ABSTRACT This study aimed to describe the perception about vaccines and the level of knowledge, attitudes and practices towards COVID-19 in older adults from a hospital in Lima, Peru. Descriptive and cross-sectional study carried out from March to November 2021. An instrument was adapted and validated to measure the level of knowledge, attitudes and practices; the perception about vaccines was evaluated with an exploratory questionnaire. Eighty-three older adults were surveyed, the mean age was 74.0 years and 62.7% were women. Most of the participants knew the cause and symptoms, and 50.6% believed that it could be transmitted by contaminated food. Additionally, 61.7% used traditional medicine to prevent it, and 65.4% considered that the level of social awareness was insufficient; 91.5% were vaccinated against COVID-19, and 65.4% considered these vaccines to be safe. In conclusion, most older adults showed a high level of knowledge, attitudes and practices and a positive perception about the vaccine against COVID-19.

Management and Outcome of a Neurologically Intact Infant with Pierre Robin Sequence and Dandy-Walker Variant Diagnosed with Large Hemispheric Brain Abscess ­ Case Report

Pierre Robin sequence (PRS) is a condition consisting of three essential components: micrognathia or retrognathia, cleft palate, and glossoptosis. It can be part of multiple congenital anomalies. We present the case and outcome of a 3-month-old clinically stable patient who has PRS with Dandy-Walker variant ­ which is a rare presentation in the literature ­ with a large right hemispheric brain abscess, treated with multiple minimally-invasive surgical drainage procedures with adjuvant antibiotics.

Buckling of the Ligamentum Flavum as a Rare Complication of Anterior Cervical Corpectomy and Fusion: A Case Report

Introduction and Importance Neurological deterioration due to buckling of the ligamentum flavum (LF) is an uncommon complication after anterior cervical corpectomy or discectomy with fusion. Case Presentation In this report, we present the case of a 66-year-old male who underwent anterior cervical partial corpectomy of C5 and discectomy of prolapsed C5- C6 with fusion. Postsurgery, the patient displayed signs of neurological deterioration. Upon immediate cervical magnetic resonance imaging (MRI), posterior canal stenosis and severe compression with cord signal due to LF buckling were detected. A posterior laminectomy procedure and canal decompression at the C5-C6 level with bone fusion were performed. Clinical Discussion Patient presented with walking difficulty, then walking disability, followed by bilateral upper and lower limb paresthesia with burning sensation. Examination showed ⅘ muscle strength in both handgrips. Further investigation showed brisk deep tendon reflexes, positive Hoffman sign unilaterally, equivocal Babinski sign, and progressive quadriparesis. Magnetic resonance imaging showed mild and diffuse building of some cervical discs, with spinal cord progression. We performed an anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF); a titanium mesh with plates and screws was used for fusion, with removal of a calcified and herniated subligamentous disc. Postoperatively, upper and lower limb strength deteriorated; immediate cervical and thoracic MRI showed LF buckling, which caused canal stenosis and severe compression. Urgent posterior laminectomy and canal decompression with bone fusion was scheduled on the same day. The patient underwent physiotherapy and regained upper and lower limb strength and his ability to walk. Conclusion This indicates the possibility of neurological deterioration as a result of LF buckling, whichmay be a result of LF thickening accompanied by hyperextension in the cervical region. In this regard, immediate imaging following signs of neurological complications after anterior cervical corpectomy or discectomy warrants early detection, which results in a better prognosis.

Potenciales efectos pro-arrítmicos de la farmacoterapia contra SARS-CoV-2 / Potential pro-arrhythmic effects of pharmacotherapy against SARS-CoV-2

Resumen La pandemia por el virus SARS-COV-2 causante de la enfermedad COVID-19 representa un reto mundial dada su alta tasa de transmisión y ausencia de una terapia efectiva o vacuna. Este escenario ha propiciado el uso de diversos fármacos que in vitro han demostrado un potencial efecto contra el virus. Sin embargo, el tiempo no ha sido suficiente para evaluar su efectividad clínica con el adecuado rigor científico que precede a la prescripción de medicamentos. El uso de cloroquina/hidroxicloroquina, azitromicina y esquemas antivirales ha sido propuesto por diversos grupos, apoyado por series de pacientes limitada en número. Si bien puede representar la única esperanza para muchos enfermos, es importante conocer los principales efectos adversos asociados al uso de estas drogas y seleccionar mejor a los pacientes que puedan beneficiarse de ellas. El riesgo de arritmias ventriculares incrementa tanto por el uso de fármacos como por la gravedad de la propia enfermedad viral.

Abstract The pandemic caused by the SARS-COV-2 or COVID-19 virus has been a global challenge given its high rate of transmission and lack of effective therapy or vaccine. This scenario has led to the use of various drugs that have demonstrated a potential effect against the virus in vitro. However, time has not been enough to properly evaluate their clinical effectiveness. The use of chloroquine/hydroxychloroquine, azithromycin and antiviral treatment and has been proposed by various groups, supported by in-vitro studies and limited patient series, without the adequate scientific rigor that precedes drug prescription. Although it may represent the only hope for many patients, it is important to know the main adverse effects associated with the use of these drugs and to better select patients who may benefit from them.

Survival of patients with non-small cell lung cancer in King Abdulaziz University Hospital, Jeddah, Saudi

Background: The improvement in the survival rate from cancer is increased due to advancement in the early detection, combined modality therapy and right therapeutic strategies. This study was aimed to assess the survival outcomes of patients diagnosed with non-small cell lung cancer (NSCLC) at King Abdulaziz University Hospital (KAUH).Methods: This retrospective cohort study included all patients aged 14 years and older with a diagnosis of NSCLC from 2007 to 2017 using electronic medical records at KAUH. Data analysis was performed by using Stata SE, version 15.0. Survival was defined as the time the patient lived in months from the date of pathological diagnosis to the date of last follow-up or death. All variables in a univariate and multivariate analysis were included.Results: Adenocarcinoma was the most common type of NSCLC observed in both genders, accounting for 43.70% of all cases. Of the patients diagnosed with NSCLC the overall median survival was 12.2 months (interval=16.9). And among all variables, surgical treatment was associated with a 71% relative reduction in risk of death (hazard ratio 0.29, p<0.014), and chemotherapy a 57% relative reduction in risk of death (hazard ratio 0.43, p<0.013).Conclusions: The median age of diagnosis of NSCLC in Kingdom of Saudi Arabia (KSA) was younger than United States of America, this could be due to many factors including smoking. The number of lung cancer cases among women was lower than men.

Efficacy of a public promotion program on children's oral health / Eficácia de um programa público de promoção de saúde bucal em crianças

Abstract Objective: To assess the efficacy of the Baby's Mouth early dental care prevention and promotion program in preventing oral diseases (caries, gingivitis, or malocclusions) in children attended since 2010. Methods: This was a cross-sectional and cohort study that assessed 252 children between 36 and 60 months of age in both sexes. The children were divided into three groups: G1: effective participants of the program from birth; G2: children who have stopped participating for more than 24 months, and G3: children who have never attended a prevention program. The evaluation was carried out in two stages: first, an interview with the mothers and, afterwards, a clinical children examination to assess the presence of caries, gingivitis, and malocclusion. The chi-squared test was used for statistical analysis between groups (p < 0.05). Results: The diseases assessed were: caries (G1: 5.9%, G2: 54.7%, G3: 70%), gingivitis (G1: 8.3%, G2: 17.9%, G3: 40.5%), and malocclusion (G1: 22.6%; G2: 28.6%; G3: 50%). For gingivitis, there was no significant difference when comparing G1 and G2 (p = 0.107), but it was significant between G1 and G3 (p < 0.001). Regarding malocclusion, a statistically significant relationship was observed (p = 0.004) among all groups. Conclusion: The prevention and promotion program in public oral health was effective in preventing caries disease, gingivitis, and malocclusion in children under 5 years of age.

Resumo Objetivo: Avaliar a eficácia do programa de prevenção e promoção de cuidados dentários precoce da boca do bebê, a fim de prevenir doenças bucais (cáries, gengivite ou má oclusões) em crianças atendidas desde 2010. Métodos: Estudo transversal e de coorte com avaliação de 252 crianças entre 36 e 60 meses de idade de ambos os sexos. As crianças foram divididas em dois grupos: G1: participantes efetivos do programa a partir do nascimento; G2: crianças que pararam de participar por mais de 24 meses do programa; e G3: crianças que nunca participaram de um programa de prevenção. A avaliação foi feita em dois estágios: entrevista com as mães e, depois, um exame clínico nas crianças para analisar cáries, gengivite e oclusão. Foi utilizado o teste qui-quadrado para análise estatística entre os grupos (p < 0,05). Resultados: As doenças analisadas foram: cáries (G1: 5,9%, G2: 54,7%, G3: 70%), gengivite (G1: 8,3%, G2: 17,9%, G3: 40,5%) e má oclusão (G1: 22,6%; G2: 28,6%; G3: 50%). Para gengivite, não houve diferença significativa ao comparar G1 e G2 (p = 0,107), porém a diferença foi extremamente significativa entre G1 e G3 (p < 0,001). Nas oclusões, houve uma relação estatisticamente significativa (p = 0,004) entre todos os grupos. Conclusão: O programa de prevenção e promoção de saúde bucal pública foi efetivo na prevenção de cáries, gengivite e má oclusão em crianças com menos de cinco anos de idade.

The Relationship between Saccades and Locomotion

Human locomotion involves a complex interplay among multiple brain regions and depends on constant feedback from the visual system. We summarize here the current understanding of the relationship among fixations, saccades, and gait as observed in studies sampling eye movements during locomotion, through a review of the literature and a synthesis of the relevant knowledge on the topic. A significant overlap in locomotor and saccadic neural circuitry exists that may support this relationship. Several animal studies have identified potential integration nodes between these overlapping circuitries. Behavioral studies that explored the relationship of saccadic and gait-related impairments in normal conditions and in various disease states are also discussed. Eye movements and locomotion share many underlying neural circuits, and further studies can leverage this interplay for diagnostic and therapeutic purposes.

Screening of the Anti-hyperglycemic activity of some medicinal plants of Jordan

Diabetes represents a group of common diseases that are characterized by dysregulation of blood glucose levels. Plants are traditionally used for management of diseases including diabetes. In this study, we screened the antidiabetic effect of extracts of 21 plants grown in Jordan. Extracts of plants were screened for their antihyperglycemic activity. Diabetes was induced in Sprague Dawley rats using Alloxan. Plant extracts were dosed at 1gm/kg. Blood glucose was measured at baseline and at every hour for 3 hours. Results showed that five plants out of the 21 screened showed antihyperglycemic activity. These plants are Phoenix dactylifera L., Tecoma stans [L.] Kunth, Cichorium pumilum Jacq., Phaseolus vulgaris L., and Teucrium polium L. On the other hand, Sarcopoterium spinosum [L.] Spach. and Brassica oleracea L. var. capitata significantly increased blood glucose levels in diabetic rats. The following plant extracts showed neutral effect on blood glucose levels: Plantago major L., Taraxacum cyprium H. Lindb, Artemisia inculta Delile, Marrubium vulgare L., Inula viscosa [L.] Ai, Rubus sanguineus Friv, Coriandrum sativum L., Cucurbita pepo var ovefera, Cucumis sativus L., Hordeum vulgare L., Apium graveolens L., Avena sativa L., Helianthus annus L., and Anethum graveolens L. In conclusion, Jordanian medicinal plants might be useful for managements of blood glucose levels in patients with diabetes

Tumours of the Chest in Children: A Review

Tumours of the chest in children constitute an array of pathology and clinical symptomatology. These tumours can be benign or malignant; cystic or solid; primary or as a result of secondary metastases. Collectively; tumours of the chest in children are very rare; the exact incidence of which is largely unknown globally. Non neoplastic lesions of the lung including bronchogenic cysts; sequestrations; congenital pulmonary airway malformations as well as infective and inflammatory disorders are 60 times more common than neoplastic causes.1 A tumour of the chest is considerably difficult to diagnose since patients can be asymptomatic for many years before symptoms evolve. Even more so; the symptoms are non-specific and can suggest more common and less sinister pathology. Clinically patients present with a variety of symptoms that depend largely on the location of the tumour.Airway tumours can be symptomatic or can present with chronic cough; wheeze; haemoptysis; atelectasis or persistent pneumonia. Secondary malignant parenchymal tumours are likely to be symptomatic from the primary lesion. Anterior mediastinal tumours can cause compression of the large airways or superior vena caval structures.It stands to reason that the physician needs to have a very high index of suspicion when dealing with these non-specific signs and symptoms. This article provides an approach to tumours of chest and reviews the common aetiology in the different compartments of the chest. The article will focus on common tumours of the airway; lung parenchyma; mediastinum; cardiac and chest wall pathology

Association of Polymorphisms in DAZL Gene with Male Infertility.

Objectives: To investigate the association between A260G (Thr12Ala) and A386G (Thr54Ala) single nucleotide polymorphisms (SNPs) in deleted in azoospermia-like gene (DAZL) and infertility in Jordanian males. Methods: Infertile 170 patients with azoospermia or oligozoospermia and 176 fertile subjects were recruited in the study. DAZL SNPs were genotyped using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP). Results: The data showed that the A260G SNP is common in the Jordanian population with frequency of 10.3% for 260G mutant allele. However, the A386G SNP is absent in the studied population. No significant association was found between the examined SNPs in DAZL gene and men infertility. Conclusion: The A260G and A386G polymorphisms of DAZL seem to play no role in men infertility in Jordanian population.

values of CA-125, progesterone, beta-HCG and estradiol in the early prediction of ectopic pregnancy

To explore the diagnostic value and measurement of serum CA-125, the single measurement of progesterone [P], beta-HCG, and estradiol [E2] in the early diagnosis of ectopic pregnancy. Serum levels of CA-125, progesterone, beta-HCG and estradiol were measured by Enzyme Linked Immuno Sorbent Assay [ELISA] techniques in 40 symptomatic women with ectopic pregnancy and 24 women with normal intrauterine pregnancy during gestational age of 4-10 weeks at Al-Kadhmiya Teaching Hospital, Baghdad, Iraq, between November 2010 and June 2011. The mean +/- SEM serum levels of CA-125, progesterone, beta-HCG, and estradiol in patients with ectopic pregnancies [16.51 +/- 2.39U/ml; 2.54 +/- 0.47ng/ml; 72.75 +/- 12.27mIU/ml; 13.4 +/- 2.14pg/ml; respectively] were significantly lower than the levels in normal intrauterine pregnancies [74.25 +/- 18.5U/ ml; 28.36 +/- 3.7ng/ml; 249.54 +/- 18.0mIU/ml; 112.7 +/- 23.6pg/ml; respectively]. When using a CA-125 concentration of 20.5 U/ml as a cut-off value for the diagnosis of ectopic pregnancy, sensitivity was 75.7%, specificity 100%, the positive predictive value was 100% and the negative predictive value 71.4%. The measurement of CA-125 and progesterone levels is useful in discriminating ectopic from normal gestations

Comparison between frequencies of several STRs loci in Jordan with neighboring countries

To investigate the frequencies of 9 autosomal Short Tandem Repeats [STR] loci in the Jordanian population and compare them with the frequencies in neighboring countries. DNA was extracted from the blood of 270 unrelated Jordanian individuals. CSFIPO, TPOX, THO1, F13AO1, FESFPS, vWA, D16S539, D7S820, DI3S317 Markers were detected by amplifying the extracted genomic DNA using GenePrint[TM] STR Multiplex system. For each Marker, 6-9 alleles were observed. Markers D7S820 and D13S317 had the highest Power of Discrimination [PD] values while TPOX was the least informative marker. Marker D16S539 is significantly different in Jordanian population compared to all other neighboring populations. Marker D16S539 is very powerful for discriminating between Jordanian and other populations from neighboring countries. The combination between these 9 SRS loci seems to be a powerful tool for individual identification in the region
