Abstract
Human herpesvirus type 6 (HHV-6) is a DNA virus considered a member of the Herpesviridae family. HHV-6 is acquired early in life, when it may cause roseola infantum and nonspecific febrile illnesses which is usually a self-limiting disease before the age of two. Primary HHV-6 encephalitis and acute necrotizing encephalopathy (ANE) are rare diseases to occur in immunocompetent children. We describe an unusual case of HHV-6 encephalitis with mixed features of acute necrotizing encephalopathy and acute disseminated encephalomyelitis and contextualize it with a review of the literature on HHV-6 encephalitis in immunocompetent children. Although the incidence of primary HHV-6 encephalitis is rare in immunocompetent children, HHV-6 encephalitis associated with acute necrotizing encephalopathy is a devastating disease, highly fatal and neurologically damaging disease. Therefore, early testing and diagnosis are crucial as well as effective management of encephalitis with antiviral therapy is highly recommended.

Abstract
Diffuse gliomas are incurable, prevalent, and aggressive central nervous system tumors. Therefore, the development of selective oncolytic viral strains for malignant neoplasms is highly relevant. This study aimed to create an oncolytic virus based on a vaccine strain of poliovirus type 3 with natural antitumor activity. To achieve this goal, we replaced the internal ribosome entry site (IRES) of poliovirus with the corresponding fragment of human rhinovirus 30. The resulting recombinant oncolytic strain RVP3 retained the serotype of poliovirus type 3, as confirmed by virus neutralization micro-test with specific antiserum. In addition, the oncolytic efficacy of RVP3 was assessed in vitro on a broad panel of cell cultures. According to the results, RVP3 has changed its tropism, losing the ability to replicate in conditionally normal cell lines of embryonic astrocytes and embryonic fibroblasts while retaining the ability to replicate in tumor cells.

Abstract
Background Inhibitors of the anaplastic lymphoma kinase (ALK) gene mutation are highly effective treatments for ALK-positive lung cancer. We conducted this pharmacovigilance analysis using the Food and Drug Administration Adverse Event Reporting System (FAERS). Patients and methods FAERS files from 2012 to 2020 were used. Reports for crizotinib, ceritinib, alectinib, brigatinib, and lorlatinib were filtered. We used the Medical Dictionary for Regulatory Activities (MedDRA version 22.1). Further, we searched for adverse events on the preferred term (PT) level based on case reports in the literature. After filtering duplicate reports, disproportionality analysis was used to detect safety signals by calculating proportional reporting ratios (PRRs), reporting odds ratios (RORs), empirical Bayesian geometric mean, and information component. Reports were considered statistically significant if the 95% confidence interval did not contain the null value. Results Within the system organ classes, significant safety signals were found, including those for crizotinib [eye disorders (PRR 2.09, ROR 2.12)], ceritinib [gastrointestinal disorders (PRR 2.19, ROR 2.41), hepatobiliary disorders (PRR 4.4, ROR 4.52), respiratory disorders (PRR 1.96, ROR 2.08)], alectinib [hepatobiliary disorders (PRR 2.60, ROR 2.63)], brigatinib [respiratory disorders (PRR 2.15, ROR 2.31)], and lorlatinib [metabolism disorders (PRR 3.34, ROR 3.53)]. For adverse events on the PT level, we found several significant signals, including pneumothorax with crizotinib (PRR 3.29, ROR 3.29), ceritinib (PRR 3.13, ROR 3.13), and alectinib (PRR 4.88, ROR 4.89); myasthenia gravis with lorlatinib (PRR 6.05, ROR 6.05); photosensitivity reactions with crizotinib (PRR 2.20, ROR 2.20), ceritinib (PRR 4.30, ROR 4.31), alectinib (PRR 20.43, ROR 20.51), and brigatinib (PRR 20.97, ROR 21.05); pulmonary arterial hypertension with brigatinib (PRR 2.92, ROR 2.92) and lorlatinib (PRR 9.2, ROR 9.24); and rectal perforation with crizotinib (PRR 7.83, ROR 7.83). All the detected safety signals were confirmed using Bayesian methods. Conclusion ALK inhibitors differed in their safety profile reports. We found several significant safety signals that matched previously published case reports, including pulmonary arterial hypertension, rectal perforation, myasthenia gravis, and photosensitivity. These signals require further regulatory investigation to determine their significance and potentially update the product labels to inform patients and clinicians.

Abstract
Background: Clove and lemon basil are widely used in Indonesian culinary and known for their antimicrobial properties. This study was designed to identify the chemical constituents of single clove and lemon basil Essential Oils (EOs) as well as determine the potential of the combinations of both EO for preserving chicken meats.
Methods: The compositions of clove and lemon basil EOs were evaluated with Gas Chromatography-Mass Spectrometer. Three different concentration ratios of the combination of clove and lemon basil EOs (2:0.2, 1:1, and 0.1:2% v/v) were prepared along with single clove and lemon basil EOs in a concentration of 1% v/v. Their potential preservation effect was evaluated by observing the reduction of the microbial growth on the meats by evaluating Optical Density (OD) of cultured bacterial suspensions during 15 days of refrigerated storage. Statistical analyses were conducted by SPSS Statistics v. 20.
Results: The major constituents of clove EO were eugenol, β-caryophyllene, and αhumulene, while those of lemon basil were estragol, linalool, E-citral, and Z-citral. Both treatment groups and storage time affected significantly on ODs of the samples. Combination of these two EOs, particularly at the optimum ratio of 1:1%, showed the best microbial inhibitory activity, and delayed the sensorial changes of the meats for 12 days.
Conclusion: The combinations of cloves and lemon basil EOs showed a better microbial growth inhibitory activity and preservation potential than those of the single use. This meat preservation effects might be related to the presence of high fractions of oxygenated compounds, mainly eugenol, Z-citral, and E-citral in both clove and lemon basil EOs.

Abstract
Recombinant herpesviruses can be used as oncolytic therapeutic agents and high packaging capacity vectors for delivering expression cassettes into the cell. Herpesvirus saimiri is a gamma-herpesvirus that normally infects squirrel monkeys but also has a unique ability to infect and immortalize human lymphocytes while allowing them to retain their mature phenotype and functional activity. Recombination of the Herpesvirus saimiri genome in permissive cells is impeded by its resistance to chemical transfection and electroporation. The aim of this study was to develop an effective method for incorporating expression cassettes into the genome of Herpesvirus saimiri without having to transfect a permissive cell culture. Transfected HEK-293T cells expressing glycoproteins of the measles virus vaccine strain were co-cultured with permissive OMK cells infected with Herpesvirus saimiri. Cell fusion and formation of syncytia stimulated recombination between the viral genome and the expression cassette; this allowed us to obtain a recombinant Herpesvirus saimiri variant without chemical transfection in permissive cells. The genetically modified virus expressed a selectable marker and retained its ability to persist in the cell in the latent state; it also caused immortalization of primary lymphoid cells. The proposed approach allows engineering recombinant Herpesvirus saimiri strains carrying a variety of expression cassettes in its genome.

Abstract
Abstract
Background
Left ventricular (LV) remodeling, through excessive inflammation, leads to heart failure. Exercise (Ex) training is associated with a risk reduction in heart failure through direct and indirect mechanisms by which Ex contributes an anti-inflammatory effect. During Ex, contracting muscle fibers release myokines, including interleukins (ILs), tumor necrosis factor α (TNF-α), follistatin-like protein 1 (FSTL-1), and fibroblast growth factor 21 (FGF-21), into the bloodstream. These myokines may have beneficial effects on other damaged organs, such as an infarcted myocardium, through anti-inflammatory effects. However, the exact mechanisms of the anti-inflammatory effects of voluntary Ex in myocardial infarction (MI) are poorly understood. Therefore, we investigated the effect of voluntary Ex on cardiac remodeling and inflammation, the relationship between cardiac remodeling and skeletal muscle (SKM) response, and circulating myokine levels in a mouse model of MI.
Methods
Twelve-week-old male C57BL/6J mice were used and divided into the following 4 groups: sham operation (Sham), MI, Sham+Ex, and MI+Ex. MI was induced by ligation of the left anterior descending coronary artery. Ex groups began voluntary wheel running for 4 weeks after the operation. An echocardiography was performed at baseline and 4 weeks after the operation. The mRNA levels in the LV infarcted area and SKM were measured with RT-PCR and western blot analysis. Plasma levels of myokines were also measured with immunoassays.
Results
Four weeks after MI induction, echocardiographic evaluation showed that the MI mice had a larger LV end-diastolic diameter (LVEDD) and end-systolic diameter (LVESD) than the Sham mice. The MI mice also showed higher mRNA levels of TNF-α, IL-1β, IL-6, and IL-10 in the LV tissue when compared to the Sham mice. These changes were significantly ameliorated in the MI+Ex mice. Interestingly, in the MI+Ex mice, mRNA levels of IL-6, IL-1β, FSTL-1, and FGF-21 in the SKM were significantly higher than in the MI mice, while there were no significant differences in TNF-α and IL-10 levels in all groups. Similarly, protein expression levels of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, sirtuin-1, and mitochondrial transcriptional factor A of mitochondrial function markers in SKM were also significantly higher in the MI+Ex mice than in the MI mice. Furthermore, there were significant correlations between plasma levels of IL-1β, but not other myokines, and LVEDD, and LVESD. In addition, there was also a significant correlation between the SKM IL-1β level and LVESD in the Sham+Ex mice (all, P<0.05).
Conclusions
Amelioration of cardiac remodeling and inflammation by voluntary Ex is associated with increased myokines, especially IL-1β, in a MI mouse model. These results suggest that increased myokine levels, through voluntary exercise, may play an important role in the prevention of cardiac remodeling after MI.

Abstract
AIM Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined. METHOD Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated. RESULTS The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms. CONCLUSION Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

Abstract
We present the measurement of the transverse single-spin asymmetry of weak boson production in transversely polarized proton-proton collisions at sqrt[s]=500 GeV by the STAR experiment at RHIC. The measured observable is sensitive to the Sivers function, one of the transverse-momentum-dependent parton distribution functions, which is predicted to have the opposite sign in proton-proton collisions from that observed in deep inelastic lepton-proton scattering. These data provide the first experimental investigation of the nonuniversality of the Sivers function, fundamental to our understanding of QCD.

Abstract
We present high precision measurements of elliptic flow near midrapidity (|y|<1.0) for multistrange hadrons and ϕ meson as a function of centrality and transverse momentum in Au+Au collisions at center of mass energy √[sNN]=200 GeV. We observe that the transverse momentum dependence of ϕ and Ω v2 is similar to that of π and p, respectively, which may indicate that the heavier strange quark flows as strongly as the lighter up and down quarks. This observation constitutes a clear piece of evidence for the development of partonic collectivity in heavy-ion collisions at the top RHIC energy. Number of constituent quark scaling is found to hold within statistical uncertainty for both 0%-30% and 30%-80% collision centrality. There is an indication of the breakdown of previously observed mass ordering between ϕ and proton v2 at low transverse momentum in the 0%-30% centrality range, possibly indicating late hadronic interactions affecting the proton v2.

Abstract
We report the observation of transverse polarization-dependent azimuthal correlations in charged pion pair production with the STAR experiment in p^{↑}+p collisions at RHIC. These correlations directly probe quark transversity distributions. We measure signals in excess of 5 standard deviations at high transverse momenta, at high pseudorapidities η>0.5, and for pair masses around the mass of the ρ meson. This is the first direct transversity measurement in p+p collisions.

Abstract
Collisions between prolate uranium nuclei are used to study how particle production and azimuthal anisotropies depend on initial geometry in heavy-ion collisions. We report the two- and four-particle cumulants, v_{2}{2} and v_{2}{4}, for charged hadrons from U+U collisions at sqrt[s_{NN}]=193 GeV and Au+Au collisions at sqrt[s_{NN}]=200 GeV. Nearly fully overlapping collisions are selected based on the energy deposited by spectators in zero degree calorimeters (ZDCs). Within this sample, the observed dependence of v_{2}{2} on multiplicity demonstrates that ZDC information combined with multiplicity can preferentially select different overlap configurations in U+U collisions. We also show that v_{2} vs multiplicity can be better described by models, such as gluon saturation or quark participant models, that eliminate the dependence of the multiplicity on the number of binary nucleon-nucleon collisions.

Abstract
BACKGROUND AND PURPOSE Stroke is a major health problem in Qatar, yet no stroke studies have been reported from this region. This hospital-based study was conducted to determine the types and the 30-day fatality rate of stroke. The data were collected from the only hospital in Qatar and, therefore, are considered to be community-based estimations. METHODS Clinical information was collected from discharge records of all patients with International Classification of Diseases, 9th Revision, (ICD 9) codes 430 to 438 from January 1 to December 31, 1997. Identification of cases included review of death certificates and brain computed tomography (CT) records for the same period. RESULTS First-ever stroke was found in 217 patients (157 men and 60 women). The overall incidence rate was 41 per 100,000 inhabitants per year (95% CI, 30.2-52.4/100,000/year) and 238/100,000/year for the population over 45 years old. The age standardized incidence was 57.5 per 100,000 inhabitants per year (95% CI, 43.1-73.8). The crude incidence for native Qataris was 75 per 100,000 inhabitants per year. The mean age of patients experiencing their first stroke was 57 years. Thirty-nine (18%) patients were younger than 45 years. Clinical subtypes of stroke were ischemic (80%), intracerebral hemorrhage (19%), and subarachnoid hemorrhage (1%). Risk factors included hypertension (63%), diabetes mellitus (42%), ischemic heart disease (17%), and atrial fibrillation (4.5%). The overall patient fatality rate at 30 days was 16%. CONCLUSION Stroke incidence in Qatar is lower than in other countries; a low incidence of subarachnoid hemorrhage was noted. The low mean age of stroke patients reflects the demographic characteristics of the population in Qatar. The high percentage of stroke patients suffering from hypertension and diabetes reflects the high prevalence of these risk factors in the population.

Abstract
INTRODUCTION Over one billion Muslims fast worldwide during the month of Ramadan. Fasting during Ramadan is a radical change in lifestyle for the period of a lunar month. The objective of this study was to investigate whether Ramadan fasting has any effect on the incidence of stroke and its outcome in a geographically-defined population. METHODS We retrospectively reviewed a 13-year stroke database and studied the data on Muslim patients who were hospitalised with stroke over a 13-year period from January 1991 to December 2003. Patients were divided according to the time of presentation in relation to the month of Ramadan, one month before, during, and one month after Ramadan. The number of hospitalisations for stroke in various time periods was analysed. The age of presentation, gender, cardiovascular risk factor profiles (smoking status, hypertension, hypercholesterolaemia, diabetes mellitus, and pre-existing cardiovascular disease) were analysed. We also studied the trends of in-hospital mortality, morbidity and acute medical care provided. RESULTS Overall, 335 Muslim patients were hospitalised for stroke. Their mean age and standard deviation were 56.99 and 13.9 years, respectively. The number of hospitalisations for stroke was not significantly different in the month of Ramadan (29 cases), when compared to the month before Ramadan (30 cases) and the month after Ramadan (29 cases). Risk factors included for stroke were not significantly different in Ramadan when compared to the month before and after Ramadan. These associated diseases were hypertension, diabetes mellitus, hypercholesterolaemia, acute myocardial infarction, and congestive heart failure. CONCLUSION This study demonstrated that no significant difference was found in the number of hospitalisations for stroke while fasting during the month of Ramadan when compared to the non-fasting months.

Abstract
The medical records of 219 epileptic patients seen over a period of eight years were reviewed to determine the incidence and causes of intractable epilepsy amongst adults in Qatar: The incidence rate of hospital admission with uncontrolled epilepsy was calculated as 25per 100,000persons. Thirty-nine patients (18%) fulfilled the criteria for IE and the incidence of IE could be approximated at 4.5 per 100,000 persons. In the native Qatari population the approximated incidence of IE would be 1 in 100,000 persons per year, while in the expatriate population the rate would be 3.5 per 100,000 persons per year. The most common type of IE was idiopathic generalized epilepsy (75%) followed by symptomatic epilepsy (19%) and temporal lobe epilepsy (6%). To calculate the crude incidence of epilepsy in Qatar, the records were reviewed of 1217patients (aged 13-85 years) visiting the outpatient department or admitted to hospital because of a newly diagnosed epilepsy during the calendar year, 1st January-31st December 2001. These figures were extrapolated to an approximation of an incidence of 174 in 100,000 persons per year.

Abstract
A 1-year prospective community-based study of malaria during pregnancy was conducted in an area of seasonal and unstable malaria transmission in eastern Sudan. At a village antenatal clinic, 89 non-pregnant controls and 86 pregnant women were enrolled and followed every 2 weeks until 6 weeks after delivery. The incidence of Plasmodium falciparum infection was significantly higher among pregnant than control women [17.4% versus 5.6%] with no difference between primigravidae and multigravidae [22.2% versus 15.2%]. There was no significant difference in the mean haemoglobin concentration between infected and uninfected mothers [9.1 +/- 1.3 versus 9.5 +/- 0.6 g/dL] but the mean birth weight of their babies was significantly lower [2.72 +/- 0.26 versus 2.95 +/- 0.05 kg] despite prompt case management of infected women

Abstract
A retrospective case-control study was conducted to determine whether liver cirrhosis might be a risk factor for radiocontrast induced nephropathy as has been suggested. Data from 72 patients with cirrhosis and 72 patients without cirrhosis who all received 100-150 ml of low osmolality radiocontrast medium for abdominal or chest computerized tomography scan were reviewed. Blood urea nitrogen and creatinine were recorded before and 48-72 h after the administration of an intravenous radiocontrast agent. Acute renal failure developed in two patients with cirrhosis (2.8%) and one patient in the control group (1.4%). This difference was not significant. There was no significant change in blood urea nitrogen and creatinine in either group after radiocontrast injection. Both of the cirrhotic patients who developed radiocontrast induced nephropathy had received high-dose diuretics and were hypovolemic. We conclude that hepatic cirrhosis per se may not be a risk factor for radiocontrast-induced nephropathy.

Abstract
Intravenous labetolol, a nonselective alpha- and beta-blocking drug, is commonly used to treat severe hypertension. Nonselective beta-blockers can cause hyperkalemia, especially in patients with renal failure. One series reported 3 renal transplant patients who had hyperkalemia after labetolol infusion, but none of these patients developed any serious complication. We report a case of life-threatening hyperkalemia (serum [K+] 9.9 mEq/l) with ventricular tachycardia and hypotension in a patient on maintenance hemodialysis who received labetolol for a hypertensive emergency. Physicians should be aware of this potentially lethal complication, which is easily preventable.

Abstract
The Plasmodium falciparum population in Asar village, eastern Sudan, where malaria transmission is markedly seasonal, was monitored monthly over a period of 15 months. A cohort of infected patients was treated and then followed monthly throughout the dry season until the next transmission season. Parasitaemia detected by microscopy among the cohort reduced dramatically following treatment, but remained sporadic during the dry season, and reappeared following the onset of the next wet season. However between 40 and 50% of the cohort retained a persisting parasitaemia detectable by PCR throughout the dry season. These parasites were genetically complex, consisting of multiple clones with a large repertoire of alleles of the studied genes. While the number of clones per host dropped significantly following treatment of acute cases during the transmission season, drug treated people nevertheless maintained an average of one clone throughout the dry season. Allele frequencies of MSP-1, MSP-2 and GLURP showed slight, statistically insignificant, fluctuations between the dry and wet seasons. A higher frequency of inbreeding was estimated among the parasites that survived the dry season compared to the wet season.

Abstract
Vibrio cholerae causes epidemic diarrhea throughout the world. Fluid replacement is the primary therapy for cholera; however, high mortality rates often necessitate the use of antibiotics. V. cholerae, like most bacteria, has developed resistance to some antibiotics. In the early 1990s a new serotype strain, Bengal 0139, began a new wave of cholera epidemics. Bengal isolates showed unique trends in antimicrobial resistance. Many clinical laboratories use automated antibiotic susceptibility testing for V. cholerae. It is important to know if automated susceptibility test results for V. cholerae coincide with reported trends in antibiotic susceptibility. In the present study, we used the Vitek automated susceptibility system to determine the susceptibilities of 79 V. cholerae O1 isolates, 100 O139 isolates, and 112 non-O1 isolates. Vitek susceptibilities for V. cholerae showed a good correlation with preestablished epidemiological data. Although the new O139 serogroup showed a trend of increased resistance to trimethoprim-sulfamethoxazole and nitrofurantoin, it was more susceptible to ampicillin than previous serogroup O1 and non-O1 strains. Regardless of serogroup, > or = 98% of the V. cholerae isolates tested were susceptible to most antibiotics tested by us. It is important to continue susceptibility testing of all new isolates of V. cholerae because of emerging resistant strains. However, V. cholerae remains susceptible to most of the available antibiotics.
