce HysA enzyme. We designed primers for qPCR analysis of hysA mRNA expression that was derived from the alignment of hysA gene sequences of 41 strains of S. aureus. The designed primers could be used for the amplification of hysA in 79.2% of the isolates (19 isolates) that were positive for HysA production as demonstrated by phenotypic plate assay. A significant positive correlation, as indicated by Pearson correlation analysis (r = 0.84 at P < 0.001), was found between phenotypic plate assay and qPCR of mRNA expression of hysA in the investigated isolates of S. aureus. In conclusion, we analyzed for the first time hysA mRNA expression via qPCR in S. aureus. Additionally, our work showed a good agreement between the phenotypic assay of HysA production via plate assay and hysA expression in S. aureus. The qPCR analysis of this study could be used as a more reliable quantitative method for hysA expression analysis particularly in infected animal models of S. aureus.

Cerebellopontine angle (CPA) lesions account for up to 10% of all intracranial tumors. Most CPA tumors are benign, but can cause nerve damage or compress the surrounding structures if left untreated. The typical presentation is with adult-onset sensorineural hearing loss or non-pulsatile tinnitus. In some patients, this goes unnoticed, and presentation is delayed until the lesion is much larger and presents with symptoms related to mass effect. We present the case study of 63 years old gentleman, who had suspected left CPA lesion on CT head done few years ago for dizziness and left-sided facial numbness. MRI could not be done at that time due to his MRI incompatible pacemaker leading to delay in his management eventually causing loss of patient to the follow up. He later developed progressive difficulty in walking which was initially attributed to as secondary to vasovagal syncope and postural hypotension. He eventually presented to us with intractable nausea and vomiting, worsening headache and ataxia. He had an urgent CT head which showed significant growth in the lesion with compression of the surrounding structures and obstructive hydrocephalus. He was given steroids which improved his nausea and vomiting, followed by undergoing surgery in regional center leading to significant improvement in his gait within few days of surgery. He unfortunately continued to have a degree of ataxia and facial numbness. This case illustrates a rare presentation of CPA tumor with symptoms of nausea and vomiting as a result of mass effect of the growing tumor. In addition, this review also shows the importance of regularly following up the patients with suspected CPA lesions on initial scans which will help with identifying the increase in size of lesion promptly and potentially preventing advanced complications of CPA tumors. We suggest regular monitoring of these patients to timely manage the lesion and avoid the potential life-threatening complications.

Introduction: Viral load suppression is a key determinant of successful anti-retroviral therapy. The study aimed to determine virologic response to Antiretroviral therapy in the large cohort of children and adults living with Human Immune deficiency Virus. Materials and Methods: Viral Load results from the HIV Ribonucleic Acid Polymerase Chain Reaction register of 10,887 children and adults on cART in 4 states in Northern Nigeria between 2017 and 2019 were retrieved and analyzed in the PCR Molecular Laboratory of the Federal Teaching Hospital, Gombe. Results: 10,887 children and adults were analyzed. Males were 28.4% (3094) and 71.6% (7793) females. 2.9% (311);3.5% (386);7.3% (797);65.2% (7098);14.5% (1583);5.2% (562) and 1.3% (150) were aged 0 - 9 years, 11 - 18 years;19 - 25 years, 26 - 45 years;46 - 55 years;56 - 65 years and 10 years. The most recent CD4count before viral load request was ≥1000/μL in 7.4% (810/10887);500 -999/μL in 39.0% (4240);350 - 499 μL in 22.7% (2466) and 1000 c/mL in 26.5% (821/3094) males and 24.1% (1876/7793) females. Viral load was significantly lower among females (p-value 0.007). 50.5% (157/311);52.1% (201/386);28.5% (227/797);23.5% (1670/7098);19.9% (315/1583);17.8% (100/562) and 18.0% (27/150) aged 0 - 9 years, 11 - 18 years;19 - 25 years, 26 - 45 years;46 - 55 years;56 - 65 years and 1000 c/mL respectively. Viral load was >1000 c/mL in 28.2% (229/811) for those on HAART for 6 months - 1 year and 23.6% (1243/5275) after receiving Highly Active Antiretroviral Therapy (HAART) for 1 - 5 years. 26.3% (1072/4075) and 21.1% (153/726) had viral load > 1000 c/mL after receiving HAART for 6 - 10 and >10 years respectively (p-value 0.001). Conclusion: HIV viral suppression was below the WHO recommended threshold.

Mitral and tricuspid valve surgery is increasingly being performed through a right mini-thoracotomy approach. Although valve repair is preferred over replacement whenever possible, valve replacement may be required in certain patients. In situations where the mitral or tricuspid anatomy are unfavorable and exposure is difficult, seating a prosthetic valve in the annulus through a right mini-thoracotomy approach may be difficult, compared to conventional sternotomy approach. This is complicated by limited tactile feedback in the minimally invasive approach. Herein, we describe several simple maneuvers that facilitate proper prosthetic valve seating and visualization of the posterior annulus during minimally invasive valve operations via right mini-thoracotomy.

Background: The correlation between oral health and dental restoration is fundamental. For the gingival and periodontal tissues to stay healthy, dental restoration should be in regularity with the surrounding tissues. This study aims to assess the oral health status and histopathological gingival response to three different restorative materials among Saudi patients. Methods: The study groups consist of 240 patients (50% males and 50% females), aged 18 - 45, with inclusion and exclusion criteria in the study. Participants are divided into three equal groups: those with composite resin restorations, those with amalgam restorations and those with glass ionomer restorations. Biopsies were taken from adjacent gingival tissues. Clinical parameters were determined by: plaque index (PLI), gingival index (GI) and clinical attachment loss (CAL). All data were collected and evaluated by through statistical analysis. Results: The clinical findings of the current study revealed that amalgam restorations produce a higher means of PLI, GI and CAL compared with composite resin restorations and glass ionomer restorations, but not insignificant levels, except CAL (p = 0.004*). As for histopathological findings, there were significant differences in gingival tissue response to amalgam restorations, composite resin restorations and glass ionomer cement fillings, where there were statistically significant differences in numbers of chronic inflammatory cells (p Conclusion: At the end of the present study, we concluded that the amalgam restorations are less biocompatible compared to composite resin restorations and glass ionomer restorations.

In the present paper, Copper Phthalocyanine (CuPc) thin films were deposited on glass and silicon substrate by thermal evaporation and pulsed laser deposition (PLD) methods. CuPc thin films prepared at different annealing temperatures (298, 323, 348, 373, 423 K) respectively. The structure and surface morphology of CuPc in powder and thin films forms prepared by two methods were studied using Energy dispersive X-ray (EDX), X-ray f§lt;span§gt;lorescence (XRF), X-ray§lt;/span§gt;diffraction (XRD), Atomic force microscope (AFM), and Scanning electron microscope (SEM). It showed that there was a change and enhancement in the crystallinity and surface morphology due to change in the annealing temperature (T§lt;sub§gt;a§lt;/sub§gt;). The purpose of our work is to find the optimal temperature for which the film produces best structural properties for CuPc thin film to produce organic field effect transistor. Analysis of X-ray diffraction patterns of CuPc in powder form showed that it had an α-poly-crystalline phase with monoclinic structure, with preferentially oriented (100) plane transform to §lt;i§gt;β§lt;/i§gt;-single crystalline morestable structure at different annealing temperatures.
