Abstract
Meningitis, an inflammatory disease affecting the meningeal layers of the brain and the spinal cord, poses a significant public health concern globally. Most meningitis cases are caused by viral infections, bacterial infections being the second most common cause, while fungal or parasitic infections are deemed rare. Despite the decrease in bacterial meningitis because of vaccination and treatment, a recent meningitis outbreak in the United States and Mexico highlighted ongoing challenges. The current meningitis outbreak is caused by a pathogenic fungus and is associated with surgical procedures performed under spinal anaesthesia as reported by the Centers for Disease Control and Prevention (CDC) on the 11 May of 2023. Around 20 cases with clinical suspicion of meningitis, including two fatalities, have been attributed to this rampant outbreak. Timely diagnosis, utilising diagnostic modalities such as lumbar puncture and pathogen detection methods, is crucial for appropriate management. Iatrogenic meningitis must be avoided by enhancing surveillance, infection control procedures, and adherence to aseptic practices. To lessen the effects of meningitis and enhance patient outcomes, the WHO's roadmap and preventive interventions, such as targeted immunisations, are essential.

Abstract
Powassan virus (POWV) is a tick-borne Flavivirus primarily transmitted through ticks in North America which is a significant public health threat in the northeastern United States. POWV infection spans from Ontario to the Mid-Atlantic, Northeast, and Midwest regions in the USA. Climate change, ecological factors, and human-related changes, including shifts in migration and agriculture, contribute to the dissemination of POWV. Symptoms include sore throat, fatigue, headache, and severe neuroinvasive conditions. Specialized attention is required for diagnosing and managing. MRI scans detect central nervous system abnormalities, while neuromonitoring identifies metabolic distress. Severe cases may necessitate ICU hospitalisation with continuous monitoring. Prevention measures, such as awareness, controlling mammals, and protecting pets, reduce POWV infection risk. The recent outbreak of POWV in Maine, USA, highlights the importance of worldwide collaboration for prevention. With the global prevalence of POWV increasing due to climate and socioeconomic changes, implementing preventative measures and promoting awareness are crucial in reducing infection risk.

Abstract
OBJECTIVE Patients with chronic disease whose treatments are limited may experience depression, anxiety, and stress-related symptoms, as well as an increase in the levels of these conditions. This study aims to determine the factors affecting the depression, stress, and anxiety levels of hepatocellular carcinoma (HCC) patients due to the fear of COVID-19 exposure. PATIENTS AND METHODS 118 patients with advanced HCC treated with non-transplant treatment options or on the waiting list due to the lack of a donor were enrolled. To evaluate the stress, depression, and anxiety levels during the COVID-19 process, Depression Anxiety Stress Scales (DASS-21) and the Coronavirus Anxiety Scale (CAS) were administered to 118 patients through a face-to-face interview. Sociodemographic and clinical characteristics were recorded, and the primary endpoint measure was the total score of DASS. In addition, the multilayer perceptron (MLP) model was constructed to predict the scores of the DASS-21 total. RESULTS There were significant differences between DASS depression (p=0.010; p=0.030) DASS anxiety (p=0.010; p=0.010) and DASS total (p=0.046; p=0.023) scores in terms of gender and protective effect of the vaccine. Also, a significant difference between gender for the CAS scale was determined (p=0.044). The median score of the DASS total in the COVID-19 group was higher than in the non-COVID-19 group; however, the increase was not significant. MLP model revealed that chronic disease, gender, age, place of residence, smoking, type of vaccine, and COVID-19 exposure were the most important predictors for the DASS total. CONCLUSIONS Chronic disease, gender, and age were prominent factors in predicting the DASS-21 total score in HCC patients. Therefore, the crucial factors were clinically considered for managing depression, stress, and anxiety in HCC patients.

Abstract
BACKGROUND Acute ischemic stroke is one of the leading causes of disability and mortality globally, with increasing incidence in Africa, as the continent is already burdened with infectious diseases. Rapid diagnosis and efficient treatment are crucial, as even a slight delay to reperfuse the brain significantly affects the recovery outcome. Neuroimaging is vital for optimal care and thrombolytic or endovascular therapy in specialised stroke care units. This review aims to discuss the burden of acute ischemic stroke in Africa and how healthcare systems have tried to reduce the incidence and improve outcomes for the disease. METHODOLOGY Data was collected from online databases and medical journal published on PubMed, Ovid MEDLINE, ScienceDirect and Embase bibliographical data. All articles related to acute ischemic stroke in Africa were considered. RESULTS The medical care for acute ischemic stroke in Africa is far from optimal with little adherence to recommended protocols. There is a lack of public awareness of the disease, imaging infrastructure, personnel, stroke care units and recovery facilities, due to poor funding. Poor knowledge of stroke signs and symptoms results in delay in treatment and poor prognosis. CONCLUSION We urge African leaders and private entities to invest in stroke care by building appropriate infrastructures, providing medical equipments, implementing guidelines, and sustainable follow-up systems. Telehealth is a suggested strategy to mitigate the scarcity of health personnel, and international and national efforts to increase treatment affordability should be doubled. Further extensive research on the impact of acute ischemic stroke on the African continent population is encouraged.

Abstract
Introduction Human Immunodeficiency virus (HIV) is a virus that causes several diseases by attacking the human immune system. It is transmitted by contact with certain bodily fluids of an infected person, most commonly during unprotected sex, through sharing needles, or from mother to baby during pregnancy, birth or breastfeeding. The central nervous system is not spared from this virus, as HIV has been shown to induce several neurological disorders. However most neurological pathologies (such as dementia, infections, meningitis, and neuropathy) rarely show until late stages, in this case, after the patients develop acquired immunodeficiency syndrome (AIDS). This article aims to review the neurological disorders in the HIV population and the attempts initiated to limit the disease. Methodology Data were collected from medical journals published on PubMed, Ovid MEDLINE, Science Direct and Embase bibliographical databases with a predefined search strategy. All articles considering neurological disorders associated with HIV were considered. Results To date, the pathogenesis of HIV‐associated neurological complications remains poorly elucidated; thus, imposing a hindrance and limitations on the treatment options. Nevertheless, some studies have reported alterations in dendritic spine as the causative agent for developing brain damage. Conclusion HIV remains one of the most serious global health challenges, with neurological manifestations imposing a major concern among patients with HIV. Despite the availability and efficacy of antiretroviral therapies, yet, the risk of developing neurological complications remains relatively high among patients with HIV. Thus, the 2030 HIV vision must focus on further preventive measures to protect HIV patients from developing such neurological complications.

Abstract
Background and Aim Platelet-rich fibrin (PRF) can be named as a natural fibrin-based biomaterial favorable to increasing vascularization and able to guide epithelial cell migration to its surface. The membrane has a significant positive effect on protecting open wounds and accelerating healing. Similar to PRF Ankaferd Blood Stopper (ABS) also has positive effects on wound healing. The aim of this study was to detect if we can improve known physical properties of PRF combining with ABS. This idea was based on the known mechanism of ABS in forming protein network without damaging any blood cells. Materials and Methods: A total of 25 adult rabbits used for collecting 5-7 ml of blood passively with the help of winged blood collection needle to the test tube. Collected samples were centrifuged at 3000 rpm for 10 min. Two similar samples obtained from each animal and one of the samples was placed in 20% ABS 80% saline solution for 5 min. Mechanical properties of the membrane samples were measured using Universal Testing Machine. Results: There is the statistically significant difference between PRF and ABS added PRF in elongation/mm (dL) and elongation/% at break values. Maximum force (fMax) and modulus values did not show any statistically significant differences. Conclusion ABS loaded PRF causes better physical properties. This combination seems to exhibit superior performance when used as a membrane barrier solely. Advanced studies can be done on biological properties of ABS loaded PRF, especially on tissue healing.

Abstract
AIM To examine the value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for the detection of bone metastasis in breast cancer patients and assess whether whole body bone scan (BS) with (99m)Tc-methylene diphosphonate provides any additional information. MATERIAL AND METHODS Study group comprised 150 patients, mean age 52 years (range 27-85) with breast cancer, suspected of having bone metastases. All patients had undergone both FDG-PET/CT and BS with or without single photon emission tomography/computed tomography (SPECT/CT) within a period of 6 weeks. The final diagnosis of bone metastasis was established by histopathological findings, additional imaging, or clinical follow-up longer than 10 months. Cancer antigen 15-3 (CA15-3) and carcinoembryogenic antigen (CEA) were measured in all patients. RESULTS Histologically 83%, 7% and 10% had infiltrating ductal, lobular and mixed carcinoma respectively. Confirmed bone metastases were present in 86 patients (57.3%) and absent in 64 (42.7%). Mean CA15-3 and CEA values in patients with bone metastases were 74.6ng/mL and 60.4U/mL respectively, compared to 21.3ng/mL and 3.2U/mL without metastases (p<0.001). The sensitivity of FDG-PET/CT for the detection of bone metastases was 97.6% compared to 89.5% with SPECT/CT. In 57 patients, FDG-PET/CT correctly identified additional pulmonary, hepatic, nodal and other soft tissue metastases, not detected by BS. CONCLUSION Our findings suggest that FDG-PET/CT is superior to BS with or without SPECT/CT.

Abstract
OBJECT To record emmetropization, visual acuity, and strabismus outcomes among hyperopic infants followed with partial hyperopic corrections given in accordance with dynamic retinoscopy (DR). METHODS Infants (3.5-12 months of age) with ≥5 D hyperopia were followed without glasses or partial hyperopic corrections prescribed according to their near dynamic accommodative abilities determined by DR responses at the initial visit and follow-ups. Refraction and binocular accommodative ability assessments were made at 3-month intervals up to the age of 1 and at 6-month intervals afterwards for a mean 35.4±2.1 months; main outcome measures being the development of esotropia, emmetropization rate, and visual acuity level after emmetropization period. RESULTS Among 211, 146 were normal accommodators initially (Group 1). These infants were followed without treatment and none presented with strabismus. Sixty-five infants were hypo-accommodators (Group 2) and received minimum DR-based corrections. Of the 65 infants 31 (48%) developed strabismus (Group 2B). The remaining 34 constituted Group 2A. Each of the three groups showed an overall reduction of hyperopia by 0.37±0.25 days per year, 0.50±0.28 days per year, and 0.60±0.20 days per year, respectively. Visual acuity assessments among Groups 1 and 2A revealed normal values (0.2-0.0 LogMAR); among Group 2B 19% were within normal range. CONCLUSIONS Binocular accommodative behavior at the initial visit seems to be one of the indicators for pointing out infants at risk of developing strabismus and amblyopia. Prescription of DR-based corrections to hyperopic orthotropic infants does not impede emmetropization and result in normal visual acuities after emmetropization period.

Abstract
BACKGROUND Total vascular exclusion (TVE) causes warm liver ischemia. The aim of this study was to investigate the patterns of injury caused by inflow-outflow obstruction in the rat liver. MATERIALS AND METHODS Twenty-four Wistar-Albino rats were divided into three groups: liver inflow occlusion (Group A), inflow-outflow occlusion (Group B) and intermittent inflow-outflow occlusion applied for 15 minutes. Microcirculation was measured with laser Doppler flowmetry during the procedure. Samples for biochemical and histopathological analyses were collected at the end of the ischemia period. RESULTS Significant alterations in microcirculation were determined by application of vascular control maneuvers. Microcirculation in the central and dome segments were affected adversely compared with the dome segments in all experimental groups. TVE induced severe disturbances in hepatic microcirculation with more prominent hepatocellular damage. Damage to central segments of the rat liver was more prominent with inflow occlusion; whereas inflow-outflow occlusion produced more prominent damage to dome segments. Intermittent application of TVE clamping was associated with more hepatocellular damage compared with continuous TVE. CONCLUSION Our mapping methodology within the liver parenchyma suggested that hepatovenous back-perfusion is a principle source of continuity of microcirculation in the rat liver during inflow occlusion. Inflow-outflow occlusion caused more tissue damage compared with inflow occlusion. Ischemic preconditioning during TVE did not increase the tolerance of the liver against ischemia.

Abstract
Zoledronic acid (ZA), a nitrogen-bearing bisphosphonate, is used to treat the hypercalcemia associated with cancer. In addition to its antiumor effects, it acts as an osteoclast inhibitor. To investigate the effects of ZA on oxidative stress and antioxidants, we studied reduced glutathione (GSH) and antioxidant gamma glutamate cysteine, including nitrite and nitrate, which are endproducts of nitric oxide (NO) as well as malondialdehyde (MDA) in rabbit liver tissue. In the study ZA (100 μg/kg) was administered to 7 rabbits that were fed ad libitum for comparison with untreated controls. MDA was studied using Thiobarbituric acid-reactive substance reduction, NO using cadmium reduction, GSH using an enzymatic method yielding dithinitrobenzene yellow substance. We observed significantly higher MDA and NO levels in the ZA group (P < .0001), whereas GSH levels were significantly lower (P < .0001). Tissues were examined histopathologically. According to our results we find ZA induced rabbit liver oxidative stress and decreases with antioxidant levels in liver tissue. Further studies are needed to explore the safe use of this agent.

Abstract
BACKGROUND Even though the genotype at the promoter region of the CD14 molecule is known to affect the atopic phenotypes, the cellular and molecular basis of this association is largely unknown. OBJECTIVE To investigate the effect of lipopolysaccharide (LPS) on IgE production and cytokine profile by peripheral blood mononuclear cells (PBMC) obtained from asthmatic children with the TT and the CC genotypes at position -159 of the CD14 gene. METHODS Peripheral blood mononuclear cells from asthmatic children with alternative genotypes at CD14 C159T locus were stimulated with 2 and 200 ng/ml LPS in vitro. The IgE, IgG and, IgM response was determined by ELISA and Ig έ-germline, IgG, and IgM transcription by real-time PCR. A cluster of cytokines was measured by cytometric bead array. RESULTS Asthmatic children with the TT genotype but not those with the CC genotype responded with increased IgE synthesis and germline transcription to LPS stimulation. There were no genotype-related differences in IgG and IgM. TT but not the CC genotype was associated with significantly increased interleukin (IL)-4/IL-12 and IL-4/interferon-gamma (IFN-γ) ratios in the culture supernatant. There were no genotype-related differences in IL-1β, IL-7, IL-10, IL-13, IL-17A, granulocyte colony stimulating factor, granulocyte macrophage colony stimulating factor, monocyte chemotactic protein, and tumor necrosis factor alpha. CONCLUSION Peripheral blood mononuclear cells from asthmatic children with the TT genotype at position -159 of the CD14 gene make more IgE than those with the CC genotype following LPS stimulation because of increased germline transcription and have an augmented Th2 cytokine profile.

Abstract
Our objective was to determine the factors that affect (i) the rectal-axillary temperature measurement difference (RATD) for digital and mercury-in-glass thermometers and (ii) the difference between mercury-in-glass and digital thermometer readings taken by the rectal and axillary routes. Children (between the ages of 2 and 48 months) who were admitted to Hacettepe University Children Hospital and Corum Children's Hospital in 2 months period were included in this study. Two measurements were taken from each patient within 2 days at two different occasions including day/night and sleep/awake by the same physician. A total of 135 patients were enrolled. RATD was 0.61 + 0.54 degrees C in the mercury-in-glass thermometer, and 0.81 +/- 0.57 degrees C in the digital thermometer. The mean differences between digital and mercury-in-glass thermometers were 0.16 degrees C for rectal routes and -0.02 degrees C for axillary routes. Children at older age with hypoalbuminemia and children exposed to higher ambient temperatures had lower values of RATD than others. Temperature recordings from different sites might change with ambient temperature and individual characteristics of children.

Abstract
BACKGROUND AND PURPOSE Myelin instability and citrullinated myelin basic protein have been demonstrated in the brains of patients with chronic and fulminating forms of multiple sclerosis (MS). Our aim was to trace citrulline in the brains of patients with early-onset MS by using proton MR spectroscopy ((1)H-MR spectroscopy). MATERIALS AND METHODS A short-echo single-voxel (1)H-MR spectroscopy by using the point-resolved proton spectroscopy sequence was performed in 27 patients with MS and 23 healthy subjects. Voxels of interest were chronic demyelinating lesions (CDLs, n = 25) and normal-appearing white matter (NAWM, n = 25) on T2-weighted imaging, and when available in patients with MS, enhancing demyelinating lesions (EDLs, n = 8). Frontal white matter (WM) was studied in control subjects. N-acetylaspartate, choline, and myo-inositol (mIns)-creatine (Cr) ratios and the presence of a citrulline peak were noted. RESULTS Citrulline peaks were more frequently observed in patients with MS than in control subjects (P = .035), located in the NAWM in 8/25 (32%), in CDLs in 7/25 (28%), and in EDLs of 1/8 (12.5%) patients with MS. The presence of citrulline and measured metabolite/Cr ratios was not related to age at imaging, age at disease onset, duration of disease, or number of relapses. There was no significant metabolic difference between the NAWM of patients with MS and the WM of the control subjects. mIns/Cr was significantly greater in CDLs compared with the NAWM of patients with MS and the WM of healthy subjects. CONCLUSIONS Citrulline was more frequently identified in the brains of patients with early-onset MS than in healthy subjects by (1)H-MR spectroscopy, suggesting an association of increased citrullination of myelin proteins with demyelinating diseases.

Abstract
Better clarification of the long-term relationship among the various implant-related measures could improve the evaluation process for dental implants. Thus, the aim of the present study was to determine the potential correlations among the volumetric features and nitric oxide content of peri-implant sulcus fluid (PISF) and measures of implant stability, and the marginal bone loss. Completely edentulous patients (n=15) treated with dental implants and ball attachment mandibular over dentures were included. Resonance frequency analysis (RFA), marginal bone level measurements, PISF volume and spectrophotometrically determined nitrite levels were recorded for all dental implant sites. Measures for early (n=16) and delayed (n=14) loaded dental implants were comparatively analysed for a period of 18 months. Some random correlations between PISF volume and marginal bone level, PISF nitrite level and marginal bone level and PISF volume and PISF nitrite content, and RFA and PISF volume were observed. However, the only constant correlation was noticed between implant stability (RFA scores) and marginal bone level. This correlation was negative and significant for all dental implants and for delayed loaded implants (P<0.05). The pattern of loading seemed to affect the extent, but not the pattern of this relationship. While some of the implant-related measures may be strongly associated (e.g. dental implant stability and marginal bone level), not all measures from a single implant site are likely to be related. Such associations may be under the influence of a variety of factors including the loading protocol of dental implants.

Abstract
BACKGROUND Predictive factors of childhood asthma for favorable prognosis may differ between populations where a variety of genetic and environmental factors are present. OBJECTIVES To document the factors predicting disease persistence in early adulthood in Turkey. METHODS An outpatient cohort (n = 115) with a mean follow-up duration of 11.4 +/- 0.2 years was evaluated. Complete remission was defined as no asthma symptoms, no use of controller medication, no airflow limitation and no airway hyper-responsiveness, and clinical remission as no symptoms and no use of controller medication, within the past year. RESULTS The mean ages during referral and at the final visit were 5.8 +/- 0.2 and 17.1 +/- 0.2 years, respectively. Thirty-one (27%) were in complete remission, and a further 30 (26%) in clinical remission. In multivariate logistic models, diminished airflow [forced expiratory volume in 1 s (FEV1) < 80% vs > or = 80%] at the initial lung function test predicted current diminished airflow (8.422; 2.202-32.206) (odds ratio; 95% confidence interval), and presence of obstructive pattern (FEV1/forced vital capacity (FVC) < 80% vs > or = 80%) predicted current obstructive pattern (29.333; 3.022-284.724). Furthermore, female gender appeared to predict persistence of asthma symptoms (3.330; 1.250-8.333) and absence of clinical remission (2.398; 1.038-5.254); eosinophilia predicted persistence of symptoms (4.271; 1.080-16.889) and presence of airway hyper-responsiveness (3.723; 1.129-12.278). CONCLUSIONS Diminished airflow, female gender and eosinophilia appear to predict an adverse outcome of childhood asthma, supporting the concept that variability may exist between populations.

Abstract
INTRODUCTION The enamel in pits and fissures undergoing preventive or ultraconservative resin restorations may be affected by secondary caries. An antibacterial adhesive bond may be a useful choice to prevent and reduce demineralization. OBJECTIVES The purpose of this study was to determine the shear bond strength of an experimental antibacterial bond, a self-etch bond, and an ormocer-based adhesive bond using an ormocer-based fissure sealant and a composite resin on intact enamel. METHODS Twenty-four extracted human molars were sectioned bucco-lingually to obtain two flat and sound enamel surfaces. Forty-eight specimens were randomly assigned into four groups. The groups were prepared to receive the following treatments: (1) Admira Bond + Admira Seal (n = 10); (2) ABF Bond + Admira Seal (n = 11); (3) Clearfil SE Bond + Clearfil AP-X (n = 12); and (4) ABF Bond + Clearfil AP-X (n = 11). A cylindrical mould was placed over the bonded surface, and both materials were applied according to the instructions. The teeth were thermocycled 500 cycles between 5 and 55 degrees with a dwell time of 30 s. For shear bond strength testing, the load was applied vertically to the base of the mould. The cross-head speed was 5 mm min(-1). RESULTS The maximum load that a specimen can withstand until failure was determined and shear bond strength was calculated by dividing the load at failure by the surface area of the mould. The results (median, minimum and maximum, respectively) for the four groups were: (1) 7.9, 4.2 and 13.6 MPa; (2) 8.6, 2.6 and 15.9 MPa; (3) 5.9, 5.3 and 8.2 MPa; and (4) 8.8, 3.0 and 19.2 MPa. Kruskal-Wallis and Mann-Whitney U-tests were performed for the statistical analysis. Groups 3 and 4 were statistically significantly different (P = 0.005; P < 0.05). There was no statistically significant difference between the sealant and composite groups for ABF (P = 0.375). Fracture sites were viewed by microscope under x 16 magnification to determine if the mode of failure was adhesive or cohesive. The results (number of adhesive failed specimens and number of cohesive failed specimens, respectively) for the four groups were: (1) 7 and 3; (2) 3 and 8; (3) 2 and 9; and (4) 8 and 3. CONCLUSION The ABF bond has sufficiently physical qualities to be used under fissure sealant and composite resin on uncut enamel, its antibacterial efficiency notwithstanding.

Abstract
PURPOSE To measure the retinal nerve fiber layer thickness in patients with pigment dispersion syndrome (PDS) using scanning laser polarimetry and to compare these measurements with those of normal subjects and patients with pigmentary glaucoma (PG). METHODS Age-, sex-, and refractive error-matched subjects--18 patients with PDS, 18 patients with PG, and 20 healthy subjects--were evaluated by scanning laser polarimetry (Nerve Fiber Analyzer [NFA] GDx). The NFA did not have a compensator for corneal polarization. One randomly selected eye from each patient was included in the statistical analysis. The NFA measurements of patients with PDS and PG and healthy subjects were compared statistically using analysis of variance, Tukey multiple comparisons, chi-square, and independent t-tests. RESULTS The mean values for average thickness, superior and inferior maximum, superior and inferior average, ellipse average thickness, and superior integral were found to be lower in the patients with PDS (p < 0.02) and PG (p < 0.005) compared to the normal subjects. The mean values for maximum modulation, superior ratio, inferior ratio, and superior/nasal ratio in PDS were in between those of the PG and control groups (p > 0.05). The ellipse modulation was significantly lower in the PG group when compared to the other two groups (p < 0.03). CONCLUSIONS Retinal nerve fiber loss is present to some extent in patients with PDS and this loss is not age or sex dependent. Parameters of modulation might be more representative of significant damage of the nerve fiber layer.
